To match a 10-digit number using regular expressions, you can use the following pattern:
^\d{10}$Example
Here's how you can use this regex pattern in Python:
import repattern = r'^\d{10}$'test_string = "1234567890"if re.match(pattern, test_string):print("Valid 10-digit number")else:print("Invalid number")Explanation
^ asserts the position at the start of the string.
\d matches any digit (equivalent to [0-9]).
{10} specifies that the previous token (a digit) must occur exactly 10 times.
$ asserts the position at the end of the string.
This regex ensures that the string contains exactly 10 digits and nothing else1.
Important Considerations
Limitations: This regex does not account for spaces, hyphens, or other delimiters. It strictly matches a sequence of 10 digits.
Alternative Solutions: If you need to match phone numbers with different formats (e.g., with spaces or hyphens), you might need a more complex regex pattern.
