变量名由大小写英文字母、数字和下划线_组成变量不能用数字开头变量尽量不要和Python关键字重合（比如前面学习过的：and、or、not，否则可能导致Python原有关键字发挥不出作用）

最容易理解的
def greet(param):
if param == None:
print('Hello World')
else:
print('Hello,{}'.format(param))
greet('Python')
def greet(param):
if param == None:
print('Hello World')
else:
print('Hello,{}'.format(param))
greet('Python')

在浏览器搜索python，进入官网，找到3.8版的，一定要按照电脑适配的位数，比如Windows64位就下载64位，Windows32位就下载32位。还有一个方法摁住Windows键再摁下R键，会在左下角弹出一个对话框，输入cmd或者python回车就可以了

根据短路运算原理，True or True进行运算时，在看到第一个True时就可以确定结果是True，不需要关注后面参与运算的是True还是False，所以只输出第一个True。
