So basically, i needed to write a program that takes the time of how fast you run a kilometer, and turn it into how long it takes to run a marathon. I got that done, but the problem is that it is supposed to handle if someone inputs the time incorrectly (ex 888 or 5:2555 instead of 8:30)
print "Marathon Time Calculator"
str_pace = raw_input("At what pace do you run a km? (e.g. 5:30): ")
if str_pace.isalpha():
print 'invalid time'
split_pace = str_pace.split(":")
minutes = int(split_pace[0])
seconds = int(split_pace[1])
str_pace = minutes * 60 + seconds
totalTime = str_pace * 42
hours = totalTime // 3600
timeLeft = totalTime % 3600
minutes = timeLeft // 60
seconds = timeLeft % 60
if len(split_pace[1]) >= 3:
print "Too many digits"
else:
print "You should complete a marathon in " + str(hours) + ":" + str(minutes) + ":" + str(seconds)
I have done this in python3
import re
import sys
print("Marathon Time Calculator")
str_pace = input("At what pace do you run a km? (e.g. 5:30): ")
# this is looking for a decimal value of 1 number, then a colon then another decimal value of 1 - 2 numbers
pattern = '\d{1}\:\d{1,2}'
# this is doing the actual check against the pattern for us
match = re.match(pattern, str_pace)
# we now check if there is a match to our pattern
if not match:
print('Invalid Time Input Try Again')
sys.exit
else:
# yes we are entering the value correctly continue the code
split_pace = str_pace.split(":")
minutes = int(split_pace[0])
seconds = int(split_pace[1])
str_pace = minutes * 60 + seconds
totalTime = str_pace * 42
hours = totalTime // 3600
timeLeft = totalTime % 3600
minutes = timeLeft // 60
seconds = timeLeft % 60
print("You should complete a marathon in {}:{}:{}".format(hours, minutes, seconds))

I'm looking for a cooldown timer for python, basically just to print days,hours,minutes,seconds left from a certain date.
Thanks very much!
You can get the counter with the help of time delta function.
import datetime
import time
future_date = datetime.datetime.now()+ datetime.timedelta(seconds=3)
while True:
curr_date = datetime.datetime.now()
rem_time = future_date - curr_date
total_seconds = int(rem_time.total_seconds())
if total_seconds > 0:
days, h_remainder = divmod(total_seconds, 86400)
hours, remainder = divmod(h_remainder, 3600)
minutes, seconds = divmod(remainder, 60)
print("Time Left: {} days, {} hours, {} minutes, {} seconds".format(days, hours, minutes, seconds))
time.sleep(1)
else:
break
sample output will be:
Time Left: 0 days, 0 hours, 0 minutes, 2 seconds
Time Left: 0 days, 0 hours, 0 minutes, 1 seconds
Try this. The module datetime is preinstalled on Python, I believe.
import datetime
while True:
print("\033[H\033[J")
present = datetime.datetime.now()
future = datetime.datetime(2022, 3, 31, 8, 0, 0)
difference = future - present
print(difference)
The format for datetime's future is: year, month, day, hour, minute, second.
Or, if you'd like to have user input:
import datetime
year = int(input('Enter the year of the end date: '))
month = int(input('Enter the month of the end date: '))
day = int(input('Enter the day of the end date: '))
hour = int(input('Enter the hour of the end date: '))
minute = int(input('Enter the minute of the end date: '))
second = int(input('Enter the second of the end date (a little tricky): '))
future = datetime.datetime(year, month, day, hour, minute, second)
while True:
print("\033[H\033[J")
present = datetime.datetime.now()
difference = future - present
if present >= future:
break
print(difference)
print('Time reached!')
You can use the seconds from a timedelta from subtracting two dates to calculate the days, hours, minutes and seconds like this:
from datetime import datetime
import time
totalSecs = 1 #So the while loop doesn't stop immidiately
while totalSecs > 0:
startDate = datetime.now() #Can be any date
endDate = datetime(2021, 12, 25)
delta = endDate - startDate
totalSecs = delta.total_seconds()
days = divmod(totalSecs, 86400)
hrs = divmod(days[1], 3600)
mins = divmod(hrs[1], 60)
seconds = divmod(mins[1], 1)
print("{:02d}:{:02d}:{:02d}:{:02d}".format(int(days[0]), int(hrs[0]), int(mins[0]), int(seconds[0]))) #Zero pad all the numbers
time.sleep(1) #Print every second.
