How to Use Python regex findall

The syntax for using the findall method is as follows:

import re

string = "This is a sample string for regex findall method."
pattern = "sample"

matches = re.findall(pattern, string)

print(matches) # Output: ['sample']

In this example, we imported the re module and defined our string and pattern variables. We then used the findall method to search for all occurrences of the pattern "sample" within the string.

The findall method can also be used with more complex patterns, such as regular expressions. For example:

import re

string = "This is a string with 123 and 456."
pattern = "d+"

matches = re.findall(pattern, string)

print(matches) # Output: ['123', '456']

In this example, we used the regular expression pattern "d+" to search for all occurrences of one or more digits within the string.

Conclusion

Python regex findall is a powerful search tool that can help you extract specific patterns from your text data. By learning how to use this method and regular expressions, you can efficiently manipulate and analyze your data with Python.
