Many programming languages, including Python, have a ternary conditional operator, which is most often used for conditional variable assignment. In Python, an assignment statement can make two variables equal, but because of the possibility of reassignment, they don’t have to stay that way: a = 5 b = a # after executing this line, a and b are now equal a = 3 # after executing this line, a and b are no longer equal. a = 3 b = 2 if a==5 and b>0: print('a is 5 and',b,'is greater than zero.')
