To properly escape a question mark in a regular expression, you need to use a backslash before the question mark. This is because the question mark is a special character in regex that signifies that the preceding character is optional.
For example, if you want to search for the literal question mark character in a string, you would need to use the following regex pattern:
?
This pattern tells the regex engine to match a literal question mark character.
Here's an example of how you can use this pattern in Python:
1 2 3 4 5 6 7 8 |
import re text = "Is this a question?" pattern = r"?" matches = re.findall(pattern, text) print(matches) |
This code snippet will search the text for the question mark character and print out any matches found.
