Python-如何将字符串转换为数组

Question

I have a 2d array [['s1.modernroleplay.net', '27016', '27015'], ['s2.modernroleplay.net', '27019', '27018'], ['s3.modernroleplay.net', '27022', '27021']]

This 2d Array is stored in MySQL, once taking it out of MySQL it is in a String format.

How can I convert this string, back into an array?

Answer 1

you can try:

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

You can use ast

for example:

import ast

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