It is time to share some insights. In fact, there is no necessity to **manually specify the index** of the symbol to find it in the string; it seems we have an intuition for this, as we recognize Python's user-friendly approach and attentiveness to its users.

Hence, the `find()` function was implemented.

> Note

> It will be beneficial to understand that this method is useful when we seek to determine the index of a particular symbol or word within a text. Additionally, it is important to note that this method returns the index of the first occurrence of the substring. In cases where the **substring is not found**, it returns a value of '-1'.

Take a look at the example; it will help you get the syntax:

string = "Channel efforts to success!"
print(string.find('n'))

This course is going to help you dive deeper into data types and try to work with them. Here you will learn basic operations and all ins and outs of numbers, boolean data type, and strings. This course consists of a lot of practical tasks after which you will become a skillful programmer.

Numerical data types are fundamental in Python, forming the backbone of many computational tasks. In this section, you'll dive into the essentials of working with integers and floating-point numbers, performing basic mathematical operations, and understanding the real-world applications of numerical data. You'll also explore critical concepts such as immutability and gain hands-on experience with Python’s built-in functions and tools for handling numbers effectively.

The main goal of this section is to clarify the boolean data types; it's a sub type of numeric data, but indeed it is more challenging. Since it is always better to excel in the more difficult topics, this section is a valuable part of your curriculum.

Strings are a way for us to implement your phrases in Python, that is, to give instructions to users who are the target audience of your program. Indeed, it is always better to be able to work with strings because they should be used in your code. You'll understand why soon.

This chapter consists of practical tasks that combine all the examined topics together with a bit of theory.
