To find IPv4 addresses in a string using regex in Python, we can use the re
module in Python. We can define a regex pattern to search for IPv4 addresses and use the re
module's findall
method to find all matches in a given input string.
Here is an example code snippet that demonstrates how to find IPv4 addresses in a string using regex in Python:
main.py276 chars10 lines
In this example, we define a regex pattern ipv4_pattern
that matches IPv4 addresses in the string. The pattern \d{1,3}
matches 1-3 digits, and (?:\d{1,3}\.){3}
matches this pattern three times followed by a final match of \d{1,3}
. The \b
at the beginning and end of the pattern specifies that the match must occur at a word boundary.
We then use the re.findall
method to find all matches of this pattern in the input string, which gives us a list of IPv4 addresses found in the string.
