Print to the same line and not a new line? [duplicate]
(19 answers)
Closed 3 years ago.
I am using an API where I can fetch data with. From the data output I am trying to get specific portions so I can place it nicely in a formatted text.
I want to fetch the data every 5 seconds, so I get fresh info. I do not want that the data is prompted below the output from the first run, but rather replace the current value(s) for the updated value(s).
As I'm pretty bad with python, I hope someone can give me some advice.
import requests
import threading
def dostuff()
threading.Timer(5.0, dostuff).start()
r = requests.get('https://api')
data = r.json()
print("Amount:", data['amount'])
print("Games played:", data['matches'])
dostuff()
This works fine. It just keeps posting the output under each other.
I wish to have everything static, except the data['amount'], and data['matches'], which should keep updating without actually posting it on newlines. I have tried resolving this by clearning the screen, but that is not the desired solution.
Just add end='\r' to your print statement:
import requests
import threading
import random
def dostuff():
threading.Timer(1.0, dostuff).start()
# replaced as actual api not posted
data = {
'amount': round(random.random(), 2),
"matches": round(random.random(), 2)
}
print("Amount: {} Games played: {}".format(
data['amount'],
data['matches']
), end='\r')
dostuff()

How to concatenate (join) items in a list to a single string
(11 answers)
Closed 2 years ago.
I'm relatively new to python,
I built a webscraper that gets the top posts of a website and stores them in a list in python like this:
T = ["post1","post2","post3,"post4"]
To send the push notification with pushover I installed the pushover module that works like this:
from pushover import Pushover
po = Pushover("My App Token")
po.user("My User Token")
msg = po.msg("Hello, World!")
po.send(msg)
I want to send the list as a message with format, like this:
Top Posts:
1. post 1
2. post 2
3. post 3
4. post 4
I tried this:
msg = po.msg("<b>Top Posts:</b>\n\n1. "+T[0]+"\n"+"2. "+T[1]+"\n"+"3. "+T[2]+"\n"+"4. "+T[3]")
The above solution works, however the number of posts will be variable so that's not a viable solution.
What can I do to send the message with the correct formatting knowing that the number of posts in the list will vary from time to time?
Using str.join and a comprehension using enumerate:
msg = po.msg("<b>Top Posts:</b>\n\n" + '\n'.join(f'{n}. s {n}' for n, s in enumerate(T, 1)))
I am trying to create a Twitter bot that posts a random line from a text file. I have gone as far as generating the random lines, which print one at a time, and giving the bot access to my Twitter app, but I can't for the life of me figure out how to use a printed line as a status.
I am using Tweepy. My understanding is that I need to use api.update_status(status=X), but I don't know what X needs to be for the status to match the most recently printed line.
This is the relevant section of what I have so far:
from random import choice
x = 1
while True:
file = open('quotes.txt')
content = file.read()
lines = content.splitlines()
print(choice(lines))
api.update_status(status=(choice(lines)))
time.sleep(3600)
The bot is accessing Twitter no problem. It is currently posting another random quote generated by (choice(lines)), but I'd like it to match what prints immediately before.
I may not fully understand your question, but from the very top, where it says, "How to use the most recently printed line as an input", I think I can answer that. Whenever you use the print() command, store the argument into a string variable that overwrites its last value. Then it saves the last printed value.
Instead of directly printing a choice:
print(choice(lines))
create a new variable and use it in your print() and your api.update_status():
selected_quote = choice(lines)
print(selected_quote)
api.update_status(status=selected_quote)

