用于str.translate从字符串中删除字符.

在Python 2.x中:

# first arg is translation table, second arg is characters to delete
strp = line.translate(None, punc)

在Python 3中:

# translation table maps code points to replacements, or None to delete
transtable = {ord(c): None for c in punc}
strp = line.translate(transtable)

或者,您可以使用str.maketrans以构建transtable:

# first and second arg are matching translated values, third arg (optional) is the characters to delete
transtable = str.maketrans('', '', punc)
strp = line.translate(transtable)
