Describe your issue in detail here.

Your code so far

def merge_sort(array):
    
    middle_point = len(array) // 2
    left_part = array[:middle_point]
    right_part = array[middle_point:]

    merge_sort(left_part)
    merge_sort(right_part)

    left_array_index = 0
    right_array_index = 0
    sorted_index = 0

    While True:
        if left_part < right_part:
            merge_sort(left_part)
            if left_array_index < len(left_part):
                pass
        else:
            merge_sort(right_part)
            if right_array_index < len(right_part):
                pass

Hi @abdoulayeaffadinebra

You have:

    While True:
        if left_part < right_part:
            merge_sort(left_part)
            if left_array_index < len(left_part):
                pass
        else:
            merge_sort(right_part)
            if right_array_index < len(right_part):
                pass

The request says:

Create two conditions for the loop:

I know that’s quite unambiguous but it expects you to understand that it is talking about the condition of the loop and not the content inside the loop block, which is what you have.
In other words:

while condition one and condition two:
    pass

Or in this case:

while something < something_else and another_something < another_else :
    pass

By the way, Python is case sensitive in its keywords, which means that While would not be the same than while

while needs to be lowercase
