Remember data types we learned previously? `for` loop can easily iterate over some of them. For example, you can easily iterate over a string to get all symbols from it.

# iterate over string
s = "small string"
for i in s:
  print(i)

# iterate over list
l = [1, [2,3], 4, "wow"]
for i in l:
  print(i)

This course on Python requires zero prior knowledge on programming. It uses simple examples and covers same key concepts with greater level of detail in each subsequent section. Enough said, click start and beging coding!

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

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!

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.

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. 

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.

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...

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