python从列表中逐个替换单词

Question

我是python的新手。我有一个列表car = [skoda,audi,benz]。我需要将这些单词逐个替换为文本文件，无论我在哪里找到car="mycar"/ vehicle="myvehicle"

请帮助，我们将不胜感激。 考虑我有一个文本文件：

I have a car="mycar" 
My friend has a vehicle="myvehicle" 
My uncle have a car="mycar" 

我需要更换汽车的列表的文本文件，并得到以下结果为：

I have a car="skoda" 
My friend has a vehicle="audi" 
My uncle have a car="benz" 

Answer 1

结合re.sub与itertools.cycle：

import re, itertools 

car = ['skoda', 'audi', 'benz'] 

text = """ 
I have a car="mycar" 
My friend has a vehicle="myvehicle" 
My uncle have a car="mycar" 

Second verse same as the first 

I have a car="mycar" 
My friend has a vehicle="myvehicle" 
My uncle have a car="mycar" 
""" 

it = itertools.cycle(car) 
newtext = re.sub(r'mycar|myvehicle', lambda _: next(it), text)
