5 Python lambda Function with Examples
Python lambda is a anonymous function. Its created with lambda keyword. We can assign many arguments with one expression.
Syntax:
Lambda Expression: arguments
Use of Lambda function:
It is used to create a function within the function for short period of time.
In this tutorial, you will learn about Python lambda Function with Examples
Example Program 1: calculate power
power = lambda x: x ** 2
print(power(5))
Output: 25
Example Program 2: To print even numbers
my_list = [1,2,3,4,5,7,8,9,10]
even = list(filter(lambda x: (x%2 == 0) , my_list))
odd = list(filter(lambda x: (x%2 != 0) , my_list))
print('Even Numbers',even)
print('Odd Numbers',odd)
Output:
Even Numbers [2, 4, 8, 10]
Odd Numbers [1, 3, 5, 7, 9]
Example Program 3 : lambda program with map function
my_list = [1,2,3,4,5,7,8,9,10]
even = list(map(lambda x: (x%2 == 0) , my_list))
odd = list(map(lambda x: (x%2 != 0) , my_list))
# Output: [4, 6, 8, 12]
print('Even Numbers',even)
print('Odd Numbers',odd)
Output:
Even Numbers [False, True, False, True, False, False, True, False, True]
Odd Numbers [True, False, True, False, True, True, False, True, False]
Example Program 4: Find biggest number
bigger_number = lambda x,y: x if (x>y) else y
print(bigger_number(5,2))
Output:
5
Example Program 5: Find smallest number
small_number = lambda
x,y: x if (x Output:
2
