anonymous function python code example

Example 1: python anonymous function

def sum ( a, b ):			# non anonymous
        return a+b
print (sum(1, 2))			# 3

sum = lambda a,b: (a+b)		# anonymous / lambda
print (sum(1, 2))			# 3

Example 2: python anonymous function

# You have to save the lambda expresion for it to work

nameOfLambda = lambda arg1, arg2: expression

Example 3: lambda python

add = lambda a, b : a + b
add(3,6) ## 9

Example 4: what is lambda in python

Lamda is just one line anonymous function
Useful when writing function inside function
it can take multiple arguments but computes only one expression

Syntax:
   x = lambda arguments : expression

Example 5: python lambda

multiply = lambda x,y: x * y
multiply(21, 2) #42
#_____________
def myfunc(n):
  return lambda a : a * n

mydoubler = myfunc(2)
print(mydoubler(11)) #22

Example 6: lambda function in python

In Python, an anonymous function is a function that is defined without a name.

While normal functions are defined using the def keyword in Python, 
anonymous functions are defined using the lambda keyword.

Hence, anonymous functions are also called lambda functions.

# syntax of Lambda function
lambda arguments: expression

# Program to show the use of lambda functions
double = lambda x: x * 2

print(double(5))
