In the previous examples (for example in the Conditional Statements Section), we assigned different values to a variable just to check if our code was working as needed. This might be uncomfortable, especially when our code becomes larger and larger. This can be solved by using functions. To define a function, use syntax:

def name_of_function(var1, var2...):
  body of function
  return smth

For example, let's define a simple function that receives two numbers and returns their sum squared.

# Define function
def sum_squared(a, b):
  return (a+b)**2

# Call function
print(sum_squared(2,3))

In this section, you will be introduced to the very basics of Python and to your workspace, learn some simple math operations, and print your results.

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

In this section, you will learn the next data type - boolean - and how it can help in creating programs that behave differently depending on certain conditions. 

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

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

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