#Two Hour Python Hacker

2 hours from now we hope to have a small application on the cloud!

There are a number of things we want to accomplish today.

1. Install Python
2. use the REPL
3. Run our first program
4. Install a package - (Flask)
5. Uninstall a package
6. Install virtualenv
7. Install virtualenvwrapper or virtualenvwrapper-win
8. Create a virtual environment
9. Install flask and run our first app
10. Get access to an API
11. Create a webapp
12. Deploy

#Let's do this

Windows

Mac

The REPL stands for Read Evaluate Print Loop

Makes iterating and testing easy!

python

'>>>'

try these commands:

x = 2 + 2

print x

import this

More Practice

Use your favorite text editor. I'm using Visual Studio Code

beginnings.py

sentence = "Four score and seven years ago"
sentence_no_vowels = ""
for letter in sentence: 
    if letter not in "AEIOUaeiou":
        sentence_no_vowels = sentence_no_vowels + letter
         
print sentence_no_vowels

Python Packages are installed with pip

We'll install requests

pip -v

pip install requests

pip uninstall requests

pip install virtualenv

virtualenv wrappers make it easy to manage multiple environments and can make iterating on project easy.

Windows

Mac

mkvirtualenv helloworld

cd into root of project

setprojectdir .

deactivate

workon helloworld

Now we need flask for our first website!

pip install flask

Create our hello.py

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

if __name__ == "__main__":
    app.run()

SWEET!

python hello.py
 * Running on http://localhost:5000/

We'll start from a project I've already built:

GIT deploy! Same Guide as above
