In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
[]: Creates a character set that matches any one of the characters inside the square brackets. +: Matches one or more occurrences of the preceding. When you arrange these different regex constructs into the concise pattern shown above, you can split your messy shopping list into useful substri...
Lists in Python are dynamic structures; you can add, remove, or sort lists "in place" using list manipulation techniques. The get the length of the list, you can use the len() function. To create a list and initialize with values, you can enclose the values in square brackets, ...
