Exercise 2

The following program identifies names used for both girls and boys and writes them to a file.

Complete the code to dissect lines to columns, so that the variables name and gender are defined.

girls = []
duplicates = []

for line in open('names/yob2015.txt'):

    # insert your code here

    if gender == 'F':
       girls.append(name)
    elif gender == 'M':
       if name in girls:
           duplicates.append(name)

output = open('duplicate_names.txt', 'w')
for name in duplicates:
    text = "{:>15s}\n".format(name)
    output.write(text)
output.close()
