Python issue, Index out of bound #1

Open AshutoshRaval opened 10 months ago

fruits = ["apple", "banana", "orange", "pear", "grapes", "watermelon"] print(fruits[6]) Traceback (most recent call last): File "", line 2, in IndexError: list index out of range

The issue here is that Python list indices begin at 0, so a list of six elements has indices ranging from 0 to 5. Attempting to access fruits[6] throws an IndexError because there is no seventh element in the list.

The correct code should limit access to the indices to the specified list range. For instance:

fruits = ["apple", "banana", "orange", "pear", "grapes", "watermelon"]
print(fruits[5])  # This will print "watermelon"

You can always check the length of your list using len() function and ensure you're not trying to access an index that falls outside this range:

print(len(fruits))  # This will print 6, meaning that the indices go from 0 to 5

To avoid such errors in the future, you can also use a try and except block that catches the IndexError and prints an appropriate message:

try:
    print(fruits[6])
except IndexError:
    print("That index is not in the list.")

These changes should resolve your issue.

You are correct that you are experiencing an IndexError due to trying to access an index that is out-of-bounds of your list. Python list indices start from 0, so a list of six items (like fruits) would have valid indices from 0 to 5. Attempting to access fruits[6] is out-of-bounds and thus, throws an exception.

Here is an example of how you should correct this:

fruits = ["apple", "banana", "orange", "pear", "grapes", "watermelon"]
print(fruits[5])  # last item, "watermelon" is at index 5, not 6

You can also add checks in your code to prevent such errors:

index = 6
if index < len(fruits):
    print(fruits[index])
else:
    print("Index is out of bounds!")

This way, you escape the IndexError by ensuring that the index is within the bounds of the list before trying to access the item at that index. If the index is out of bounds, a warning message will be printed instead. Please adapt this to your needs.
