this is tuple, which my microcontroller is able to recognize and

It works with a fixed string input but using eval() is a big security risk,
especially if you read the input from a file or network or even a user.
You could potentially find your hard disk being formatted or similar damage.
An explicit conversion using int() is much safer.
