python - 如何将一串电子邮件地址排序到列表中

Question

我想将包含电子邮件地址的字符串排序为电子邮件地址列表。代码卡住了，没有任何反应。

unsorted = "sge@grg.lt ggrge@yahoo.com"
def sort_thatstring():
    s = ""
    out = []
    for x in unsorted:
        s = ""
        while x != " ":
            s+=str(x)
        else:
            out.append(s)
sort_thatstring()
print out

我想得到:

out = ["sge@grg.lt", "ggrge@yahoo.com"]

Answer 1

你可以这样做:

sorted_list = sorted(unsorted.split(), key=lambda x: x.split('@')[1])

print(sorted_list)
#['sge@grg.lt', 'ggrge@yahoo.com']
