When using ==, if the two items are the same, it will return True. Otherwise, it will return False. You can use = to assign values to variables.Single Underscore. Example 1: Single Underscore In Interpreter: _ returns the value of the last executed expression value in Python Prompt/Interpreter. Example 2: Single Underscore for ignoring values. Multiple times we do not want return values at that time to assign those values to Underscore.If statements with and+ or. To handle complex scenarios, our if statement can combine the andand oroperators together. That way we turn several conditions into code, of which some have to happen simultaneously (and) while others need just one to be True(or). When we code complex conditions, it’s a good idea to use parentheses ((and )).1. The ** operator will, internally, use an iterative function (same semantics as built-in pow() ( Python docs ), which likely means it just calls that function anyway). Therefore, if you know the power and can hardcode it, using 2*2*2 would likely be a little faster than 2**3.
