python - 在一些字符后替换字符串

Question

如何替换字符串中的子字符串？例如我有字符串:

string1/aaa
this is string2/bbb
string 3/ccc
this is some string/ddd

我想读取“/”之后的子字符串。我需要这个输出:

aaa
bbb
ccc
ddd

谢谢。

Answer 1

可以拆分字符串获取数据

my_string.split("/")[1]

例如，

data = ["string1/aaa", "this is string2/bbb", "string 3/ccc",
        "this is some string/ddd"]    
print [item.split("/")[1] for item in data]

输出

['aaa', 'bbb', 'ccc', 'ddd']