Thank you all for your replies, i've done a mistake when i made the post. Is not from a date. Is a countdown in day,hours,minutes,seconds from a certain amount of seconds. Let's say i've got 31104000 seconds and i want to print how many days,hours,minutes,seconds left from that amount of seconds.
The code i've got now is a bit trivial and i can't print seconds in realtime.
def SecondToDHM(time):
if time < 60:
return "%.2f %s" % (time, SECOND)
second = int(time % 60)
minute = int((time / 60) % 60)
hour = int((time / 60) / 60) % 24
day = int(int((time / 60) / 60) / 24)
text = ""
if day > 0:
text += str(day) + DAY
text += " "
if hour > 0:
text += str(hour) + HOUR
text += " "
if minute > 0:
text += str(minute) + MINUTE
text += " "
if second > 0:
text += str(second) + SECOND
return text
import datetime
a = datetime.datetime.now()
"%s:%s.%s" % (a.minute, a.second, str(a.microsecond))
I am trying to get the Seconds since midnight: 86339
I tried writing a program and i get the results
Enter hour:11
Enter minute:58
Enter second:59
Enter frame:PM
Seconds since midnight: 43139
hour = input("Enter hour:")
minute = input("Enter minute:")
second = input("Enter second:")
frame = raw_input("Enter frame:")
time = ( 3600 * hour + minute * 60 + second )
print "Seconds since midnight:",time
This is the actual results i want to produce
Enter hour: 11
Enter minute: 58
Enter second: 59
Enter AM or PM: PM
Seconds since midnight: 86339
Enter hour: 12
Enter minute: 7
Enter second: 20
Enter AM or PM: AM
Seconds since midnight: 440
Enter hour: 12
Enter minute: 14
Enter second: 57
Enter AM or PM: PM
Seconds since midnight: 44097
PM needs to add 12 hours
Python 2.X :
hour = input("Enter hour:")
minute = input("Enter minute:")
second = input("Enter second:")
frame = input("Enter frame:")
time = ( 3600 * hour + minute* 60 + second )
if frame == "PM":
time += 12 * 60 * 60
print "Seconds since midnight:",time
Python 3.x:
hour = input("Enter hour:")
minute = input("Enter minute:")
second = input("Enter second:")
frame = input("Enter frame:")
time = ( 3600 *int( hour) + int( minute)* 60 + int( second ))
if frame == "PM":
time += 12 * 60 * 60
print("Seconds since midnight:",time)
Change your time calculation to something like this:
time = ( 3600 * hour + minute * 60 + second )
if "PM" == frame:
time += 12 * 60 * 60
I am wondering how to calculate the amount of time it would take to example:
Complete a brute force word list.
I know how to use the time function and measure in time,
but the problem is i need to find out how long it would take in the program itself...
Here is the code i made this yesterday
import itertools, math
import os
Alphabet = ("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890") # Add or remove whatevs you think will be in the password you're cracking (example, [symbols])
counter = 1
CharLength = 1
range_num = int(raw_input("Enter range: "))
stopper = range_num + 1
filename = "bruteforce_%r.txt" % (range_num)
f = open(filename, 'a')
#n_1 = len(Alphabet)
#n_2 = n_1 - 1 # <-- total useless peice of garbage that could of been great in vurtual life
#n_3 = '0' * n_2
#n = '1' + n_3
x = range_num
y = len(Alphabet)
amount = math.pow(y, x)
total_items = math.pow(y, x)
for CharLength in range(range_num, stopper):
passwords = (itertools.product(Alphabet, repeat = CharLength))
for i in passwords:
counter += 1
percentage = (counter / total_items) * 100
amount -= 1
i = str(i)
i = i.replace("[", "")
i = i.replace("]", "")
i = i.replace("'", "")
i = i.replace(" ", "")
i = i.replace(",", "")
i = i.replace("(", "")
i = i.replace(")", "")
f.write(i)
f.write('\n')
print "Password: %r\tPercentage: %r/100\tAmount left: %r" % (i, int(percentage), amount)
if i == '0'* range_num:
print "*Done"
f.close()
exit(0)
else:
pass
This is my timer function i managed to make

#os.system('cls') # Windows
minutes = int(raw_input('Enter the minutes.\n>>> '))
os.system('clear') # linux
#os.system('cls') # Windows
seconds = int(raw_input('Enter the seconds.\n>>> '))
os.system('clear') # Linux
#os.system('cls') # Windows
stop_time = '%r:%r:%r' % (hours, minutes, seconds)
t_hours = 00
t_minutes = 00

break
elif t_seconds == 60:
t_minutes+=1
t_seconds=0

exit(0)
Now i just cant figure out how to make this again but to calculate how long it will take rather than how long it is taking...
