[英]Convert string of list into list of int
how do I convert a string of integer list into a list of integers? 如何将整数列表的字符串转换为整数列表?
Example input: (type: string) 输入示例:(类型:字符串)
"[156, 100, 713]"
Example conversion: (type: list of int) 转换示例:(类型:int列表)
[156, 100, 713]
Try this: 尝试这个:
import ast
res = ast.literal_eval('[156, 100, 713]')
Read more about ast.literal_eval in python docs. 在python文档中阅读有关ast.literal_eval的更多信息。
use ast.literal_eval
on it and you're done. 在上面使用
ast.literal_eval
完成。 Here you don't have all the security issues of regular eval
and you don't need to worry about making sure your string is well formed, etc. Of course, if you really want to parse this thing yourself, you can do it with a pretty simple list-comprehension: 在这里,您没有常规
eval
所有安全性问题,也不必担心确保字符串格式正确等。当然,如果您真的想自己解析此事情,则可以使用一个非常简单的列表理解:
s = "[156, 100, 713]"
print [ int(x) for x in s.translate(None,'[]').split(',') ]
>>> import json
>>> a = "[156, 100, 713]"
>>> json.loads(a)
[156, 100, 713]
