There are three functions to check whether a file is a Python source, listed here with increasing complexity: - has_python_ext() checks whether a file name ends in '.py[w]'. - look_like_python() checks whether the file is not binary and either has the '.py[w]' extension or the first line contains the word 'python'. - can_be_compiled() checks whether the file can be compiled by compile(). The file also must be of appropriate size - not bigger than a megabyte. walk_python_files() recursively lists all Python files under the given directories.
