How to fix 'attributeerror: 'list' object has no attribute...' in python?

Example:

my_list = [1, 2, 3]
print(my_list.add(4))

You're trying to use an attribute/method that doesn't exist for the list data type.

Solution:

Use correct methods associated with the data type.

my_list = [1, 2, 3]
my_list.append(4)
print(my_list)
