python - 去除标点符号，输出剩余文本-Python 3 Function

Question

我想通过我的函数运行此文件，然后在删除整数或数字后输出剩余的文本。下面是我的Python代码:

theFile=open("home/filepath/file",'rt', encoding= 'latin-1').read()
words= the_file.split()

def replace_numbers(words):
    new_words=[]
    for word in words:
        new_word= re.sub(" \d+", " ", word)
        if new_word !='':
            new_words.append(new_word)
    return new_words

replace_numbers(words)

以下是文件中的一些示例文本:

soccerfif@yahoo.com 366-44-4444 Jezos was born Jeffrey Preston Jorgensen on January 12, 1964, also 5 and 4"

我希望输出是:

soccerfif@yahoo.com 366-44-4444 Jezos was born Jeffrey Preston Jorgensen on January 12, 1964, also and

所以基本上从文本文件中删除所有整数。简单。

有没有办法返回删除文件中所有数字然后输出剩下的结果。截至目前，输出只是[]。我知道问题可能出在 if new_word != '': 部分，但我似乎找不到问题。

Answer 1

如果您只想删除全部数字部分，您甚至不需要re。只需分割，然后保留所有不是数字的内容。

>>> text = "soccerfif@yahoo.com 366-44-4444 Jezos was born Jeffrey Preston Jorgensen on January 12, 1964, also 5 and 4"
>>> [word for word in text.split() if not word.isdigit()]
['soccerfif@yahoo.com', '366-44-4444', 'Jezos', 'was', 'born', 'Jeffrey', 'Preston', 'Jorgensen', 'on', 'January', '12,', '1964,', 'also', 'and']
>>> ' '.join(_)
'soccerfif@yahoo.com 366-44-4444 Jezos was born Jeffrey Preston Jorgensen on January 12, 1964, also and'
