Why do I get a RecursionError using either while or if indefinite loops

I want to make a while loop that runs indefinitely until a condition is true. The problem is when the condition isn't true the loop only runs for around two minutes and then breaks return the following error: RecursionError: maximum recursion depth exceeded in comparison

I have tried both of the following loops:

def loop():
    list = ['Lorem ipsum']
    n = 10
    list_length = len(list)
    while True:
        len(list) != n
        if len(list) == n:
            print('Lorem ipsum') 
            #This when I want to call main() and keep the loop running
            main()
        else:
            #I here make a call to another function
            def Lorem ipsum()
            #Or break out of the loop and run some code and return something
            break
    print('Lorem ipsum')
    return list_length

def loop():
    list = ['Lorem ipsum']
    n = 10
    list_length = len(list)
    if list_length != n:
        print('Lorem ipsum')
        return list_length
    else:
        print('Lorem ipsum')
        main()
