Condition for Anonymous Function or Lambda Function in Python
Description: A lambda function in Python is a concise, anonymous function defined with the lambda keyword.Unlike regular functions, lambda functions do not require a name and can be used inline for small,simple operations.
Step-by-Step Process
Lambda can have multiple arguments but only one expression.
The expression is evaluated and returned automatically when the lambda function is called.
Lambda functions are commonly used in functions like map(), filter(), and reduce() to process data in a more compact form.
Sample Code
# Lambda function
print("Output for using lambda function")
max_number = lambda a, b: a if a > b else b
result = max_number(10, 20)
print(result)
print()
# Using lambda with filter to get even numbers
print("Output for lambda function using filter keyword")
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
even_numbers = filter(lambda x: x % 2 == 0, numbers)
print(list(even_numbers))