You cannot predict the time a script is going to take.
Firstly because two machines wouldn't run the script in the same time, and secondly, because the execution time on one machine can vary from on take to another.
What you can do, however, is compute the percentage of execution.
You need to figure out, for example, how many iterations your main loop will do, and calculate at each iteration the ratio current iteration count / total number of iterations.
Here is a minimalist example of what you can do:
n = 10000
for i in range(n):
print("Processing file {} ({}%)".format(i, 100*i//n))
process_file(i)
You can take it further and add the time as an additional info:
n = 10000
t0 = time.time()
for i in range(n):
t1 = time.time()
print("Processing file {} ({}%)".format(i, 100*i//n), end="")
process_file(i)
t2 = time.time()
print(" {}s (total: {}s)".format(t2-t1, t2-t0))
The output will look like this:
...
Processing file 2597 (25%) 0.2s (total: 519.4s)
Processing file 2598 (25%) 0.3s (total: 519.7s)
Processing file 2599 (25%) 0.1s (total: 519.8s)
Processing file 2600 (25%)
This is my implementation, which returns time elapsed, time left, and finish time in H:M:S format.
def calcProcessTime(starttime, cur_iter, max_iter):
telapsed = time.time() - starttime
testimated = (telapsed/cur_iter)*(max_iter)
finishtime = starttime + testimated
finishtime = dt.datetime.fromtimestamp(finishtime).strftime("%H:%M:%S") # in time
lefttime = testimated-telapsed # in seconds
return (int(telapsed), int(lefttime), finishtime)
Example:
import time
import datetime as dt
start = time.time()
cur_iter = 0
max_iter = 10
for i in range(max_iter):
time.sleep(5)
cur_iter += 1
prstime = calcProcessTime(start,cur_iter ,max_iter)
print("time elapsed: %s(s), time left: %s(s), estimated finish time: %s"%prstime)
Output:
time elapsed: 5(s), time left: 45(s), estimated finish time: 14:28:18
time elapsed: 10(s), time left: 40(s), estimated finish time: 14:28:18
time elapsed: 15(s), time left: 35(s), estimated finish time: 14:28:18
....
You will never ever be able to know exactly how long it is going to take to finish. The best you can do is calculate was percentage of the work you have finished and how long that has taken you and then project that out.
For example if you are doing some work on the range of numbers from 1 to 100 you could do something such as
start_time = get the current time
for i in range(1, 101):
# Do some work
current_time = get the current time
elapsed_time = current_time - start_time
time_left = 100 * elapsed_time / i - elapsed_time
print(time_left)
Please understand that the above is largely pseudo-code
The following function will calculate the remaining time:
last_times = []
def get_remaining_time(i, total, time):
last_times.append(time)
len_last_t = len(last_times)
if len_last_t > 5:
last_times.pop(0)
mean_t = sum(last_times) // len_last_t
remain_s_tot = mean_t * (total - i + 1)
remain_m = remain_s_tot // 60
remain_s = remain_s_tot % 60
return f"{remain_m}m{remain_s}s"
The parameters are:
i : The current iteration
total : the total number of iterations
time : the duration of the last iteration
It uses the average time taken by the last 5 iterations to calculate the remaining time. You can the use it in your code as follows:
last_t = 0
iterations = range(1,1000)
for i in iterations:
t = time.time()
# Do your task here
last_t = time.time() - t
get_remaining_time(i, len(iterations), last_t)
I have a database column the holds timestamps in UNIX format, I am looking for a way to compare those timestamps to a timestamp from the time right now and print how many seconds/hours/days since the original timestamp.
