Every single code project that you will touch in your career will contain control flow statements such as while and if. A control flow statement requires Boolean logic to determine the program’s execution.
Basics of Boolean Logic
The basics of Boolean logic are simple.
- 1) The expression
x and yis
True, if both
- 2) The expression
x or yis
True, if at least one of the two variables is
- 3) The expression
True, if x is
- 4) The expression
a and b or cis the same as
(a and b) or cmeaning that “and” evaluates before “or”.
These four rules are enough to solve the following puzzle about Boolean operators: Can you solve it?

I scraped this puzzle’s data from Reddit’s most influential users:
# Influential reddit users # in million karmas way_fairer = 2.7 StickleyMan = 2.3 _vargas_ = 2.3 smeeee = 1.3 a = way_fairer > StickleyMan b = StickleyMan < smeeee and a c = _vargas_ >= StickleyMan c = a and b or c and smeeee > 1.2 d = not ((a and b) or c) if c and a: print(d) else: print(not d)
