Feb 5, 2021 · A loop is the best way to achieve this. For example check out this pseudo code: While person is hungry Eat food a bite of food Increase amount of food in stomach If amount of food ate fills stomach person is no longer hungry stop eating food

Sep 13, 2015 · I have got one problem with Python. I'm trying to repeat a for loop more than once. I have a condition inside the loop, and if the condition is true, the loop should start again. I need the solution only with one for loop. For example: for i in range (10): if i==4: i=0 print(i) Unfortunately this doesn't work.

Dec 15, 2017 · A while loop continues as long as its condition is True, a repeat loop continues until its condition is True. @snr is wrong, but it's a common mistake. Compare: while must_continue: command and while True: command; if not must_continue: break .

May 28, 2012 · Basically, I ask a question and await an answer between two possibilities. If the given answer is not part of the two choices, I print a line and would like to re-ask the question until the correct input is given and then move on to the next question and repeat the same sequence. Here is a snippet of code to maybe better explain myself:

Jul 15, 2013 · continue - moves on to the next time around the loop without executing following code this time around; else - is executed if the loop completed without any break statements being executed. N.B. In the now unsupported Python 2 range produced a list of integers but you could use xrange to use an iterator. In Python 3 range returns an iterator.

Jan 31, 2012 · Use break to break out of the while loop: There is no need to test if answer is in ('yes',), since the while True loop will continue looping by default: answer in ('no') is the same as answer in 'no', which would only be True if answer is 'n' or 'o' or 'no'. That's probably not what you mean. Better to use answer == 'no'.

Sep 3, 2011 · if for some reason i want to repeat the same iteration how i can do it in python? for eachId in listOfIds: #assume here that eachId conatins 10 response = makeRequest(eachId) #assume that makeRequest function request to a url by using this id if response == 'market is closed': time.sleep(24*60*60) #sleep for one day

Sep 24, 2012 · When you're writing a standalone Python program, it’s a good practice to use a main function. it allows you to easily add some unit tests, use your functions or classes from other modules (if you import them), etc.

Jan 13, 2018 · To repeat something for a certain number of times, you may: Use range or xrange. for i in range(n): # do something here Use while. i = 0 while i < n: # do something here i += 1 If the loop variable i is irrelevant, you may use _ instead. for _ in range(n): # do something here _ = 0 while _ < n # do something here _ += 1

Every time I write a while loop where the variable that the condition checks is set inside the loop (so that you have to initialize that variable before the loop, like in your second example), it doesn't feel right. And then I search for python repeat until to remind myself that I …
