我需要比较两个字符串并删除字符串1（python）中匹配的字符

Question

我有两个字符串，例如： string1 = "abcdefga"string2 = "acd" 我需要用"befga"返回stringone 我可以替换它，但是如果string1有两个相同的字符，它就会去掉这两个字符，因此例如，我的string1继续返回为"befg”：

for char in string1:
    for nike in string2:
        if char == nike:
            string1 = string1.replace(char,"")

Answer 1

您可以使用replace的maxreplace参数只替换第一个出现的

string.replace(s, old, new[, maxreplace])
Return a copy of string s with all occurrences of substring old replaced by new. If the optional argument maxreplace is given, the first maxreplace occurrences are replaced.

string1 = "abcdefga"
string2 = "acd"

for ch in string2:
    string1 = string1.replace(ch, '', 1)

print(string1)
'befga'
