# Code Bites PY3 Class Notes Day 1

A basic over view of variable types. I haven't even installed Python yet and my brain is so tired.

I'm trying my best not to skip ahead and follow everything in order, but haveing programmed in FORTRAN, COBAL, PHP, JavaScript, LightScript, BasicA, QBasic, Visual Basic and others... the first few days are going to be like pulling teeth.

Overall, Python seems a lot easier than most of the other languages I've scrambled through (looking at you, C#) and it's easy see why it is getting so popular.

I'm not sure if I'll drop jQuery for Python, but PHP needs to watch its back.

Class Notes Day 1.5

Adding in a short little file here to remember that I can format text with Python.

``````
# Quick Password Test Putting this here so I don't forget
name = input("User Name: ")
passw = input("Password: ")
passl = len(passw)
passx = '\$' * passl
print ('----------')
print(f'Welcome {name}\nyour password is {passx} \n\tand it is {passl} characters long.')
