在單詞開始的正則表達式分裂性格

Question

我又試圖找出如何分割Python中的字符串，它具有以下類型格式的結尾：

'aaaa bbbb cccc:dd eeee:ff ggg hhhh iiii:jjjj kkkk:llll:mm nnn:ooo pppp qqqq:rrr' 

爲以下列表項：

'aaaa bbbb' 
'cccc:dd' 
'eeee:ff ggg hhhh' 
'iiii:jjjj' 
'kkkk: 
'llll:mm' 
'nnn:ooo pppp' 
'qqqq:rrr' 

我期待在以冒號結尾的單詞開始分裂（「：」）

任何建議，將不勝感激:)

Answer 1

爲提供例如以下工作：

import re 

string = 'aaaa bbbb cccc:dd eeee:ff ggg hhhh iiii:jjjj kkkk:llll:mm nnn:ooo pppp qqqq:rrr' 
result = [] 

# split the string at each word followed by a colon 
# wrap regex pattern as group so it is added to result list 
parts = re.split("(\w+:)", string) 

# if anything was previous to first delimitation token 
# add it to results 
if parts[0]: 
    result.append(parts[0].strip()) 

# create pairs of a delimitation token and next string 
# start from first delimitation token (list index 1) 
groups = zip(*[parts[i+1::2] for i in range(2)]) 

# join each pair to one string and strip spacing 
result.extend(["".join(group).strip() for group in groups]) 

print(result)
