A1: If the element is not found, the index() function raises a ValueError exception. To handle this scenario, you can use error handling techniques like a try-except block or check if the element exists in the list using the in operator. Q2: Can I use the index() function with other ...
An index in Python refers to aposition within an ordered list. To retrieve an element of the list, you use theindex operator ([]). Using indexing you can easily get any element by its position. Python strings can be thought of aslists of characters; each character is given an index fro...

The multiplication operator (*) converts these values to 0s and 1s and then performs the multiplication operation which converts all other values to 0s except the desired output. MATCH(1,(0;0;0;0;0;0;0;0;0;0;0;0;1;0;0;0;0;0;0;0;0),0)): The MATCH functionlooks for the ...

In the above approach, you will get the leftmost index of the minimum element if there are multiple occurrences of the element in the list. To obtain the rightmost index at which the minimum element is present, you can use the less than or equal to operator instead of less than operator ...
In this example, we have passed index 23 to the indexing operator. As 23 is greater than the length of the tuple, the program runs into thePython IndexErrorexception. To solve this problem, you can first check if the value passed to the indexing operator is greater than or equal to the...
