Python language essentials
In this section we will go through the idea of variables, strings, data types, networking, and exception handling. For an experienced programmer, this section will be just a summary of what you already know about Python.
Variables and types
Python is brilliant in case of variables. Variables point to data stored in a memory location. This memory location may contain different values, such as integers, real numbers, Booleans, strings, lists, and dictionaries.
Python interprets and declares variables when you set some value to this variable. For example, if we set a = 1 and b = 2.
Then we print the sum of these two variables with:
The result will be
3 as Python will figure out that both a and b are numbers.
