You can achieve this by using the re.sub() function in Python. Here's an example of how you can replace a substring with a regex pattern:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
import re # Define the string text = "Hello, World!" # Define the regex pattern to match the substring you want to replace pattern = "World" # Define the regex pattern you want to replace with replacement = "Universe" # Use the re.sub() function to replace the substring with the regex pattern new_text = re.sub(pattern, replacement, text) # Print the new text print(new_text) |
In this example, the output would be:
1
|
Hello, Universe! |
You can also use more complex regex patterns for both the substring to replace and the replacement pattern. Just make sure to properly escape any special characters in the regex patterns.
