'zip' object has no attribute 'insert'

This error occurs when you try to use the `insert()` method on a `zip` object. The `zip()` function returns a zip object which is an iterator of tuples. Zip object doesn't have an `insert()` method, so you cannot use it on a `zip` object.

For example:

a = [1, 2, 3]
b = ['a', 'b', 'c']
z = zip(a, b)
z.insert(0, (4, 'd'))

This will give the error:

AttributeError: 'zip' object has no attribute 'insert'

To fix this error, you can convert the `zip` object to a list and then use the `insert()` method on it.

a = [1, 2, 3]
b = ['a', 'b', 'c']
z = list(zip(a, b))
z.insert(0, (4, 'd'))

This will work without any errors.
