Very simple example of bottle and form input

server.py

import bottle

app = bottle.Bottle()
s = """<p>名前は？</p>
<p>
<form method="GET" action="/get"">
<input type="text" name="a" />
<input type="submit" />
</form>
</p>"""

t = """
<h1>{}さんこんばんは</h1>
"""


@app.route("/")
def root():
    return s


@app.route("/get")
def get():
    a = bottle.request.query.a
    return t.format(a)


app.run()
