Understanding Python’s “pass” Keyword: A Practical Guide

The pass keyword in Python has no operational effect; it exists solely to occupy a place in the code so that the syntax remains correct and the program does not raise an error.

Example usage:

age = int(input("请输入你的年龄："))
if age > 16:
    # print("欢迎光临游戏城")
    pass
print("hello world")

When the user enters 20, the program outputs:

请输入你的年龄：20
hello world

This demonstrates that the pass statement does not affect program flow—it simply satisfies the requirement for a statement inside the if block, allowing the subsequent print to execute normally.
