You should have a look at the csv module in python.

is_in_file = False
with open('my_file.csv', 'rb') as csvfile:
    my_content = csv.reader(csvfile, delimiter=',')
    for row in my_content:
        if username in row:
            is_in_file = True
print is_in_file

It assumes that your delimiter is a comma (replace with the your delimiter. Note that username must be defined previously. Also change the name of the file. The code loops through all the lines in the CSV file. row a list of string containing each element of your row. For example, if you have this in your CSV file: Joe,Peter,Michel the row will be ['Joe', 'Peter', 'Michel']. Then you can check if your username is in that list.
