Variable is used to store different types of data. Python is a dynamically typed programming language, so we don't need to define its type for creating a variable.
Using variables in python.
x = 12
y = 23.34
name= "Jone Doe"
is_local = true
Here we create some variables in different types.
Print Variable:
x = 12
name= "Jone Doe"
print(name)
Rules for Creating Variable:
- Start with a letter or the underscore.
- Can't start with a number.
- Can contain only alpha-numeric characters (A-z, 0-9) and underscores ( _ )
- Variables are case-sensitive (name, Name, and NAME are three different variables)
Some Variable:
varname = "John Doe"
var_name = "John Doe"
_var_name = "John Doe"
varName = "John Doe"
VARNAME = "John Doe"
varname2 = "John Doe"
Camel Case, Pascal Case, and Snake Case:
myVarName = "John Doe" #Camel Case
MyVarName = "John Doe" #Pascal Case
my_var_name = "John Done" #Snake Case
Assign Multiple Values:
Assign multiple values to multiple variables
x, y, z = 10, 20, 30
Same value to multiple variables:
x = y = z = 100
