String Operations in Python

In the next set of videos, you will learn about various operations and manipulations done by a string. So, let's have a look at each one of them.

In the previous video, you learned about Indexing in strings. Always remember that forward indexing starts with 0 and reverse indexing starts with -1, strings are immutable which means they cannot be changed once created and strings can be modified by slicing a part of it and concatenating.

Now, let's move on to the next video and understand another important concept string slicing.

In the previous video, you saw slicing in a string through several examples.

In the previous videos, you saw how to do indexing and slicing in strings. But let us say you want to change the character case or count the number of occurrences of a substring in a string, they can be performed using the inbuilt string methods.

In our next video, let's look at these methods in detail.
