# python_count - count physical lines of code in Python programs.
# Usage: python_count [-f file] [list_of_files]
# file: file with a list of files to count (if "-", read list from stdin)
# list_of_files: list of files to count
# -f file or list_of_files can be used, or both
# This is a trivial/naive program.
# Comments begin with "#".
# Python supports multi-line strings using """, which matches another """.
# When not inside a multi-line string, a line whose first non-whitespace
# is """ almost always indicates a programming comment;
# this is also true for lines beginning with '"'
# This means that a string which is part of an expression but which begins
# a new line won't be counted; this problem is rare in practice.
# This code DOES count _data_ inside a triple-quote (that's not a comment).
# Note that this isn't true for single-quote, which is used in case
# statements (etc.) but not in this context.
# This is part of SLOCCount, a toolsuite that counts
# source lines of code (SLOC).
