1. Getting Familiar With Numbers in Python

Numeric data types are crucial in Python, so it is important to start with them. Here you will work with simple math operations and find out the purposes of learning different types of numerical data.

Numerical Data Type in General

Mutable or Immutable?

Integer Numbers

Compulsory Math

Complicated Math

Time Calculation

How to Define a Type

2. True or False?

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.

Introduction to Boolean Data Type

Logical Statements

And, Or, Not Operators

Boost Your Logical Skills

Dealing With Not Statement

Work With Logical Statements

3. Strings

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.

Print Your String

Quotation Marks

Get Acquainted With Indexation

Negative Indexation

Slice the Phrase

How to Find the String Length

Get the Index of the Symbol

Find the Word Index

Slicing with Index Function

Is String Mutable?

4. Bring All the Topics Together

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

Useful Converting

Converting: float()

Converting: bool()

Converting: str()

Math in Strings

Compare Strings

Get the Index of the Symbol

Wow! We've done a lot!

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:

Task

Hone your skills as much as possible!

So here you should find the index of the letters p,y, and r.

Everything was clear?
