Jan 30, 2013 · Don't use while True and break statements. It's bad programming. Imagine you come to debug someone else's code and you see a while True on line 1 and then have to trawl your way through another 200 lines of code with 15 break statements in it, having to read umpteen lines of code for each one to work out what actually causes it to get to the break.
My code never goes out of the while loop even if the variable is assigned 1 or 2 or 3. Am I missing something here or doing something wrong? I never read any documentation about Python that said or statements wouldn't work in while loops. According to propositional calculus this should be correct because True or False or False = True
period=0. tmp=universe_array. while True: tmp=apply_rules(tmp)#aplly_rules is a another function. period+=1. if numpy.array_equal(tmp,universe_array) is True: break #i want the loop to stop and return 0 if the. #period is bigger than 12. if period>12: #i wrote this line to stop it..but seems it.
condition1 = False. condition2 = False. val = -1. #here is the function getstuff is not defined, i hope you define it before. #calling it into while loop code. while condition1 and condition2 is False and val == -1: #as you can see above , we can write that in a simplified syntax. val,something1,something2 = getstuff() if something1 == 10:
import time. t_end = time.time() + 60 * 15. while time.time() < t_end: # do whatever you do. This will run for 15 min x 60 s = 900 seconds. Function time.time returns the current time in seconds since 1st Jan 1970. The value is in floating point, so you can even use it with sub-second precision. In the beginning the value t_end is calculated to ...
Nov 1, 2012 · 193. The easiest way is to just interrupt it with the usual Ctrl-C (SIGINT). try: while True: do_something() except KeyboardInterrupt: pass. Since Ctrl-C causes KeyboardInterrupt to be raised, just catch it outside the loop and ignore it. edited Nov 1, 2012 at 16:18.
May 21, 2013 · exit([status]) Exit the interpreter by raising SystemExit(status). If the status is omitted or None, it defaults to zero (i.e., success). If the status is numeric, it will be used as the system exit status. If it is another kind of object, it will be printed and the system. exit status will be one (i.e., failure).
Aug 22, 2017 · Because of the attention, this post is attracting I thought it would be good to point out how this can be achieved with an infinite while loop as well. To use an infinite loop with tqdm you need to change your while loop into an infinite for loop by utilizing a generator. Infinite loop (no progress bar) while True: # Do stuff here
Apr 26, 2018 · 1. This is the right way to plot Dynamic real-time matplot plots animation using while loop. There is a medium article on that too: pip install celluloid # this will capture the image/animation. import matplotlib.pyplot as plt. import numpy as np. from celluloid import Camera # getting the camera.
Try the following: import time. timeout = time.time() + 60*5 # 5 minutes from now. while True: test = 0. if test == 5 or time.time() > timeout: break. test = test - 1. You may also want to add a short sleep here so this loop is not hogging CPU (for example time.sleep(1) at the beginning or end of the loop body).
