25.1.1. Parameters/Arguments
(a) An argument is an expression which is passed to a function by its caller, in order for the function to perform its task.
(b) Parameters are local to the particular function.
(c) Parameters are available only with in the specified function
25.1.2. Writing a simple function with arguments
d = int(input("a: "))
e = int(input("b: "))
def add(a,b):
#perform addition on the passed parameters
x = a+b
#return the result
return(x)
x =add(d,e) #call the add() by passing d and e arguments
print(x)
25.1.3. A simple function with a single argument
def sayhello(n):
x = "Hello"
print(x, n)
#write your code here..
name= input("")
sayhello(name)
25.1.4. Write a program to print a pascal triangle using functions
def pascal(n):
for i in range(1,n+1):
c=1
list1=[]
for j in range(1,i+1):
list1.append(c)
c=c*(i-j)//j
print(list1)
#write your code here..
i = int(input("num: "))
pascal(i)
25.2.1. Keyword arguments - an overview
(a) When values are provided as arguments to a function using their respective parameter names, allowing assignment in any order, these arguments are called as keyword arguments.
(b) Calling the function add(a = 10, b = 20) or by add(10, 20), produce the same result.
25.2.2. Writing an example using keyword arguments
def simplecalc(a, b):
print(a+b)
print(a-b)
print(a*b)
#fill in the missing code..
a = int(input())
b = int(input())
simplecalc(a,b)
simplecalc(a=b,b=a)
25.2.3. Writing an example for keyword arguments
def saysomething(name, message):
print("Good", message, name)
#write ypur code here..
n= input("name: ")
m= input("morning/night: ")
saysomething(n,m )
saysomething(message=m,name=n)
25.2.4. Illustration of Keyword arguments
def nameage(*, name, age):
print(name, age)
#fill in the miising code..
name = input("name: ")
age = int(input("age: "))
nameage( age= age, name= name )
nameage( name=name, age=age )
