可以使用^{}安全地对字符串求值：

Safely evaluate an expression node or a string containing a Python literal or container display. The string or node provided may only consist of the following Python literal structures: strings, bytes, numbers, tuples, lists, dicts, sets, booleans, and None.

In [1]: from ast import literal_eval

In [2]: literal_eval("[1,2,3,4,5]")
Out[2]: [1, 2, 3, 4, 5]
