如何结束这个无限循环

Question

I have to sort a user inputed list from lowest to highest without . sort, but when I try to replace two values to put them in order I find myself in an infinite loop

list = input('Enter list of numbers separated by a space: ').split()
list = [int(b) for b in list]

def list_sort(list):
    while list:
        a = list[0]         # random number in list
        for x in list:      # to check every number in the list
            if x < a:       # find if the new number is less than original
                c, d = list.index(x), list.index(a)
                list[d], list[c] = list[c], list[d] 


print(list_sort(list))

Answer 1

You are setting your while loop to run as long as list is True, which in your code is always going to be true. What you want to do instead is set up a condition inside your while loop to break out of your loop with a break statement.

while True: 
 if some_break_condition_met:
     break
 else:
     # do logic

Also, list is used in python to create a list, so I strongly suggest not using list as your variable, maybe change it to lst or my_list. Using list could cause problems.

list = input('Enter list of numbers separated by a space: ').split(' ')
list = [int(b) for b in list]

def list_sort(list):
    updated = True
    while updated:
        updated = False
        for orig_index in range(0, len(list)):
            for check_index in range(orig_index, len(list)):      
                if list[check_index] < list[orig_index]:      
                    list[orig_index], list[check_index] = list[check_index], list[orig_index]
                    updated = True


print(list_sort(list))
