Ironically, the first thing we’re going to do is show how to tell a computer to ignore a part of a program. Text written in a program but not run by the computer is called a comment. Python interprets anything after a
# as a comment.
Provide context for why something is written the way it is:
# This variable will be used to count the number of times anyone tweets the word persnickety persnickety_count = 0
Help other people reading the code understand it faster:
# This code will calculate the likelihood that it will rain tomorrow complicated_rain_calculation_for_tomorrow()
Ignore a line of code and see how a program will run without it:
# useful_value = old_sloppy_code() useful_value = new_clean_code()
Documentation is an important step in programming. Write a comment describing the first program you want to write!
