Decimal into Binary converter using python

In this blog you you can learn how to how to make decimal to binary converter program.

process of conversion :-

source code : 

#decimal to binary converter

def dec_bin(dec):                        #define function

    binnum=[0]*dec                        #list created

    i=0                                             #assign i for count

    while dec > 0:                            #while loop

        binnum[i] = dec%2                #logic part 1

        dec = dec//2                            #logic part 2

        i += 1                                      #increase by 1

    for j in range (i-1,-1,-1):                         #for loop for reverse the binary number to p

        print(binnum[j],end="")                    #printing binary number    

dec = int(input("enter the decimal number : "))                #take input through user 

dec_bin(dec)                                                                       #function calling.. 

Sum of all digit of number using python

 Question :

Find sum of all digit of number :-

this problem is solved by two method  :-

1st is without recursion method and 

2nd is using recursion method 

let's start ,

Without recursion method 

step 1 :

make a function with name sumofDigit(num) : and pass the argument which is entered from the user 

def sumofDigit(num):

step 2 :

we use while loop here for checking if num is grater then 0 is show in the code below :-

add=0

while num>0:

if the condition is True then we move to the next step

step 3 :

this step is totally on logic as shown below : -

add  =  add  + num%10

num = num//10

print(add)                #to print the result

step 4 :

in the step you come out from the function and call the function  as shown below : -

num=int (input("enter the number : "));            #take input through user 

sumofDigit(num)                     #function call 

COMPLETE SOURCE CODE 

1st method of without using recursion 

#sum of 4 digit number without recursion

num=int (input("Enter the number : "))

add=0

while num>0:

     add=add+num%10

     num=num//10

print(add)

2nd Method using recursion 

#sum of 4 digit using recurssion

def sdig(num):

    if num==0:

        return 0

    return ((num%10) + sdig(num//10))

num=int (input("Enter the number : "))

print(f"sum of digit of {num} is {sdig(num)}")

Reverse digit using python

 Question :

write a function reverse_number () to return the reverse of the number entered.

Example :

Reverse_number(1234) display 4321

Source code :

def reverse_number (num):

    add=""

    while (num > 0):

        n=num%10                                  # logic 

        num=num//10                                               

        add=str(add)+str(n)

    print(add)

num = int (input("Enter the number : "))

reverse_number(num)

 Instabot

In  this session  we learn how to upload picture using python library called instabot .

How to instabot on your pc .

step 1: 

go to the START, search  cmd then, press enter key

after that your command prompt is open as show in the given picture : -

step 2: 

you have to type pip install instbot and press ENTER  on the command prompt as shown in picture below : -

AFTER doing this all steps then your instabot is successfully installed on your pc . as shown in picture below : -

now go to the OPEN your IDLE and write the code below : -

Source Code

from instabot import Bot

bot=Bot()

bot.login(username= "yout username ",password="your password")

bot.upload_photo("C:/Users/ajay pandit/Desktop/UtubDownloader 18-03-2021 08_17_23.png" ,caption=" write caption here " )

strong number using python

 Strong number is a special number whose sum of factorial of digits is equal to the original number. For example: 145 is strong number. Since, 1! + 4!

IDLE view : 

source code :

#strong number 145

def fact(n):    #calculating factorial 

    if (n>0):

        return (n*fact(n-1))

    else:

        return (1)

#strong number  code

add=0

num=input("enter the number : ")

l=(len(num))

for i in range(0,l):

    add=add+fact(int(num[i]))

if int(num)==add:

    print(f"{num} is strong number ")

else:

    print (f"{num} is not strong number ")

    

prime number using python

 Positive integer greater than 1 which has no other factors except 1 and the number itself is called a prime number. 2, 3, 5, 7 etc. are prime numbers as they do not have any other factors. But 6 is not prime (it is composite) since, 2 x 3 = 6.

num=int(input("enter the numbr : "))

for i in range (2,num):

    if (num%i != 0 ):

        print(f"{num} is  a prime number ")

        break

    else:

        print (f"{num} is not prime number ")

        break;
