# # Introduction to Python Statements
# 
# In this lecture we will be doing a quick overview of Python Statements. This lecture will emphasize differences between Python and other languages such as C++. 
# 
# There are two reasons we take this approach for learning the context of Python Statements:
# 
#     1.) If you are coming from a different language this will rapidly accelerate your understanding of Python.
#     2.) Learning about statements will allow you to be able to read other languages more easily in the future.

# ## Python vs Other Languages
# 
# Let's create a simple statement that says:
# "If a is greater than b, assign 2 to a and 4 to b"
# 
# Take a look at these two if statements (we will learn about building out if statements soon).
# 
# **Version 1 (Other Languages)**
# 
#     if (a>b){
#         a = 2;
#         b = 4;
#     }
#                         
# **Version 2 (Python)**   
# 
#     if a>b:
#         a = 2
#         b = 4

# You'll notice that Python is less cluttered and much more readable than the first version. How does Python manage this?
# 
# Let's walk through the main differences:
# 
# Python gets rid of () and {} by incorporating two main factors: a *colon* and *whitespace*. The statement is ended with a colon, and whitespace is used (indentation) to describe what takes place in case of the statement.
# 
# Another major difference is the lack of semicolons in Python. Semicolons are used to denote statement endings in many other languages, but in Python, the end of a line is the same as the end of a statement.
# 
# Lastly, to end this brief overview of differences, let's take a closer look at indentation syntax in Python vs other languages:
# 
# ## Indentation
# 
# Here is some pseudo-code to indicate the use of whitespace and indentation in Python:
# 
# **Other Languages**
# 
#     if (x)
#         if(y)
#             code-statement;
#     else
#         another-code-statement;
#         
# **Python**
#     
#     if x:
#         if y:
#             code-statement
#     else:
#         another-code-statement

# Note how Python is so heavily driven by code indentation and whitespace. This means that code readability is a core part of the design of the Python language.
# 
# Now let's start diving deeper by coding these sort of statements in Python!

# ## Time to code!
