What is lambda in Python? Why is it used?

Lambda function in Python can accept any number of arguments, but can only have a single expression. It is generally used in situations requiring an anonymous function for a short time period. Lambda functions can be used in either of the two ways:

• Assigning lambda functions to a variable

division = lambda x, y : x / y
print(division(12, 3))    # output => 4.0

• Wrapping lambda functions inside another function

def wrapperfun(n):
  return lambda x : x * n

mulvalue = wrapperfun(8)
print(mulvalue(3))    # output => 24
