Python的正則表達式的代碼

讓email.body =

> From: "FastTech" <[email protected]> 
> 
> == Ship to == 
> Example Name 
> 
> Shipping via Registered Airmail w/Tracking 
> 
> == Shipping ETA == 
> 
> == Items ordered == 
> 
> == Other services == 
> 
> 
> == Order total == 
> $2.63 
> 
> 
> 
> 
> Thank you again for choosing FastTech. 
> 
> Kind regards,

> [email protected]

我不能得到這個在我的劇本的工作 - 使用此代碼：

regex = r'> == Ship to == *\n. (\w+\s\w+)' 
    link = re.findall(regex, email.body) 
    print link

打印鏈接只是返回

[]

當它應該是匹配的 '實例名稱'

您的問題在於email.body。正則表達式工作正常。嘗試打印email.body。看到它的真實價值 – 2014-10-07 10:19:46

你的正則表達式工作正常，我。

>>> import re 
>>> s = """> From: "FastTech" <[email protected]> 
... > 
... > == Ship to == 
... > Example Name 
... > 
... > Shipping via Registered Airmail w/Tracking 
... > 
... > == Shipping ETA == 
... > 
... > == Items ordered == 
... > 
... > == Other services == 
... > 
... > 
... > == Order total == 
... > $2.63 
... > 
... > 
... > 
... > 
... > Thank you again for choosing FastTech.

>>> m = re.findall(r'> == Ship to == *\n. (\w+\s\w+)', s) 
>>> m 
['Example Name']

你可以試試這個。單個空間將完全匹配\s*將匹配零個或多個空格的空間。所以最好使用\s*而不是空格。

>>> m = re.findall(r'^\s*>\s*==\s*Ship\s*to\s*==\s+>\s*(\w+\s\w+)', s, re.M) 
>>> m 
['Example Name']

這有效......爲什麼不是我的？感謝您的答案:-)這是我第一次嘗試正則表達式.. – Andy 2014-10-07 10:24:19

@安迪它可能或可能不包含一個或多個空間..你總是歡迎:-) – 2014-10-07 10:28:54
