Python去除String中的空格/换行/回车等

join:在序列中添加元素
split: 将字符串分解成序列
两者为互逆方法

    
    s = "as, asdas \r\nasda"
    print s.split();
#   result: ['as,', 'asdas', 'asda']

    print "".join(s.split());
#    result: as,asdasasda

    l = "".join(s.split()).split(',');
    print l;
#   result: ['as', 'asdasasda']
