OR operand in re module

In the "re" module, you can use the pipe character | to specify the OR operand in a regular expression. This allows you to match one pattern or another pattern.

Here's an example of using the OR operand in the "re" module in Python:

import re

text = "The quick brown fox jumps over the lazy dog."

pattern = "fox|dog" # Match "fox" or "dog"

# Use the findall() function to find all matches of the pattern in the text

matches = re.findall(pattern, text)

print("Matches:", matches)

In this example, we are using the OR operand to match either "fox" or "dog" in the given text. We are using the findall() function to find all occurrences of the pattern in the text, and then printing out the matches.

You can use the OR operand with any regular expression syntax, such as character classes, grouping with parentheses, and quantifiers. For example:

import re

text = "The quick brown fox jumps over the lazy dog."

pattern = "(fox|dog) \w+" # Match "fox" or "dog" followed by one or more word characters

# Use the findall() function to find all matches of the pattern in the text

matches = re.findall(pattern, text)

print("Matches:", matches)

In this example, we are using the OR operand with grouping to match either "fox" or "dog" followed by one or more word characters in the given text. We are using the findall() function to find all occurrences of the pattern in the text, and then printing out the matches.
