如何在包含冒号的单词前插入换行符

Question

我有一个字符串，都是一行，比如：

Breed: Pembroke Welsh Corgi Price: $2,200 Gender: Female Nickname: Koko 
Age: 9 Weeks Old Color/Markings: yellow and white Size at Maturity: 
Medium Availability Date: 09/30/2018 Shipping Area: Worldwide Payment 
Method: Money Order/Cashier's Check, Paypal, Credit Cards, Cash

我希望输出是：

Breed: Pembroke Welsh Corgi
Price: $2,200
Gender: Female
Nickname: Koko

基本上在以冒号结尾的新类别前插入一个\n。你知道吗

感谢您提前回复！你知道吗

Answer 1

不可能将多个单词类别与执行它们的值区分开来，但是假设您可以将自己限制为单个单词类别，您可以使用以下内容：

import sys
data = "Breed: Pembroke Welsh Corgi Price: $2,200 Gender: Female Nickname: Koko"
words = data.split(' ')
for word in words:
    if word.endswith(':'):
        sys.stdout.write("\n"+word)
    else:
        sys.stdout.write(" "+word)
sys.stdout.write("\n")

产生输出：

Breed: Pembroke Welsh Corgi
Price: $2,200
Gender: Female
Nickname: Koko
