Function :
A function is a block of code which only runs when it is called. You can pass data, known as parameters, into a function.
There are two types of function in python.
Built-in library function (pre-defined function)
User-defined function
*Built-in library function: *
There are Standard functions in Python that are available to use.
for Example :
input()
print()
input() function :
The input() function allows user input.
for example :
x = input("Enter your name : ")
print() function
The print() function prints the specified message to the screen, or other standard output device.
for example
print("welcome to our class")
User-defined function:
We can create our own functions based on our requirements.
We can define a function in Python, using the def keyword. We can add any type of functionalities and properties to it as we require.
for example
A = int(input("Enter your A value"))
B = int(input("Enter your B value"))
C = input("Enter your operator")
def calculate(A,B,C):
if C == '+':
print("Addition--->",A,B)
if C == '-':
print("Substractionn---->",A-B)
calculate(A,B,C)
*Result *
Enter your A value10
Enter your B value20
Enter your operator+

Enter your A value20
Enter your B value10
