取模运算的结果就是除法运算的余数,99/30=3余9所以99%3的结果就是9,==>没什么用就是表示个箭头,后面是这行程序运行的结果,#是注释,#后面的部分只会作为文本显示,不作为程序运行

额,,,,,短路计算,a and b 如果a是false 那么输出就是a 如果a是true 那么输出无论b是true或者false,都是b。你这里a=“pd”然后print(“hello”,a and “world”)a已经赋值字符串pd应该是true!

a='python'
print('hello',a and 'world') #==>hello, python
在and语句下,a值为true,所以运算结果取决于前者
b=''
print('hello',b or 'world') #==>hello, world
在or语句下,b值为false(空,0,None),所以运算结果取后者
print('hello',a and 'world') #==>hello, python

b=''
print('hello',b or 'world') #==>hello, world
