Creating strings, indexing, slicing in python

1. Creating Strings

Strings can be created by simply enclosing text within quotes:

2. Indexing

In Python, each character in a string has an index, starting from 0. You can access a specific character by its index.

• Positive indexing starts from the beginning (0, 1, 2, …).
• Negative indexing starts from the end (-1, -2, -3, …).

3. Slicing

Slicing allows you to access a substring or portion of a string by specifying a range of indices.

Tips for Slicing

• start is the beginning index (inclusive).
• stop is the ending index (exclusive).
• step is the interval (or jump) between indices; the default is 1. Negative steps reverse the slice.
