3 Powerful Functions In Python

Lambda Function

Lambda function does not have any name like user-defined functions. It takes n number of arguments but it can have only one expression.

Example:

x = lambda a : a + 10

print(x(5))

Output:

10

Map Function:

Map function iterates on iterable elements without using loops and executes the specified function for each element.

Example:

def add(n):

return n + n

numbers = (1,2,3)

result = map(add, numbers)

print(list(result))

Output:

[2, 4, 6]

Zip Function:

It is used to return zip object which contains the iterator of tuples having the same indexed items of each passed iterable is paired together.

Example:

a = ("Ali", "Zahid", "Zain")

b = ("Ali", "Sohail", "Sajid")

x = zip(a,b)

print(list(x))

Output:

[('Ali', 'Ali'), ('Zahid', 'Sohail'), ('Zain', 'Sajid')]
