What Python Looks Like

Python code is famously easy to read. It has even been described half-jokingly as “executable pseudocode.” For example, you can probably understand a lot of the following program, even if you have no Python experience at all:

just_enough_python/find_prime_numbers.py

# Import the square root function
from math import sqrt


# Return True if the argument is a prime number, False otherwise
def is_prime(n):
    # n is prime if it cannot be divided evenly by any number in
    # the range from 2 to the square root of n.
    max_check_value = sqrt(n)
    # range(a, b) goes from a included to b excluded. Both a and b
    # must be integers, so we convert max_check_value to an integer
    # with the in-built int() ...
