How to write conditional statements in python 02: Simultaneous judgment and simple statement groups

In the previous article, we explained the single condition and multiple conditions in the conditional statement. In today's article, we will explain the remaining situations in python conditional statements.

If the judgment requires multiple conditions and needs to be judged at the same time, you can use or (or), which means that the judgment condition is successful when one of the two conditions is true; when using and (and), it means that only two The judgment condition is successful only when the conditions are met at the same time. Examples of simultaneous judgments are as follows:

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
num = 9
if num >= 0 and num <= 10:    # 判断值是否在0~10之间
    print &#39;hello&#39;
# 输出结果: hello
 
num = 10
if num < 0 or num > 10:    # 判断值是否在小于0或大于10
    print &#39;hello&#39;
else:
    print &#39;undefine&#39;
# 输出结果: undefine
 
num = 8
# 判断值是否在0~5或者10~15之间
if (num >= 0 and num <= 5) or (num >= 10 and num <= 15):    
    print &#39;hello&#39;
else:
    print &#39;undefine&#39;
# 输出结果: undefine

When if has multiple conditions, brackets can be used to distinguish the order of judgments. The judgments in brackets are executed first. In addition, and and or take precedence. The level is lower than > (greater than), d9d89593fca4369d79f2ed7345c783c3 (greater than), 2342cb0436bd835a7369fdb5de0d7456= (greater than or equal to), <= (less than or equal to). Relationship.)

#The above are the other two cases of Python's conditional statements. Combined with the two cases in the previous article, a total of four cases of Python's conditional statements were carried out. I hope the examples and explanations can be helpful to you who have just learned python and make it easier for you to learn python.
