Quick start to cleaning text data

What	How
Fix Unicode encoding errors	import ftfy ftfy.fix_text('✔ No problems')
Remove specific words	s = s.replace("foo", "")
Remove punctuation	import string s = s.translate(str.maketrans('', '', string.punctuation))
Remove hyperlinks	import re s = re.sub(r"https?://\S+", "", s)

# Solutions

sumTotal = 42 # Valid

# sum-total = 42 # Invalid. Dashes are a no-no.
sum_total = 42

# sum total = 42 # Invalid. Spaces are a no-no. White space is often meaningful in Python.
sum_total = 42

Find out if each of the following is either an acceptable or not acceptable Python identifier.

Do this by trying to assign them as an identifier for a variable. If you get a SyntaxError: can't assign to operator, fix the error by changing the identifier.

- sumTotal 
- sumtotal
- sum-total 
- sum total

Techniques to improve as a programmer

Do not be the person who has practiced 10,000 things once, but be the person who has practiced one thing 10,000 times.
— Intentionally misquoting Bruce Lee

1. Write a lot of code. Physically type code and run it (if either part is missing, it is not quality code practice).
2. Think of coding practice as a portfolio. It should be a mix:
   • 40-60% Easy-for-you fundamentals. Practicing Pythonic idioms to solve common atomic problems. This develops fluency to solve novel challenges and build up to more advanced coding.

• 20-30% Difficult-but-possible problems. LeetCode and similar is good for this level.
