Fix TypeError: list indices must be integers or slices, not str

This error occurs when you try to access a list element using a string as the index, while list indices in Python must be integers or slices. To fix this error, you need to ensure that you use an integer or a slice as the index when accessing elements in a list.

Here’s an example of code that might cause the error:

Python

my_list = ["apple", "banana", "cherry"]
index = "1"
fruit = my_list[index]  # This will raise a TypeError

To fix the error, convert the string index to an integer using the int() function:

Python

my_list = ["apple", "banana", "cherry"]
index = "1"
fruit = my_list[int(index)]  # This will work correctly

If the index is already an integer, make sure you’re not accidentally using a string instead of an integer variable:

Python

my_list = ["apple", "banana", "cherry"]
index = 1
fruit = my_list[index]  # This will work correctly

By ensuring that you’re using integer or slice indices when accessing list elements, you can fix the TypeError: list indices must be integers or slices, not str error.
