Gain insights into Python 3 by learning basic concepts like keywords and data types, and delving into 50 code puzzles that enhance your understanding of classes and functions.

This course acts as a stepping stone to becoming a Python master. Before getting into advanced concepts like classes and functions, the course begins with Python's basic concepts, such as keywords and data types. Later in this course, you'll be going through 50 code puzzles that will teach you different concepts in Python 3.

An Intro to Python 3

# Advanced functions

Let's look at some advanced functions in Python. 

## Map function

There are two types of map functions:

* `map(func, iter)`:

   It executes the function on all elements of the iterable. 



* `map(func, i1, ..., ik)`:

   It executes the function on all `k` elements of the `k` iterables.

# map(func, iter)
list(map(lambda x: x[0], ['red', 'green', 'blue'])) 
# Result: ['r', 'g', 'b']

# map(func, i1, ..., ik)
list(map(lambda x, y: str(x) + ' ' + y + 's' , [0, 2, 2], ['apple', 'orange', 'banana']))
# Result: ['0 apples', '2 oranges', '2 bananas']

## String functions

* `string.join(iter)`:

  It concatenates iterable elements separated by ​a string​.
