IndexError: list index out of range

This error occurs when you try to access an index of a list that does not exist. For example, if you have a list with three elements and you try to access the fourth element (which does not exist), you will get this error.
Here is an example code that can cause this error:
```
my_list = [1, 2, 3]
print(my_list[3]) # This will raise an IndexError
```
To fix this error, you need to make sure that you are accessing a valid index in the list. You can check the length of the list using the `len()` function and make sure that the index you are trying to access is within the range of valid indices.
Here is an example code that avoids the IndexError by checking the length of the list:
```
my_list = [1, 2, 3]
if len(my_list) >= 4:
print(my_list[3])
else:
print("Index out of range")
```
