Python Variable

What is variable in Python ?

Variables are like containers for storing values. A variable in python is a name given to a memory location in a program. Python Variable

# declaring the variable
name = "Fullstackadda.com"

# displaying the output
print(name)
Fullstackadda.com

means name has now assigned to Fullstackadda.com. we can change the value of variables if we want.

Rules to know before you create a variable:

  1. Variables are not written inside double quotes like strings.
  2. A variable name must start with a letter or the underscore character. (A-z, 0-9, and _ ).
  3. A variable cannot have space between it’s letters. (person ✅, per son ❌ )
  4. Some special symbols are allowed.
  5. A variable never starts with a number or a symbol.

Python is as easy as you type english in your texts.

  • The basic type would look like
a=10 
b=20 
c=a+b 
print(c)

if you are taking input from the user then the code would be like:

a=input() 
b=input() 
c=a+b 
print(c)

If you want to save some steps there and don’t want to take another variable to store the result, then code will be like

a=int(input("enter"))     
b=int(input()) 
print(a+b)

Different Examples:

Assigning multiple variables:

a, b, c = 1, 2, 3

print(a)
print(b)
print(c)

1
2
3

Using + operator :

a = 5
b = 5
print(a+b)

a = "Fullstack"
b = "adda"
print(a+b)
10
Fullstackadda
a = 1
b = "two"
print(a+b)

Output:
