TypeError: list indices must be integers or slices, not float

This error occurs when you try to use a float value as an index for a list.

For example:

my_list = [1, 2, 3, 4, 5]
print(my_list[2.5])  # This will raise a TypeError

To fix this error, make sure you are using integer values as list indices. If you need to use a float value, you can convert it to an integer using the `int()` function:

my_list = [1, 2, 3, 4, 5]
print(my_list[int(2.5)])  # This will print 3
