x = 2 while x < 400: print(x) x = x ** 2 while True: print(x**2, end=" ") if x == 400: break x = x **

Question

Why this keeps printing and why doesn't accept break?

Answer 2

2 ** 2 ---> 4
4 ** 2 ---> 16
16 ** 2 ---> 256
256 ** 2 ---> 65536

When the first loop broke the x was 65536.

The second loop would break only if x == 400, but x were never equal to 400.
