IndentationError: unindent does not match any outer indentation level in python 3, idk the reason why

Question

number = 64
running = True

while running:
        guess = int(input("write the number :"))
    if guess == number:
            print("Congrads! You won!")
            running = False
    elif guess < number:
        print("No, the number is a bit bigger")
    else:
        print("No, the number is less")
else:
    print("while cycle is over.")
else:
    print("end")

i expected a working code, but there's bugs i can't see, it says the problem in line four, but again, i can't see nothing wrong with it

Answer 1

In addition to G. Anderson you have following errors in the code (look comments):

number = 64
running = True

while running:
        guess = int(input("write the number :")) # <-- is indented too much
    if guess == number:
            print("Congrads! You won!") # <-- also indented "two tabs"
            running = False # <-- also indented "two tabs"
    elif guess < number:
        print("No, the number is a bit bigger")
    else:
        print("No, the number is less")
else:
    print("while cycle is over.")
else: # <-- second else?
    print("end")

This would be a fix:

number = 64
running = True

while running:
    guess = int(input("write the number :"))
    if guess == number:
        print("Congrads! You won!")
        running = False
    elif guess < number:
        print("No, the number is a bit bigger")
    else:
        print("No, the number is less")
else:
    print("while cycle is over.")
