Hello. I need help making these functions in Python.

• A function named check_number that takes a string parameter. The function will return true if the string consists of exactly a phone number in either the form xxx-xxxx or the form (xxx) xxx-xxxx. Yes, there is a space between the ) and the following number.
• Write code that reads a file name data.txt and writes to a file phones.txt only those lines from data.txt that are phone numbers. A line that contains a phone number and other things should not end up in phones.txt. Make sure you use your check_number function.
