Introduction to blog series

This blog post will be part of a series of blog posts which I will be publishing regarding what I have been reviewing and learning in Python.

Variables in Python

Variables in Python can be declared either with a data type or without one. For example, if we want to declare a variable of type string, we would do the following:

message = str("Hello World")

We can also declare it without any declaration or type hinting of the data type and leave it up to the interpreter to figure it out as follows:

message = "Hello World"

Checking data type of variable

In the latter case if we want to find out the data type, we would do the following:

NOTE: # is used to comment in Python

type(message) #<class, 'str'>


isinstance(message, str) #True
