Variables in Python Programming, In this tutorial, we will learn how to assign variables in Python to your code and why it is important. Here, You will also learn python variable rules which are helpful for any Python developers. Are you looking for the Python variables tutorial with examples or Are you dreaming to become to certified Pro Python Developer, then stop just dreaming, get your Python certification course from India’s Leading Python training institute.
A variable in Python is a memory address which we can change, and the variable is known as constant when the memory address cannot change. Variable is the name of the memory location where data is stored. Once a variable is stored, space is allocated in memory. It defines a variable using a combination of numbers, letters, and the underscore character. As we know Python has dynamically typed language when declaring one variable we don't specify the type of variable.
Do you want to know Variables in Python programming and how to assign variables in Python, then just follow the below mentioned Python variables tutorial for Beginners from Prwatech and take advanced Python training like a Pro from today itself under 10+ years of hands-on experienced Professionals.
What are Python Variables?
Variables are containers to store a data value. Unlike other programming languages, Python doesn’t have any command for declaring a variable. Variables need not be declared with any particular kind and can even change type after they have been set. String variables are declared either by using single or double quotes:
Python Variables Example
x= 10
z = “PrwaTech”
y= ‘Python’
Python variables Rules
A variable name should start with a letter or the underscore character. A variable name should not start with a number. variable name can only have alpha-numeric characters and underscores (A-z, 0-9, and )
Variable names are case-sensitive in nature (python, Python, and PYTHON are three different variables)
Multiple Variable Assignment in Python
Python allows you to assign values to multiple variables in a single line:
Example:
x, y, z = "One", "Two", "Three"
And you can assign the same value to multiple variables in a single line:
Example:
x, y, z = "One"
Output Variables
In Python print statement is often displaying the output variables. To combine a text with a variable, Python uses the + character. You can use the + character also to add a variable to another variable. For numbers, + character works as a mathematical operator
If you try to combine a string with a number, Python will throw you an error.
Output Variable Example
x= 4
print(x)
y= “Python”
print(y)
z= “Python”
print (“hello”, +z)
k= “Hello”
l= k+z
print(l)
a=3
b=4
print(a+b)
