boolean AND loop

Hi I've just start learning Python. Can someone help me? I've tried to wrote a code for a boolean AND. I wrote this: a = int(input("\"a\": ")) b = int(input("\"b\": ")) x = a and b while x: if x == True: print("True") a = int(input("\"a\": ")) b = int(input("\"b\": ")) x = a and b else: print("False") a = int(input("\"a\": ")) b = int(input("\"b\": ")) x = a and b When the and statement is True while loop is OK and i can type a,b values again. But when the statement is False it prints nothing and just ends the program. What i did wrong?

because when you write while x: your code is gonna run according to x, so, if x is true while loop is gonna run if x is false it s gonna continue its road without entering while loops block

When it ends it's already not gonna print anything because else statement is working in while loop, so its just gonna print something while "while loop" is running

So how I can code this? I want to run the program again and again even when the a and b will be False.

write while true: and test the x, i mean while true: //we're putting codes in it to get loop forever if x: //do something else: //do something if you couldnt understand i can try to explain better note: you can write x instead of x==true

So I modified the code with your instructions and now it works. a = int(input("\"a\": ")) b = int(input("\"b\": ")) x = a and b while True: if x: print("True") a = int(input("\"a\": ")) b = int(input("\"b\": ")) x = a and b else: print("False") a = int(input("\"a\": ")) b = int(input("\"b\": ")) x = a and b Thanks @Mustafa K.. But could you explain me more why "while x:" was wrong?
