The lambda function is an anonymous function. It can have any number of arguments but it can only have one expression.
Syntax lambda arguments : expression
In this article, we will learn how to find the smaller value between two elements using the Lambda function.
Example:
Input : 2 5 Output : 2 Input : 7 5 Output : 5
Method 1: Using lambda and min() method
Python3
# lambda function to return minimum of # two elements a, b are the arguments and # min() method is the expression here. get_min = lambda a, b : min(a,b) print(get_min(5, 8)) |
Output:
5
Explanation: The a,b are passed to the lambda function and min() method is used as an expression to return the minimum element.
Method 2: Using lambda and ternary operator
Python3
# lambda function to return minimum of two elements # a, b are the arguments and ternary # operator is used to compare two elements get_min = lambda a, b : a if a < b else b print(get_min(5, 8)) |
Output:
5
Explanation: a, b are the arguments and ternary operator is used for comparing two elements
Method 3 :Using Tuple and lambda
Python3
# Two lambda functions will be stored # in tuple such that 1st element is b # and 2nd element will be b. # if [a<b] is true it return 1 and # element with index 1 will print # else if [a<b] is false it return 0, # so element with index 0 will print a = 5b = 8print((lambda: b, lambda: a)[a < b]()) |
Output:
5
Explanation:
Two lambda functions will be stored in a tuple such that 1st element is b and 2nd element will be b. if [a<b] is true it return 1 and element with index 1 will print else if [a<b] is false it return 0, so element with index 0 will print.
