1. The basics

In this section you will start coding right away and learn necessary theory along the way.

Numbers and strings

2. Arithmetic operations

This section will cover arithmetic operation and numeric data types used in Python. Easy material, but you will learn a few nice tricks along the way!

Multiplication and power

Division and whole part division

3. Common data types

In this section you will learn how to store numbers, text etc in computer memory and then will be able to call it by name. Also you will learn little manipulation with text in Python.

Strings slicing

4. Conditional statements

In this section you will learn next data type - boolean and how can it help you to create programs behaving differently dependent on some conditions.

Boolean data type

Combining conditions

Simple if/else expressions (1/2)

Simple if/else expressions (2/2)

If/else expressions with multiple conditions (1/2)

If/else expressions with multiple conditions (2/2)

5. Other data types

In this section you will continue your path in learning different data types in Python: this type you will learn how to store different characteristics inside one variable using lists, tuples and more interesting type dictionaries.

Dictionaries (1/2)

Dictionaries (2/2)

6. Loops

In this section you will learn how to write loops in Python - things ofter used to iterate over some list, tuple, dictionary or even in future dataframe...

while loop (1/2)

while loop (2/2)

7. Functions

In the final section of our introduction course you will learn a bit about built-in functions and then write some functions by yourself!

Built-in functions

Writing your own functions (1/5)

Writing your own functions (2/5)

Writing your own functions (3/5)

Writing your own functions (4/5)

Writing your own functions (5/5)

lambda functions

If/else expressions with multiple conditions (2/2)

Remember the task you completed two chapters ago. There you wrote if/else statement to check whether the number is even or odd. This time let's modify it so now it will detect zeros and negative numbers.

Task

Modify your code (from the exercise about checking if the number is even or odd) so it will detect zero and print the message "This is null" and negative numbers with message "This number is negative". Think carefully about the order of conditions.
