Python从入门到精通

一、使用IDEA创建Python项目

文件-新建-项目，语言选择Python，等待python解释器安装成功后即可

二、Python语法基础

import subprocess

subprocess.run("dir",shell=True,encoding='utf8')
print("hello")
name = "zhangsan"
#name:  zhangsan
print(f"name:  {name}")
#zhangsan
print(name)

name2 = "zhangsann"
#False
print(name == name2)

#从外部输入
high = input("please input high:")
print(f"high: {high}")

#False
print("A" == 65)
print("A"+"1")

#读取外部文件内容
try:
    with open("firsttxt.txt","r",encoding='utf-8') as f:
        content = f.read()
        print(content)
except FileNotFoundError:
    print("file not found")
finally:
    print("try end")

#条件判断
if 8 == 10:
    print(等于)
else:
    print("不等于")

#循环
for i in {1,2,3,4}:
    print(i)
