Python打卡第二天

Note2

1. 输入一般格式  a=input(“输入:”)/print(“输入的内容是：”,a)
2. 当进行输入 *** 作时，无论什么情况，其输出格式都为字符型
3. 当需要把字符串变成数字时，可以强制类型转化，即加一个”int()”
4. “**”是返回x的y次幂，”//”是向下取接近除数的整数
5. Python指定任何非0和非空值为True,0或None为False
6. if后面的语句必须空格
7. 引入随即库”import random”/随机生成整数”x=random.randint(0,10)”

English version

1.The simple code of “input” is a=input(“input:”)/print(“the comment of input is ：”,a)

2.Whenever we need to perform input actions,the type of the output is str.

3.When we need to change str into number,we should force type conversion which is mains add “int”.

4.”**” mains return y power of x,and ”//”mains turn down an integer close to the divisor.

5.Any non-zero number and any non-null number is true,and 0 or None is False in python environment.

6.The statement after if must have space.

7.Introducing import random mains “import random”,and randomly generating integer mains “x=random.randint(0,10)”.
