本文实例讲述了python格式化css文件的方法。分享给大家供大家参考。具体实现方法如下：
import string, sysimport re, stringiotab=4def format(ss): f = open (ss, r) data = f.read() f.close() dlen = len(data) i = 0 buf = stringio.stringio() start = 0 while i < dlen: if data[i] == '{': buf.write(data[start:i] + ' { ') i = i + 1 start = i elif data[i] == '}': last = string.strip(data[start:i]) if last: buf.write(' '*tab + last + ';') buf.write(' } ') i = i + 1 start = i elif data[i] == ';': line = string.strip(data[start:i]) buf.write(' '*tab + line + '; ') i = i + 1 start = i else: i = i + 1 buf.write(data[start:i+1]) return buf.getvalue()if __name__ == '__main__': if len(sys.argv) == 1: print 'usage: cssformat.py filename' sys.exit() ret = format(sys.argv[1]) print ret
希望本文所述对大家的python程序设计有所帮助。
