Suppose we have a string. Now it's time to learn how we can work with it. First, let's learn how to access certain string characters.

Use square brackets with an index inside to access a particular string element. An index is not a position of a specific element since indexing in Python starts from 0. Take a look at the example below.

As you can see, the index in Python is always 1 less than the position. For example, we can get several letters of the word above.

# Initial string
site = "codefinity"
# Get the letters 'o' and 'y'
print(site[1], site[9])

Suppose you are given the string test (in the code below). Choose the element that has index 5.

Python is an interpreted high-level, general-purpose programming language, which means it can be used in different spheres of human activity (unlike HTML, CSS, and JavaScript, which are mainly used in web development). Python can be used in software developing, data science, back-end development, etc. In this mobile-friendly version of the course, you will meet with the main aspects of Python.

In the first section, you will be introduced to the very basics of Python - how to interact with Python, perform simple operations, and output results.

In the past section, you performed different operations with numbers. In this section, you will learn how to save values in computer memory and be able to use them in the future for any purpose.

During the last two sections, you mostly worked with numerical data. In the third section, you will learn how to work with textual data in Python (strings), how to manipulate such data, what methods can be applied to them, and so on.
