This error occurs when you try to access an index in a tuple that does not exist.
For example, if you have a tuple with three elements and you try to access the fourth element using an index of 3, you will get this error.
Here's an example code snippet that could cause this error:
```
my_tuple = (1, 2, 3)
print(my_tuple[3])
```
In this case, the index 3 is out of range because the tuple only has three elements. To fix this error, you need to make sure that the index you are trying to access is within the range of the tuple.
Here's an updated version of the code that avoids the error:
```
my_tuple = (1, 2, 3)
print(my_tuple[2])
```
In this case, we are accessing the third element of the tuple using an index of 2, which is within the range of the tuple.
