Regular Expressions
Chapter 2: Regular expression basics
Matching patterns
Let’s start by searching for an exact string.
In our example, we want to search for "morning" in the string "morning josiah". Here is how you do this is Python, with the match() function in the re module.
>>> greeting = "morning josiah"
>>> query = "morning"
>>> match = re.match(query, greeting)
>>> print(match)
<re.Match object; span=(0, 7), match='morning'>
As you can see, the match object returns a Match instance with stores different attributes like the matched string and the location of the match. We will talk about the Match class later - let’s concentrate on regular expressions itself first!
