Lambda Expression-

  • 1) It is a keyword used to define a function as an expression.
  • 2) All the functions can not be written as lambda expression.
  • 4) If any function is having only 1 line logic statement then only that function can be written as Lambda expression.
  • 5) We can also return the value from Lambda expression.

Ex-(Normal Function)-

def test(name):
    print("Hi-",name)
name = input("Enter your name-")
test(name)

Output-
	Enter your name-Python
	Hi- Python

Converted Above Function In Lambda Expression-

name = input("Enter your name-")
test = lambda name: print("Hi-", name)
test(name)

Output-
	Enter your name-Python
	Hi- Python

Ex-(Normal Function)-

def even_chk(no):
    if no%2 == 0:
        return True
    else:
        return False

no = int(input("Enter the no-"))
if even_chk(no):
    print("This is an even no.")
else:
    print("This is not an even no.")

Output-
	Enter the no-9
	This is not an even no.

Converted Above Function In Lambda Expression-

even_chk = lambda n:n%2==0
no = int(input("Enter the No-"))
if even_chk(no):
    print("This is an even no.")
else:
    print("This is not an even no.")

Output-
	Enter the No-8
	This is an even no.

Ex-

biggest = lambda a,b,c: a if a>b and a>c else b if b>c else c
x = int(input("Enter 1st no-"))
y = int(input("Enter 2nd no-"))
z = int(input("Enter 3rd no-"))
print("Biggest no is-", biggest(x, y, z))

Output-
	Enter 1st no-7
	Enter 2nd no-4
	Enter 3rd no-3
	Biggest no is- 7
