Python Comments: A comment in python starts with the hash character(#). Comments are in the source code for humans to read, not for computers to execute. Example: #This is a comment Types of Python comments: 1)Single lined comment 2)Multi lined comment 3)Inline comments Single lined comment: In case user want to specify a single line comment,then comment must start with #. Example: int a=10 #here a is a variable. print("Hello,world") print(a) Output: Hello,world 10 Multi lined comments: Multi lined comment can be given inside triple quotes. Example: ''' This is multiline comment in python''' Inline comments: If a comment is placed on the same line as a statements,it is called an inline comments. Similar to the block comments, an inline comments beigns with a single hash(#) sign and followed by a space and comment. Example: N=10 n+=1 # increase n by 1

Function: It is difficult to maintain large scale program and the identification of the programming gets harder. The best way to create programming application is to divide a big program in small module and repeatedly call this module within program with the help of function and entire program can be devide into small independent modules. A function is the self contained block of one or more statement that perform a special task when called. This improve the code readability as well as flow of execution and small modules can be managed easily. Syntax: def function_name (list_parameter): statement(s) the syntax for the python contains header and the body. The function header begins with the header 'def' followed by the function name and arguments are optional. the body contents the statement to be executed and function will be executed only when it is being called. Example: Write a python program to display a simple message Source ...

Dictionary ({}) Python provide dictionary structure to deal with key and value as pair. It is a container which contains data in pair of '{ }'. The pair key and value is known as Item. The key and value must be separated by ':' and each pair of item is separated by ' , '. Different item s are enclosed within '{ }' and this create dictionary Example: D={101:'AAA',102:'BBB',103:'CCC'} print(D) output: {101:'AAA',102:'BBB',103:'CCC'} The value in the dictionary are mutable i.e it can be change however the key is immutable and must be unique for every item. The key is used to access the specific value. The values can be updated but the key can not be changed. The dictinary is also known as Associated Array. Example: Create a program for dictionary and print any two value using its key and update a value using key and print again. a={name:...
