How the Python or Operator Works. With the Boolean OR operator, you can connect two Boolean expressions into one compound expression. At least one subexpressions must be true for the compound expression to be considered true, and it doesn’t matter which. If both subexpressions are false, then the expression is false.Learning.

This // operator divides the first number by the second number and rounds the result down to the nearest integer (or whole number). In this article, I will show you how to use the // operator and compare it to regular division so you can see how it works. Python offers different primitive operations based on regular expressions: re.match() checks for a match only at the beginning of the string. re.search() checks for a match anywhere in the string (this is what Perl does by default) re.fullmatch() checks for entire string to be a match.
