I'm making this as short as possible.
Requirements:
pip install Flask
Implementation:
1. In your project root dir create: A file named app.py
2. In your project root dir create:
A folder named "templates" and inside a file named "index.html"
index.html
<html lang="en">
<head>
<title>Flask Basic Example</title>
</head>
<body>
<h1>Flask Post: {{ text_to_show }}</h1>
<form action="/" method="POST">
<input type="text" name="content" />
<input type="submit" />
</form>
</body></html>app.py
from flask import Flask, render_template, request
app = Flask(__name__)
@app.route("/", methods=['GET', 'POST'])
def index():
if request.method == 'POST':
user_input = request.form['content']
return render_template("index.html", text_to_show=user_input)
return render_template("index.html")
if __name__ == "__main__":
app.run(debug=True, port=5000)
How it's used: Run app.py and go to http://127.0.0.1:5000 in your browser. Type some input, press send and the server will update the HTML with your input in a HTML paragraph. The Internet is full of extensive guides and tutorials. Sometimes you just want a quick example.
