If the first condition isn't met, check the second condition, and if it’s met, execute the expression. Else, do something else.
In the form shown above: <expr> is an expression evaluated in a Boolean context, as discussed in the section on Logical Operators in the Operators and Expressions in Python tutorial. <statement> is a valid Python statement, which must be indented. (You will see why very soon.) If <expr> is true (evaluates to a value that is “truthy”), then <statement> is executed.
Python supports the usual logical conditions from mathematics: Equals: a == b. Not Equals: a != b. Less than: a < b. Less than or equal to: a <= b. Greater than: a > b. Greater than or equal to: a >= b. These conditions can be used in several ways, most commonly in "if statements" and loops. An "if statement" is written by using the if keyword.
