python入门基础代码初学

• 一、检查python安装
• 二、print使用
• 二、使用python运算
• 三、enumerate()函数

一、检查python安装

PS C:\\Users\\admin> python
Python 3.8.8 (tags/v3.8.8:024d805, Feb 19 2021, 13:18:16) [MSC v.1928 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

二、print使用

>>> print ("hello,the linux is a good system")
hello,the linux is a good system

PS C:\\Users\\admin> python C:\\Users\\admin\\Desktop\\hello.py
hello ,world

二、使用python运算

PS C:\\Users\\admin> python.exe
Python 3.8.8 (tags/v3.8.8:024d805, Feb 19 2021, 13:18:16) [MSC v.1928 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> a=1454
>>> b=145878
>>> a*b
212106612
>>>

三、enumerate()函数

>>> student = [ 'name', 'sex', 'class', 'weight', 'height', 'interest' ]
>>> list(enumerate(student))
[(0, 'name'), (1, 'sex'), (2, 'class'), (3, 'weight'), (4, 'height'), (5, 'interest')]

>>> for i in student:
...        print(i)
...
name
sex
class
weight
height
interest
