Flask hello.py basic app not running?
flask, python, virtualenv
Solution
Your file does not match the example in the documentation. You've placed the `if __name__ == '__main__':` block inside the definition of `hello()`.
Whitespace is significant in Python. It needs to be placed outside the function definition (i.e., aligned all the way to the left). Doing so will execute the `if` when the script is run. The way it exists now, you would need to import the `hello` module and call the `hello` function. That isn't what you want. Fix the indentation and you will be all set.
Problem
when I enter python hello.py in the command line, I get another bash prompt. I'm not sure what could be the problem since I'm able to run a virtualenv and when I check which version of flask I have the latest version, `>>> '0.10.1'` installed. ``` Opals-MacBook-Pro:~ opalkale$ cd myproject Opals-MacBook-Pro:myproject opalkale$ ls hello.py venv Opals-MacBook-Pro:myproject opalkale$ . venv/bin/activate (venv)Opals-MacBook-Pro:myproject opalkale$ python hello.py (venv)Opals-MacBook-Pro:myproject opalkale$ ``` The code for hello.py looks like: ``` from flask import Flask app = Flask(__name__) @app.route("/") def hello(): return "Hello World!" if __name__ == "__main__": app.run() ``` This code was taken from: http://flask.pocoo.org/docs/quickstart/#quickstart