So I am trying to get into python, and am using other examples that I find online to understand certain functions better.
I found a post online that shared a way to check prices on an item through CamelCamelCamel.
They had it set to request from a specific url, so I decided to change it to userinput instead.
How can I just simply loop this function?
It runs fine afaik once, but after the inital process i get 'Process finished with exit code 0', which isn't necessarily a problem.
For the script to perform how I would like it to. It would be nice if there was a break from maybe, 'quit' or something, but after it processes the URL that was given, I would like it to request for a new URL.
Im sure theres a way to check for a specific url, IE this should only work for Camelcamelcamel, so to limit to only that domain.
Im more familiar with Batch, and have kinda gotten away with using batch to run my python files to circumvent what I dont understand.
Personally if I could . . .
I would just mark the funct as 'top:'
and put goto top at the bottom of the script.
from bs4 import BeautifulSoup
import requests
print("Enter CamelCamelCamel Link: ")
plink = input("")
headers = {'User-Agent': 'Mozilla/5.0'}
r = requests.get(plink,headers=headers)
data = r.text
soup = BeautifulSoup(data,'html.parser')
table_data = soup.select('table.product_pane tbody tr td')
hprice = table_data[1].string
hdate = table_data[2].string
lprice = table_data[7].string
ldate = table_data[8].string
print ('High price-',hprice)
print ("[H-Date]", hdate)
print ('---------------')
print ('Low price-',lprice)
print ("[L-Date]", ldate)
Also how could I find the difference from the date I obtain from either hdate or ldate, from today/now. How the dates I parsed they're strings and I got. TypeError: unsupported operand type(s) for +=: 'int' and 'str'.
This is really just for learning, any example works, It doesnt have to be that site in specific.
In Python, you have access to several different types of looping control structures, including:
while statements
while (condition) # Will execute until condition is no longer True (or until break is called)
<statements to execute while looping>
for statements
for i in range(10) # Will execute 10 times (or until break is called)
<statements to execute while looping>
Each one has its strengths and weaknesses, and the documentation at Python.org is very thorough but easy to assimilate.

ntp client in python

Python Getting date online?
(9 answers)
Closed 5 years ago.
This should be a very simple task, but after 2 hours of searching and reading documents I failed to find a way to check the date and time from the internet using bash or python without installing anything extra like ntplib.
I am basically looking for an equivalent of pythons now() or bash $ date, but using an NTP (or any other way) to get the correct date and time from the internet. All the methods I find (such as ntpd) are meant to correct the system time, which is not my purpose.
Easy way to get the correct time in python
import time
import os
try:
import ntplib
client = ntplib.NTPClient()
response = client.request('pool.ntp.org')
os.system('date ' + time.strftime('%m%d%H%M%Y.%S',time.localtime(response.tx_time)))
except:
print('Could not sync with time server.')
print('Done.')
So I'm trying to learn Python here, and would appreciate any help you guys could give me. I've written a bit of code that asks one of my favorite websites for some information, and the api call returns an answer in a dictionary. In this dictionary is a list. In that list is a dictionary. This seems crazy to me, but hell, I'm a newbie.
I'm trying to assign the answers to variables, but always get various error messages depending on how I write my {},[], or (). Regardless, I can't get it to work. How do I read this return? Thanks in advance.
{
"answer":
[{"widgets":16,
"widgets_available":16,
"widgets_missing":7,
"widget_flatprice":"156",
"widget_averages":15,
"widget_cost":125,
"widget_profit":"31",
"widget":"90.59"}],
"result":true

Edited because I put in the wrong sample code.
You need to show your code, but the de-facto way of doing this is by using the requests module, like this:
import requests
url = 'http://www.example.com/api/v1/something'
r = requests.get(url)
data = r.json() # converts the returned json into a Python dictionary
for item in data['answer']:
print(item['widgets'])
Assuming that you are not using the requests library (see Burhan's answer), you would use the json module like so:
data = '{"answer":
[{"widgets":16,
"widgets_available":16,
"widgets_missing":7,
"widget_flatprice":"156",
"widget_averages":15,
"widget_cost":125,
"widget_profit":"31",
"widget":"90.59"}],
"result":true}'
import json
data = json.loads(data)
# Now you can use it as you wish
data['answer'] # and so on...
First I will mention that to access a dictionary value you need to use ["key"] and not {}. see here an Python dictionary syntax.
Here is a step by step walkthrough on how to build and access a similar data structure:
First create the main dictionary:
t1 = {"a":0, "b":1}
you can access each element by:
t1["a"] # it'll return a 0
Now lets add the internal list:
t1["a"] = ["x",7,3.14]
and access it using:
t1["a"][2] # it'll return 3.14
Now creating the internal dictionary:
t1["a"][2] = {'w1':7,'w2':8,'w3':9}
And access:
t1["a"][2]['w3'] # it'll return 9
Hope it helped you.
