def count_number_of_lines():
    with open('/cxldata/datasets/project/mbox-short.txt') as f:
        count = 0
        for line in f:
            line = line.rstrip() # Remove new line characters from right
            if line.startswith('Subject:'):
                count = count + 1
    return count

still why I am getting the error that name count_number_of_lines is not defined?
