如何在python 3.x中使用string.replace（）

string.replace（）在python 3.x上已弃用。这样做的新方法是什么？

Answer 1

replace()是<class 'str'>python3中的一种方法：>>>&nbsp;'hello,&nbsp;world'.replace(',',&nbsp;':')'hello:&nbsp;world'

Answer 2

python 3中的replace（）方法简单地用于：a = "This is the island of istanbul"print (a.replace("is" , "was" , 3))#3 is the maximum replacement that can be done in the string#>>> Thwas was the wasland of istanbul# Last substring 'is' in istanbul is not replaced by was because maximum of 3 has already been reached
