The purpose of def keyword in python is to indicate start the function and it also indicates that the piece of code following the def keyword is to stored so that it can later be used in the program.
For ex:
def check(n):
if n==10:
return True
return False
n=int(input("Enter an integer\n"))
if check(n):
print("n is 10")
else:
print("n is not 10")
In the above written code the function check is defined by using the keyword def.It also tells the interpreter to store the code because we will need it in future.
