python what is lambda code example

Example 1: lambda python

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

Example 2: 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 3: 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))

Example 4: lambda function 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: lambda function in python

>>> def identity(x):
...     return x

These two functions do the same thing

>>> lambda x: x
