使用替换字符串数组

Question

我想执行以下操作：

thing = "hello world"
A = ["e","l"]
B = ["l","e"]
newthing = thing.replace(A,B)
print(newthing)

那么输出应该是 hleeo wored，但似乎不允许我使用数组替换作为输入。有没有办法还能这样呢？

Answer 1

这会起作用：

newthing = thing
for a,b in zip(A, B):
    newthing = newthing.replace(a, b)

Answer 2

这是我的想法。

thing = "hello world"
A = ["e","l"]
B = ["l","e"]

def replace_test(text, a, b):
    _thing = ''
    for s in text:
        if s in a:
            for i, val in enumerate(a):
                if s == val:
                    s = b[i]
                    break
        _thing += s
    return _thing

newthing = replace_test(thing, A, B) 
print(newthing)

#>> hleeo wored
