How to limit list of string is pattern with regex?

@mac 

To limit a list of strings based on a specific pattern using regex, you can use the re module in Python. Here's an example code snippet to demonstrate this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

import re

# Sample list of strings
string_list = ["apple", "banana", "peach", "1234", "grape123"]

# Define the regex pattern to filter the strings
pattern = r'^[a-z]+$'

# Use list comprehension to filter the strings based on the pattern
filtered_list = [s for s in string_list if re.match(pattern, s)]

# Print the filtered list
print(filtered_list)

In this code snippet, the pattern variable represents the regex pattern that only allows lowercase alphabetical characters. You can modify the pattern according to your specific requirements. The re.match() function is used to check if a string matches the pattern. The resulting filtered_list will only contain strings that match the specified pattern.
