I made a Python program to repeat the number of internships that I applied for, BUT I need it to store the amount I add so that I can ask it later how many I applied for, rather than me having to enter a number every time. Also, I want it to be able to update if the number of internships I applied for changes, I will input the new number of internships manually. How can I change my program to do that? Please take a look thanks
print("Welcome back, Ryan")
internships = {}
asking_ryan = True
amount = input("Enter how many internships you have applied for: ")
amount = int(amount)
if amount > 1:
print("You have applied for: " + str(amount) + " internship(s)")
str(amount)
if amount < 1:
print("Error! you cannot apply for 0 internships!")
if amount == 1:
print("You have applied for: " + str(amount) + " internship")
Program output:
Welcome back, Ryan.
Enter how many internships you have applied for: 2
You have applied for: 2 internship(s)
I saw your question. I kind of understand it.
You want to be able to update the internships you have done so you don't have to always rerun the program so it counts your internship?
You might have to use some files for that, should be simple!
First, you can make a file called opens.txt and add a 0 to the file that tracks how many times you opened that program. When you run the program do this:
opens = open("opens.txt", w+)
open_count = int(opens.read())
opens.write(open_count + 1)
if open_count == 1:
amount = input("Enter how many internships you have applied for: ")
... # Other Code
Then make a file called something like internships.txt where it will store how many internships you currently have, default it to 0.
internships = open("internships.txt", w+)
internship_count = int(internships.read())
print("You currently have applied to {} internships since last time...".format(internship_count)
new_internships = input("How many new internships have you applied for? ")
internships.write(internship_count + new_internships)
I think this should help? Haven't used files in a long time. Next time please phrase your question a bit better.

I'm new to python and there's a video on Youtube that I watched. I do the exact same code as he but mine doesn't work and I don' understand why.
Here's the code:
MAX_LINES = 3
def deposit():
while True:
amount = input("What would you like to deposit? $")
if amount.isdigit():
amount = int(amount)
if amount > 0:
break
else:
print("Amount must be greater than 0. ")
else:
print("Please enter a number. ")
return amount
def get_number_of_lines():
while True:
lines = input("Enter the number of lines to bet on (1-" + str(MAX_LINES) + ")? ")
if lines.isdigit():
lines = int(lines)
if 1 <= lines <= MAX_LINES:
break
else:
print("Please enter a valid number of lines. ")
else:
print("Please enter a number. ")
return lines
There are 3 problems.
Unindent amount does not match previous indent. I have no idea what does that mean
"return" can be used only within a function. As far as I'm concerned I'm using it in the function, copied the first function then pasted it into the second function and somehow it doesn't work
"lines" is not defined. What dou you mean it's not defined, I define it in the first line of the function
https://www.youtube.com/watch?v=th4OBktqK1I
This video's code what I'm trying to do
I appreciate any help!
I just simply don't understand why it works in one and not the other
You have one space too much in front of while True in function get_number_of_lines().
Yes used in functions to return value
Because function don't get inside while loop (because of indent problem), lines is never defined, probably this was the problem.
So try fix indent and run again
So basically I have this number guessing game for my school project-
import random
import math
lower = int(input("Enter Lower bound:- "))
upper = int(input("Enter Upper bound:- "))
x = random.randint(lower, upper)
def num_of_chances(U,L):
return round(math.log(U - L + 1, 2))
print("You've only ",num_of_chances(upper,lower)," chances to guess the integer!")
count = 0
while count < num_of_chances(upper,lower):
count += 1
guess = int(input("\nGuess a number:- "))
if x == guess:
print("\nCongratulations you did it in ",count, " try")
break
elif x > guess:
print("You guessed too small!")
elif x < guess:
print("You Guessed too high!")
if count >= math.log(upper - lower + 1, 2):
print("\nThe number is %d"% x)
print("\tBetter Luck Next time!")
I had to somehow implement file handling into this code, so I though about doing something which allows the user to play multiple times and keep track of their wins/ losses and to save the username (which will have to ask for) and the wins/ losses in a file and allow the user to view the leaderboard pulled from that file.
Thing is the codes based on file handling which I have practiced were way simpler than this, and I do not really understand how do I go about to approach this. I have the deadline in 2 hours, and I have absolutely no idea what to do right now(I wasn't slacking off before this, I actually was studying the entire time for an extremely competitive entrance exam).
Please suggest me the approach that I should go about to code this, keeping it as simple as possible, and also if possible write the code, I'll be more than grateful !
It depends on how you want to do the filehandling; do you want to have it in a .txt file for each user, do you want a .csv file, are you allowed to use other libraries for the file-handling (e.g pandas). You write ".txt" file in the title, but do not mention if it has to be a .txt file in the question.
You can create a simple .csv file with the structure
#user_stats.csv
username,wins,loss
eg.
#user_stats.csv
user,wins,loss
user1,5,10
user2,3,100
user3,0,1
which you read/write using pandas.read_csv (docs) or df.to_csv("user_stats.csv",index=False") (docs).
Then you just load that in the beginning:
username = input("Enter username:")
df_stats = pd.read_csv("user_stats.csv") #load stats
df_stats = df_stats.loc[df_stats["user"]==username] #Get user with the provided username (if exists)
.
.
.
Then you can just increment df_stats["wins"] by 1 if they win or the loss by 1 if they loose.
Make sure to handle the difference between a new user and when the username is incorrect when you load the user_stats at the beginning (if you want to)
So I am a total beginner yet this is 100% my code and I am proud of it. Now mind you I need a little cleaning up, however it does what I want it too. My issue is this: In order to turn this in for credit, one of the things is that procedures(functions) should not contain more than 18 lines. My function gameCont() has many more. Would anyone have suggestions on how I could shorten it up? Additionally I am obviously challenged when it comes to function parameters so any help is appreciated. Please be gentle as I am BRAND NEW! :)

