The general form of the if statement in Python is as follows:

If condition_1: statement_block_1elif condition_2: statement_block_2else: statement_block_3

If "condition_1" is True, the "statement_block_1" block statement will be executed

If "condition_1" is False, "condition_2" will be judged.

If "condition_2" is True, the "statement_block_2" block statement will be executed

If "condition_2" is False, the "statement_block_3" block statement will be executed
