要删除所有类型的空白字符,请使用str.translate:

>>> from string import whitespace
>>> s = "TN 81   NZ\t\t0025\nfoo"
# Python 2
>>> s.translate(None, whitespace)
'TN81NZ0025foo'
# Python 3
>>> s.translate(dict.fromkeys(map(ord, whitespace)))
'TN81NZ0025foo'

或者每个空格字符(包括\t\n)都带有正则表达式:

>>> re.sub(r'\s+', '', "TN 81 NZ 0025")
'TN81NZ0025'
>>> re.sub(r'\s+', '', "TN 81 NZ\t0025")  # Note the \t character here
'TN81NZ0025'