Two suggestions:
Delegate tasks that are accomplished by your function to smaller functions. So, for example, if you had a function that needed perform task A and performing that task could be divided into tasks B, C, and D, then create helper functions and call them inside of the function that does task A.
You have long strings, maybe store them somewhere else? Create a class just for constant strings of related functions and access that when you need a particular string. It'll make it less likely that you'll make a mistake when you need to use that string in multiple locations.
class Constants:
str1 = "..."
str2 = "..."
print(Constants.str1)
you can call a function from inside another function. inside an if statement you could call a small new function that just prints some stuff. this should make it easy to get the function size down.
something like this should work:
def correct(quiz, blanks):
print "As you can see your correct choice has replaced the variable, great job!!"
quiz = quiz.replace("_" + str(blanks) +"_", answers[blanks - 1]) # here is the line of code that replaces the blank with the correct guess
blanks += 1 # this adds 1 to the blank which will prompt the user to move to the NEXT blank when loop begins again
if blanks > len(answers):
print ("\n" * 10)
print "YOU DID IT!! Here is the final paragraph with all the correct answers"
print ("\n" * 2)
print quiz`
remember that you still want to break after calling that function in order to exit your loop.
I'm very new to Python and programming in general, so excuse me if the code is terrible and the problem rather easy to solve.
I have written code to allow a user to have employee data printed based on 3 different inputs, which they are allowed to choose from.
The options the user has available to them are to pick employees based on their payroll number; a minimum and maximum salary range; their job title.
I made two functions for the formatting. The first one turns the lines of the text file into lists, then the second function grabs those individual lists and formats them.
Then the code requests the user to input the file name. If the file cannot be found, they get to try again. If it is correct, the file is loaded and then runs through the functions to print out a neat table.
Then the user is asked what method they want to choose from to select specific employees. They are given 4 options, 3 are mentioned at the start and the fourth is to just end the program.
I managed to successfully get the first option to print out the employees without hassle, as is the same for the fourth option to end the program. I almost have the third one completed, I just need to find a way to print the name without a comma. My problem resides within the second option: how do I print the employees and their details if they fall between the minimum and maximum salary ranges entered by the user if the range isn't an integer since it has to include a '£' sign?
Here's the code. It's the biggest chunk in the program because I just have no clue how to make it work properly -
def detailsPrint(field) : #takes tuple and prints
print("{:30}" "{:6}" "{:15}" "{:7}".format(field[3] + ", " + field[4], field[0], field[2], "£" + field[1]))
if display == 2 :
maxSalary = "£1000000"
minpay = input("Enter the minimum pay : ")
maxpay = input("Enter the maximum pay : ")
if len(minpay) and len(maxpay) < maxSalary :
for s in employeeList :
if s[1] >= minpay :
detailsPrint(s)
The outcome should be something like (example) Simpson, Bart 12345 Consultant £55000 if the minpay were to be £50000 and maxpay £60000
edit: Managed to get it working. Here's the code
if display == 2 :
x = False
maxSalary = 1000000
minpay = int(input("Enter the minimum pay: "))
maxpay = int(input("Enter the maximum pay: "))
if int(minpay) > int(maxSalary) or int(maxpay) > int(maxSalary) :
x = False
print("No employees earn over £1000000. Try again.")
if int(minpay) or int(maxpay) < int(maxSalary) :
for s in employeeList :
if int(s[1]) >= minpay and int(s[1]) <= maxpay :
detailsPrint(s)
x = True
if x == False :
print("No employees could be found within that range. Try again")
print("\n")
Simplest solution: don't ask for the £ char ;-)
A solution that work with your requirement is to change the line
if len(minpay) or len(maxpay) > maxSalary :
with something like
if int(minpay[1:]) > int(maxSalary[1:]) or int(maxpay[1:]) > int(maxSalary[1:]) :
which check the numeric value of the strings (your condition seems wrong anyway to me)
You could replace all "£" signs to "" in a string.
YourString.replace("£", "")

This is my first post here and I am quite unsure on how to implement a vital piece of code in my coursework. I have created a very crude and basic recipe program on Python 3.4. Below is the piece I am missing.
• The program should ask the user to input the number of people.
• The program should output:
• the recipe name
• the new number of people
• the revised quantities with units for this number of people.
I am a complete beginner to programming and our teacher hasn't been very helpful and only explained the basics of file handling which I have attempted to implement into this program.
I will attach the code I have so far, but I would really appreciate some tips or an explanation on how I could implement this into my code and finally finish this task off as it is becoming very irksome.
Thank you!

I apologise if the code is cluttered or doesn't make sense. I am a complete novice.

EDIT: This is the new code, however I can still not figure out how to allow a user to multiply the original servings by entering how many servings are required, as the default servings are in a text file. Does anyone know how this can be done? I am new to file-handling and have been researching constantly but to no avail.
For the number of people, you can get that from user input similar to how you got any other input in your code, with num_people = input("How many people?").
Something a little more concerning you should look at. Your start() function calls its self. Unless you are using recursion, functions should not call themselves, it will build up on the stack. Use a while loop with something like
while ( 1 ):
userinput = input("what would you like to do?")
if( userinput == "n"):
#new recipe
....
if (user input == "quit"):
sys.exit(1) #this will halt the program
else:
print "not valid input"
You stored the whole data in a text file. This makes storage and retrieval easy, but makes changing values real hard. In these cases, you usually use ... well nevermind: you asked the same question again and got a useful answer.
