如何拆分字符串中的数字？

Question

例如 :

je = ("3,5&6,7")

而我想要的结果是[3,5,6,7]

到目前为止我尝试了什么:

je = ("3,5&6,7")
jean = je.split(",")
j = str(jean)
De = j.split("&")
print De

但我的结果是["['3','5","6','7']"]

用途regex:

In [3]: import re

In [4]: strs = "3,5&6,7"
#map
In [5]: map(int, re.findall(r'\d+',strs))
Out[5]: [3, 5, 6, 7]
#LC
In [6]: [int(x) for x in  re.findall(r'\d+',strs)]
Out[6]: [3, 5, 6, 7]
