POParsing a python file to check it conforms to certain rules

copied!<p>My mentor Barry is always kicking me for forgetting to put spaces after my commas, equals signs, and for leaving too many lines at the end of a file. I wanted to practice some python and to write a parser to check my files before presenting them to him.</p> <pre><code>#BarryParser v0.1 from re import findall, search def comma_checker(line, lineno): """ Checks commas have a space after them """ split_line = line.split(', ') for string in split_line: found_error = findall('.*,.*', string) if found_error: print "BARRY ISSUE DETECTED: COMMA ERROR LINE: %s: %s" % (lineno, line) def equals_checker(line, lineno): split_line = line.split(' = ') for string in split_line: found_error = findall('.*==?.*', string) if found_error: print "BARRY ISSUE DETECTED: EQUALS ERROR LINE: %s: %s" % (lineno, line) def too_many_blank_lines(lines): """if the last line is a new line and the line before is also a new line, rasises barry issue over too many blank lines """ last_line = lines[len(lines)-1] second_to_last_line = lines[len(lines)-2] if last_line == "\n" and second_to_last_line == "\n": print "BARRY ISSUE DETECTED: TOO MANY BLANK LINES AT END OF TEXT" elif search('\t*\n{1}', last_line)and search('\t*\n{1}', second_to_last_line): print "BARRY ISSUE DETECTED: TOO MANY BLANK LINES AT END OF TEXT" elif search('\t*\n{1}', second_to_last_line) and last_line == "\n": print "BARRY ISSUE DETECTED: TOO MANY BLANK LINES AT END OF TEXT" def main(): file = open("test.txt") line_no = 0 lines = file.readlines(100000) too_many_blank_lines(lines) #CHECK FOR BLANK LINES AT END OF TEXT for line in lines: line_no +=1 if not line == "\n": if not line[:1] == "#": comma_checker(line, line_no) #CHECK COMMAS ARE DONE RIGHT equals_checker(line, line_no) #CHECK EQUALS HAVE SPACES AFTER & BEFORE if __name__ == '__main__': main() </code></pre> <p>It will be parsing python files. The question being, I can't figure out how to get the equals bit to handle == and = the same way. </p>

Querying!
