区分双字符和单字符？

Answer 1

嗯，我对Python还不熟悉。 但希望这能奏效！！！你知道吗

    import re;
    val_display__counter1_rij= {};
    l = ['val_display__counter1_rij', 'val_display___counter1_rij','val.display__counter1_rij']  # list of variables to match
    for x in l:
       if "." not in x:
          article = re.sub(r'(?is)_', '.', x)
          if ".." in article:
              article= article.replace("..","__");

          if (article == 'val.display__counter1.rij'):
              print(article)
