In the previоus functiоn, yоu pаss а filenаme to a function; in this question you write that function. It will open the file to read its content. You are not allowed to import any package or library for this. Assume the data in a text file (text not CSV), looks like this (i.e. data on a line is separated by a comma): Row, Email, Name, Phone number Where Row is the key and the values are the rest of the row data as a list. Apply regex filter to check for valid emails and US phone numbers (US phone numbers are in the format xxx xxx xxxx). If an email is invalid, skip the entry. If the phone number is invalid, use the entry "invalid phone" instead but process the entry. Return the dictionary at the end.
