开一个Python项目网络实践贴贴吧
本帖最后由 itubay 于 2024-6-19 20:04 编辑现在Python很流行，有网络交流的没有:handshake
Python中文指南
#Python项目源码hello.py
print("Hello，Python")
#命令行执行 python hello.py，前提是你要安装Python环境
#windows安装包
在线Python，打开WebShell直接敲代码
https://www.python.org/shell/
#web hello,wh.py
from flask import Flask
app=Flask(__name__)
@app.route("/")
def hello_world():
return "Hello World!"
if __name__=="__main__":
app.run()
#命令行执行python wh.py，然后打开指定网址
#getwip.py，获取公网ip
import requests
gip = requests.get("http://myip.ipip.net",timeout=5).text
print(gip)
#命令行执行python getwip.py即可 #listsyspath.py，列出系统目录
import os,sys
spath=sys.path
for path in sys.path:
if os.path.isfile(path):
print(path)
if os.path.isdir(path):
for file inos.listdir(path):
print(file)
#命令行执行 python listsyspath.py
#time.py，查询当前时间
import time
print("返回当前时间戳:",time.time())
print("返回当前时间:",time.ctime())
print("返回当前时间:",time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()))
print("返回当前时间:",time.strftime("%Y-%m-%d %X", time.localtime()))
#命令行执行 python time.py
#getmtime.py
import time
import calendar
dt=time.localtime(time.time())
print("当前时间:",time.strftime("%Y-%m-%d %X", dt))
_,days=calendar.monthrange(dt.tm_year,dt.tm_mon)
print("本月天数:",days)
#命令行执行 python getmtime.py
#pystumis.py，学生管理系统
