A tuple consists of a number of values separated by commas,

Lambda Expressions

To learn Lambda Expression, first we will look into built in functions, Map and Filter.

Map Function

Map function maps your function to an iterable object. Let’s see an quick example where we are calculating the square of each element of an…

Scope of Variables in Python

Scope is a visibility which determines whether the variable is accessed by other parts of a code or not. Let’s see an example:

print(num)
print(func(num))

Python Statements(Control Flow)

Mappings are a collection of objects that are stored by a key, unlike a sequence that stored objects by their relative position. A Python dictionary consists of a key and then an associated value. That value can be almost any Python object.

Functions in Python

A function is a block of organized, reusable code which only runs when it is called. You can pass data or parameters into a function.

Syntax to create a function:

def name_of_function(arg1,arg2,arg3):
    # Do coding here
    # Return…
