如何在python中将变量转换为数组？

Question

i have a STRING VARIABLE like this:

x = "[str1, str2]"

look, variable x IS NOT an array

when i do:

print x
>>> [str1, str2]

there is a direct way to transform variable "x" from a string variable into an array? Thanks for your answers.

Answer 1

If you really insist, you can do

x = eval("['a', 'b']")

However make sure to read on security issues with using eval

A better solution would be to understand the format of your data and use a parser to get the data you want
