Lets look how to create functions in python.
For example:- We will create two functions:
1. To say “Hello World” to the world.
2. To square a number and get its output.
# Need to use def keyword # then function name # We need to make sure proper indentation is there def hello(name): print("Hello "+ name) # return statement when we want to return a value def square(num): return num*num hello("John") hello("Kitty") result=square(4) print(result)