Just to confirm I am NOT looking for a conversion from 1489757456 to 03/17/2017 # 1:30pm. I AM looking for a conversion from 1489757456 to 1m ago/2hr ago/3d ago ect.
datetime.datetime.fromtimestamp()
to convert your unix timestamp to a datetitme
datetime.datetime.now()
to get the current datetime
dateutil.relativedelta.relativedelta(dt1, dt2, ...)
to get the difference with respect to leap years.

Function, like this will generate output for hours, mins and seconds from seconds number.
def secondsToHms(d):
d = int(d);
h = math.floor(d / 3600)
m = math.floor(d % 3600 / 60)
s = math.floor(d % 3600 % 60)
htext = " hour, " if h == 1 else " hours, "
hDisplay = str(h) + htext if h > 0 else ""
mtext = " minute, " if m == 1 else " minutes, "
mDisplay = str(m) + mtext if m > 0 else ""
stext = " second" if s == 1 else " seconds"
sDisplay = str(s) + stext if s > 0 else ""
return hDisplay + mDisplay + sDisplay;
For example:
secondsToHms(344334)
>> 95.0 hours, 38.0 minutes, 54.0 seconds
So you can add your preferred formatting and also add days/months if needed in similar fashion.
I want to write a program that allows the user to enter in a start time hour, end time hour, and number of divisions.
So they might enter 9, 10, and 4 which should mean a start time of 9:00AM, end of 10:00AM and to split the range 4 times, resulting in an output of 9:00, 9:15, 9:30, 9:45.
I've tried using the time module and datetime, but cannot get the addition of time to work. I do not care about date.
I can calculate the time split, but the actual addition to the start time is evading me.
I have a hodge-podge of code, and the following is mostly me experimenting trying to figure out how to make this work. I've tried adding the minutes, tried converting to seconds, delved into datetime, tried the time module, but can't seem to get it to work. There are plenty of examples of how to "add 15 minutes to now" but the issue is I don't want to start at the "now", but rather let the user decide start time.
Thank you.
time_start = "9"
time_end = "10"
time_split = "4"
if len(time_start) == 1:
time_start = "0" + str(time_start) + ":00"
else:
time_start = str(time_start) + ":00"
if len(time_end) == 1:
time_end = "0" + str(time_end) + ":00"
else:
time_end = str(time_end) + ":00"
print time_start
print time_end
s1 = time_start + ':00'
s2 = time_end + ':00'
FMT = '%H:%M:%S'
tdelta = datetime.strptime(s2, FMT) - datetime.strptime(s1, FMT)
divided = tdelta / int(time_split)
print tdelta
print divided
s3 = str(divided)

print "s2 time end: " + str(s2)
print "s3 time divided: " + str(s3)
ftr = [3600,60,1]
add_seconds = sum([a*b for a,b in zip(ftr, map(int,s3.split(':')))])
print "s3 time divided seconds: " + str(add_seconds)
print "time delta: " + str(tdelta)
EDIT: I did a small bit of research and found a much better solution that elegantly handles resolution to the millisecond. Please implement this code instead (though I will save the old code for posterity)
import datetime
start_time = 9 # per user input
end_time = 10 # per user input
divisions = 7 # per user input
total_time = end_time - start_time
start_time = datetime.datetime.combine(datetime.date.today(),datetime.time(start_time))
end_time = start_time + datetime.timedelta(hours=total_time)
increment = total_time*3600000//divisions # resolution in ms
times = [(start_time+datetime.timedelta(milliseconds=increment*i)).time()
for i in range(divisions)]
from pprint import pprint
pprint(list(map(str,times)))
# ['09:00:00',
# '09:08:34.285000',
# '09:17:08.570000',
# '09:25:42.855000',
# '09:34:17.140000',
# '09:42:51.425000',
# '09:51:25.710000']
If I were you, I'd do my math as raw minutes and use datetime.time only to save the results as something more portable.
Try this:
import datetime
start_time = 9 # per user input
end_time = 10 # per user input
divisions = 4 # per user input
total_minutes = (end_time-start_time)*60
increment = total_minutes // divisions
minutes = [start_time*60]
while minutes[-1] < end_time*60:
# < end_time*60 - increment to exclude end_time from result
minutes.append(minutes[-1] + increment)
times = [datetime.time(c//60,c%60) for c in minutes]
# [09:00:00,
# 09:15:00,
# 09:30:00,
# 09:45:00,
# 10:00:00]
