Theindex()method is used to find the index of the first occurrence of a specified element in a list. This method is particularly useful when you need to know the position of a specific element within a list. Here’s an example of how to use theindex()method to find the index of the...
2. What is the difference between slicing and indexing? 3. How does python handle argument passing: by reference or by value? 4. What is the significance of self in Python classes? 5. How do you find the middle element of a linked list in one pass? 6. What are collections? What is...
