Three short scripts produced by the attendees of #PyPool (Python meet-up in Liverpool, UK). These three pieces of code were used as a guide / introduction to Python for those new to the programming language to assist them in grasping the foundations of the language and syntax

(Week 1) love.py

Wasn't able to make it to the meetup but having a Python group in Liverpool is really cool and I hope to make future ones!

Not sure if this came up but if you've worked with sets before, Python has nice implementations of basic set operations which could have been used in love.py:

# People with "x" in their name are awesome
if "x" in set(p1) | set(p2): # union operator
    score += 1

# Number of common chars
for c in set(p1) & set(p2): # intersection operator
    score += 2

# Vowels are cool
vowels = 'aeiou'
for c in set(vowels) & set(p1) & set(p2):
    score += 1

# No, really, we like vowels
def vowelscheck(p):
    vowelsmissing = 0
    for c in set(vowels) - set(p): # difference operator
        vowelsmissing += 0.2
    return vowelsmissing
