Boolean theory

Question

Hi👋
Can anyone tells me about what is boolean theory . For example in python we have True function and False function . How does boolean works and how does true and false works in programming languages like python ? And How can I use true and false in programs?

Answer 1

False is 0
True is 1
(True can be any value other than 0 though)
an example would be the infinite loop:

while True:
print("Hello")

# same as

while 1:
print("Hello")

We can use this to continuously loop through a set of commands and you can potentially have a check, and if that check succeeds, it could make it False and the loop stops.

running = True
while running:
word = input("Type a word (or 'q' to quit): ")
if word == 'q':
running = False
break
print("You typed:",word)
