can't multiply sequence by non-int of type 'builtin_function_or_method'

This error occurs when you try to multiply a sequence (e.g., a list or a string) with a non-integer value, which is typically a built-in function or method. To resolve this issue, you need to make sure that you are using an integer value for multiplication.

For example, instead of:

sequence = [1, 2, 3]
multiplier = len
result = sequence * multiplier

You should use:

sequence = [1, 2, 3]
multiplier = 3
result = sequence * multiplier

In this case, the sequence will be multiplied by an integer value of 3, resulting in `[1, 2, 3, 1, 2, 3, 1, 2, 3]`.
