from flask import Flask, request
from pyhtml import html # TODO add imports
app = Flask(__name__)
@app.route('/', methods=["GET", "POST"])
def homepage():
if request.method == 'POST':
# TODO you received form data, handle it
# (usually produce HTML)
else:
# TODO you didn't receive form data
# (usually produce HTML)
response = html(
# TODO put your pyhtml code here
)
return str(response)
if __name__ == "__main__":
app.run(debug=True)
from flask import Flask
app = Flask(__name__)
@app.route('/')
def homepage():
return "Hello World!"
if __name__ == "__main__":
app.run(debug=True)
if __name__ == "__main__":
def homepage():
return "Hello World!"
from flask import Flask
app = Flask(__name__)
app.run(debug=True)
These allow us to use the Flask framework to do a lot of "behind the scenes" work.
@app.route('/') we need to add a few more routes.from flask import Flask
app = Flask(__name__)
@app.route('/')
def homepage():
return "Hello World!"
@app.route('/another_route')
def some_other_function():
return "This is the webpage associated "+ \
"with <code>another_route</code>."
@app.route('/list_desserts')
def desserts():
return "Cake, Popcorn, Brownies"
if __name__ == "__main__":
app.run(debug=True)
# import Flask
from flask import Flask
# create the Flask app
app = Flask(__name__)
# declare a route and link it to a function
@app.route('/')
def homepage():
# return HTML from the function --> this will show up when that route is navigated to
return "Hello World!"
# if this file has been run, then run the Flask app
if __name__ == "__main__":
app.run(debug=True)
3 + 4 or 7 * 8.form(action="destination_route")(
# Other form elements
input_(type="submit", value="Go")
)
submit is clicked, it will go to the destination_route function.@app.route('/destination_route')
Or
@app.route('/destination_route', methods=["GET"])
@app.route('/destination_route', methods=["GET", "POST"])
@app.route('/destination_route', methods=["POST"])
from flask import Flask, request
if request.method == 'POST':
name field of our form element.my_variable = request.form['field_name']
Now go take a look at your project starter code.
Does it make sense?
