Question

我有一个二维数组 [['s1.modernroleplay.net', '27016', '27015'], ['s2.modernroleplay.net', '27019', '27018'], ['s3.modernroleplay.net', '27022', '27021']]

此2d数组存储在MySQL中，一旦将其从MySQL中取出，它就是字符串格式。

如何将这个字符串转换回数组？

Answer 1

您可以尝试：

import json

my_string = "[['s1.modernroleplay.net', '27016', '27015'], ['s2.modernroleplay.net', '27019', '27018'], ['s3.modernroleplay.net', '27022', '27021']]".replace("'", '"')

my_array = json.loads(f'{{"array" : {my_string}}}')['array']
print(my_array)

# output
# [['s1.modernroleplay.net', '27016', '27015'],
#  ['s2.modernroleplay.net', '27019', '27018'],
#  ['s3.modernroleplay.net', '27022', '27021']]

Answer 2

您可以使用ast

例如：

import ast

print(ast.literal_eval("[['s1.modernroleplay.net', '27016', '27015'], ['s2.modernroleplay.net', '27019', '27018'], ['s3.modernroleplay.net', '27022', '27021']]"))
