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.
