How do I check if a string is in Python?
Python is Operator
The most common method used to compare strings is to use the == and the != operators, which compares variables based on their values. However, if you want to compare whether two object instances are the same based on their object IDs, you may instead want to use is and is not .
What is slicing in Python?
Python slice() Function
The slice() function returns a slice object. A slice object is used to specify how to slice a sequence. You can specify where to start the slicing, and where to end. You can also specify the step, which allows you to e.g. slice only every other item.

How do you start writing a for loop in Python?

- It starts with the for keyword, followed by a value name that we assign to the item of the sequence ( country in this case).

- The initializer section ends with “ : ”.
Why address operator is not used in string?
