Finally, we started our first lesson, the Variables, and String. 

Long story short, variable is used in investment as a symbol of stored values or number. Can we imagine if we do not have liberty in giving up all the name of variables? It will be totally horrible. 

So how to use a variable in the Python? 

First of all typing hello world 

If we want directly print a hello world then it could be

print("Hello world!")

If we want to put hello world in a variable 

variableA = "Hello world!"
print(variableA)

How about concatenation or combination

car_type = "sport"
car_cylinder = 4
car_specs = car_type + "with" + car_cilinder + "cylinder"
print(car_specs)

How to see it in implementation. Check this video.
