Indexing means fetching the specific character object
Slicing means access the range of characters
Different types of sequences in python are strings, Unicode strings, lists, tuples, buffers, and xrange objects
Slicing & indexing operations are salient features of sequence.
indexing operation allows to access a particular item in the sequence directly ( similar to the array/list indexing) and the slicing operation allows to retrieve a part of the sequence.
The slicing operation is used by specifying the name of the sequence followed by an optional pair of numbers separated by a colon within square brackets say S[startno.:stopno].
The startno in the slicing operation indicates the position from where the slice starts and the stopno indicates where the slice will stop at.
If the startno is ommited, Python will start at the beginning of the sequence. If the stopno is ommited, Python will stop at the end of the sequence..
Following code will further explain indexing & slicing operation:
>>> cosmeticList =[‘lipsstick’,’facepowder’,eyeliner’,’blusher’,kajal’]
>>> print “Slicing operation :â€,cosmeticList[2:]
Slicing operation :[‘eyeliner’,’blusher’,kajal’]
>>>print “Indexing operation :â€,cosmeticList[0]
“Indexing operation :lipsstick

Right Answer:
To test a Python program or component, you can use the built-in `unittest` framework or third-party libraries like `pytest`. Write test cases in a separate file, define test functions or classes, and use assertions to check expected outcomes. Run the tests using the command line or an integrated development environment (IDE) that supports testing.
