以下是示例文本:
initiated to address the deviation to SOP-020583v11.0 Section SOP-016248v2.0 john doe, john doe SOP-020583 fake text, this is all fake
理想情况下,文本应如下所示:
initiated to address the deviation to 020583 Section 016248 john doe, john doe 020583 fake text, this is all fake
以下是我目前掌握的代码:
def dashrepl(matchobj):
print (type(matchobj))
return re.findall('[0-9]',matchobj)
re.sub(SOP, dashrepl, long_desc_text[22])
但我得到了以下错误:
TypeError: expected string or buffer
编辑更新内容:
long_desc_text[22]
SOP-020583v11.0 Section 8.4.On 17Jan2016 at ATO Site, SOP-016248v2.0 was due for periodic review but the periodic SOP-016248 revision is not tied to any change control records. SOP-020583 tied to a change control record" and notified ID63718 notifiedID22359 of the event. SOP-020583v11.0, fake text fake text
所以,这是我的密码:
它产生:
“着手解决020583第016248节的偏差,无名氏,无名氏020583假文本,这都是假的”
使用python的re函数“subn”查找并用指定的字符串替换模式的所有示例—在本例中是第一个捕获组。字符串前面的“r”将其指定为regex对象。你知道吗
作为参考,我还发现了这个link
希望这有帮助。你知道吗
