Intro To Python 3: Variables
Basics of Python...
Python 3 :-
To start programming in python3 we need to know some python Language Basics, such as; variables,
what they are and how to use them; also some basic functions that are included by default in
python3 like print, # or + and - in our example
definition by the book:
variables = is a reserved memory location to store values. in other words, restores data
to a place in computers memory.
our Definition:
variable = is a bag that stores data. data can be a number or a string (word).
For today's Example, We will be using some variables to show how they can be used...
also some basic math functions and how to print them out.
I will be using https://trinket.io/ to write and use the Python code..
#Example 1: we will make a small program that will display the sum of 2 numbers...
we use hashtags to write a comment and python will ignore anything after the hashtags row
#Example 1:
to calculate 2 numbers we need to assigin every number to a variable (or a bag).
num1 = 5 # we named our first bag as num1, a shurt cut for first number
#and gave it a value of 5 by the symbole of equal or =
num2 = 6 # we named our 2nd bag as num2 with the value of 6.
TotalOfNums= num1 + num2 # to get the sum of the values in num1 and num2 we have to tell
#Python to take num1's value which is 5 and add it to the value of num2 and set the sum to
#the bag that we named TotalOfNumbers.
#to print (show or disply) the value of TotalOfNumbers we use the print function like this..
print(ToatalOfNumbers)
#Now lets go to run the code...
++++++++++++++++++++++++++++++++++++
num1 = 5
num2 = 6
TotalOfNumbers = num1 + num2
print(TotalOfNumbers)
+++++++++++++++++++++++++++++++
Thanks for watching :)
