python的flask框架下实现在浏览器点一个按钮，页面跳到你自定义的其他页面

_init_.py

from flask import Flask, request, url_for, redirect, render_template

app = Flask(__name__)

@app.route(\'/\')
def index():
    return render_template(\'index.html\')

@app.route(\'/cool_form\', methods=[\'GET\', \'POST\'])
def cool_form():
    if request.method == \'POST\':
        # do stuff when the form is submitted

        # redirect to end the POST handling
        # the redirect can be to the same route or somewhere else
        return redirect(url_for(\'index\'))

    # show the form, it wasn\'t submitted
    return render_template(\'cool_form.html\')

index.html

<!doctype html>
<html>
<body>
    <p><a href="{{ url_for(\'cool_form\') }}">Check out this cool form!</a></p>
</body>
</html>

cool_form.html

<!doctype html>
<html>
<body>
    <form method="post">
        <button type="submit">Do it!</button>
    </form>
</html>

运行结果

进入5000端口显示如图，点击这个按钮，跳到自定义的/cool_form页面

在我的程序里我实现了在web页面点击加法器或者除法器按钮进入相应页面
