How to ask user 'Do You Want To Continue?' in python using while loop but not by calling functions

Question

[enter image description here][1]I'm new to this language, I'm not getting how should I ask user 'Do You Want To Continue?' using while loop but not calling the function inside this loop. For example:

do{
__some code here__
}while (ch == 'y')

I want this same in code python by without calling function

Please provide the code as you would write it with functions for reference. This smells like homework and like you didn't even research the basic syntax of the language. Anyhow, as a new user, please take the [tour] and read [ask]. — Ulrich Eckhardt, Jan 24 '19 at 19:32

`while True: a = input("Enter yes/no to continue") if a=="yes": gameplay() continue elif a=="no": break else: print("Enter either yes/no")` @UlrichEckhardt I have read this over stack overflow only, my query is to not to use function within a loop — Munna Michael, Jan 24 '19 at 20:01

Since Python has no do-while construct, the equivalent would be an infinite loop with a condition that breaks it:

while True:
    # some code here
    if input('Do You Want To Continue? ') != 'y':
        break

You can use input within the while statement condition check. Something like this:

while input("Do You Want To Continue? [y/n]") == "y":
    # do something
    print("doing something")

If you want to use that code, just indent the bottom 3 lines inside the while loop. – elahav Jan 24 '19 at 20:11
Thank You, I appreciate your help – Munna Michael Jan 24 '19 at 20:23

In your code, all you have to do is to indent the last 3 lines inside the outer while loop, like this...

endFlag = False

while endFlag == False:
    i, l = 10, []

    while i < 5:
        a = int(input('Sub Marks'))
        l.append(a)
        i += 1

    total = sum(l)
    print('Total is: ', total)

    per = total*0.25
    print('Percentage: ',per)

    ui = input("Would you like to repeat the program again? Y/N")
    endFlag = True if ui.lower() == 'n' else False

Besides that, I found some ways to improve your code, that's why I modified it
