Here, I wrote down two additional Regular Expressions for two formats of phone numbers. # Data Files # We provide two files for this assignment. phonenumber= "(516)111-2222" The book first goes over the fundamentals of coding and have instructions on how to install the Python Interpreter on your computer. >>> phonenumber= "516-111-2222" I need this result "04" PIC S9(03). We will use one of such classes, \d which matches any decimal digit. print("Valid phone number") Steps for converting a 10-digit phone number to its corresponding US number format: Import the python re package. It will output the custom message I created. Example: line = "hello 12 hi 89" Result: [12, 89] In this article, we show how to match a phone number in Python using regular expressions. The expression checks to see if there is an “x,” then the “\d{2,5}” must match the digits that are 2 to 5 numbers long. print("Invalid phone number") [a-zA-Z]{2,5}) — looks for the .web extensions (e.g. Viewed 15k times 8 \$\begingroup\$ I've been working on my own phone number extraction snippet of Regex code and I'd appreciate your feedback on it. And this is how we can match a phone number in Python using regular expressions. I was able to figure out by testing and doing some research on regular expression with examples. Still, there are many different ways you can write expression because the regular expression is universal. “\-\.” Also can contain dashes or periods in the username, 2. — Validating for the area code (must be the three-digit number), “\d{3}” matches if there are three digits, “|” creates a conditional statement where depending on the validation would either be “(\d{3}” or “{\d{3}\)”, “\s|” matches a single space character then output “-”, “|\.” matches a period character then output “-”, 5. It was a short but fun project overall as I have learned a lot compared to the four years of college that I spent in a classroom. One of the projects that book wants us to work on is to create a data extractor program — where it grabs only the phone number and email address by copying all the text on a website to the clipboard. Regular expressions are a key concept in any programming language. Example import re s = '12345 abcdf 67' result=re.findall(r'\d', s) print result I have tested this with a random UK number and it did not output the correct phone number.
