把做工程过程重要的一些代码做个记录，下边代码内容是关于python使用Flask框架的简单入门范例的代码。
import os
# Using Flask since Python doesn't have built-in session management
from flask import Flask, session
app = Flask(__name__)
# Generate a secret random key for the session
app.secret_key = os.urandom(24)
@app.route('/')
def index():
return "Hello world"
if __name__ == '__main__':
app.run(
host="0.0.0.0",
port=int("80")
)
