Variable, Constant, and Literals Declaration in Python:-
Variable:-
it is an identifier that is used to contain values in the program. variable value and type can be changed in the program at run time.
Python variable datatype will be managed by the assigned value. Python variable type and memory allocation depend on assigned data .we can provide multiple data types for a single variable in the python program.
Python variable is a loosely coupled type declaration so that we can change variable datatype in the program.
The syntax for Variable Declaration in Python:-
identifier=value #single value
identifier1,identifier2,...= value1,value2,.. #multiple variable, multiple value
a=10
a,b,c = 10,20,30
a,b=10,20
print(a+b)
Example of variable:-
a,b = input("enter first number"),input("enter second number")
print(a+b) # "10"+"20" "1020"
print(int(a)+int(b)) # 10+20
print(int(a+b)) # 1020 int
print(int(a)+float(b))
the naming convention of variable:-
variable name always will be started by alphabets, without using space, keyword.
the variable identifier will be declared in the lower case according to the python naming convention.
Constant:-
it is a special identifier in the Python program whose values can not be changed dynamically.
Python provides a list of the constant that is called a tuple.
tuple variable value can not be modified in the program and outside from the program
identifier = (value1,value2,value3,..)
const = (3.14,2.2,"http://www.shivaconceptsolution.com")
Literals:- It is the value of variable and constant for example if we assign
a=2 # 2 is the integer type literals
b = 3.14 # 3.14 is the float type literals
print("hello") # hello is the string type literals
a=2 # 2 is the integer type literals
b = 3.14 # 3.14 is the float type literals
print("hello") # hello is the string type literals
Example of Literals:-
print(10+20) #10,20 is the integer type literals
print("hello"+"how r u") # hello, how r u is the string type literals
