How to use 3 branches in Python?

In Python, you can use if statements to implement a three-way conditional judgment.

if condition1:
    # 如果condition1为真，执行这里的代码
    statement1
elif condition2:
    # 如果condition2为真，执行这里的代码
    statement2
else:
    # 如果condition1和condition2都为假，执行这里的代码
    statement3

In this case, condition1 and condition2 are two conditional expressions used to determine which branch of code to execute based on their truth value. statement1 and statement2 are code blocks that correspond to the branches, which can contain one or more statements. statement3 is the code block for the else branch, used to handle situations other than condition1 and condition2.

You can modify the conditional expressions and corresponding code blocks according to specific needs to achieve the desired three-branch logic.
