Python Program to Find out How many 1 and 0 in a Given Number

In the previous article, we have discussed Python Program to Enter Basic Salary and Calculate Gross Salary of an Employee
Given a Number and the task is to calculate the count of 1’s and 0’s in a given Number in Python.

Examples:

Example1:

Input:

Given Number = 111000101

Output:

The Count of 0's in a given number =  4
The Count of 1's in a given number =  5

Example2:

Input:

Given Number = 1010101110000

Output:

The Count of 0's in a given number =  7
The Count of 1's in a given number =  6

Program to Find out How many 1 and 0 in a Given Number In Python

Below are the ways to calculate the count of 1’s and 0’s in a given Number:

Using While Loop (Static Input)
Using While loop (User Input)

Method #1: Using While Loop (Static Input)

Approach:

Give the number as static input and store it in a variable.
Take a variable say ones_cnt and initialize its value with 0.
Take another variable say zeros_cnt and initialize its value with 0.
Loop till the given number becomes zero using the while loop.
Calculate the value of the given number modulus 10 (which gives the last digit of the given Number).
Store it in another variable.
Calculate the value of the given number divided by 10 (which removes the last digit of the given number).
Store it in the same variable gvn_number.
Check if the above-obtained value of the given number modulus 10 is equal to 1 using the if conditional statement.
If the statement is true, then increment the value of ones_cnt by 1 and store it in the same variable.
Check if the above-obtained value of the given number modulus 10 is equal to 0 using the if conditional statement.
If the statement is true, then increment the value of zeros_cnt by 1 and store it in the same variable.
Print the values of zeros_cnt, ones_cnt to get the count of 1’s and 0’s in a given Number.
The Exit of the Program.

Below is the implementation:

# Give the number as static input and store it in a variable.
gvn_num = 111000101
# Take a variable say ones_cnt and initialize its value with 0.
ones_cnt = 0
# Take another variable say zeros_cnt and initialize its value with 0.
zeros_cnt = 0
# Loop till the given number becomes zero using the while loop.
while gvn_num:
    # Calculate the value of the given number modulus 10 (which gives the last digit of the given Number).
    # Store it in another variable.
    remindr = gvn_num % 10
# Calculate the value of the given number divided by 10 (which removes the last digit of the given number).
# Store it in the same variable gvn_number.
    gvn_num = int(gvn_num/10)
# Check if the above-obtained value of the given number modulus 10 is equal to 1
# using the if conditional statement.
    if remindr == 1:
         # If the statement is true, then increment the value of ones_cnt by 1 and
        # store it in the same variable.
        ones_cnt = ones_cnt+1
# Check if the above-obtained value of the given number modulus 10 is equal to 0
# using the if conditional statement.
    if remindr == 0:
     # If the statement is true, then increment the value of zeros_cnt by 1 and store it in
        # the same variable.
        zeros_cnt = zeros_cnt+1
 # Print the values of zeros_cnt ,ones_cnt to get the count of 1's and 0's in
# a given Number.
print("The Count of 0's in a given number = ", zeros_cnt)
print("The Count of 1's in a given number = ", ones_cnt)

Output:

The Count of 0's in a given number =  4
The Count of 1's in a given number =  5

Method #2: Using While loop (User Input)

Approach:

Give the number as user input using the int(input()) function and store it in a variable.
Take a variable say ones_cnt and initialize its value with 0.
Take another variable say zeros_cnt and initialize its value with 0.
Loop till the given number becomes zero using the while loop.
Calculate the value of the given number modulus 10 (which gives the last digit of the given Number).
Store it in another variable.
Calculate the value of the given number divided by 10 (which removes the last digit of the given number).
Store it in the same variable gvn_number.
Check if the above-obtained value of the given number modulus 10 is equal to 1 using the if conditional statement.
If the statement is true, then increment the value of ones_cnt by 1 and store it in the same variable.
Check if the above-obtained value of the given number modulus 10 is equal to 0 using the if conditional statement.
If the statement is true, then increment the value of zeros_cnt by 1 and store it in the same variable.
Print the values of zeros_cnt, ones_cnt to get the count of 1’s and 0’s in a given Number.
The Exit of the Program.

Below is the implementation:

# Give the number as user input using the int(input()) function and store it in a variable.
gvn_num = int(input("Enter some random Number = "))
# Take a variable say ones_cnt and initialize its value with 0.
ones_cnt = 0
# Take another variable say zeros_cnt and initialize its value with 0.
zeros_cnt = 0
# Loop till the given number becomes zero using the while loop.
while gvn_num:
    # Calculate the value of the given number modulus 10 (which gives the last digit of the given Number).
    # Store it in another variable.
    remindr = gvn_num % 10
# Calculate the value of the given number divided by 10 (which removes the last digit of the given number).
# Store it in the same variable gvn_number.
    gvn_num = int(gvn_num/10)
# Check if the above-obtained value of the given number modulus 10 is equal to 1
# using the if conditional statement.
    if remindr == 1:
         # If the statement is true, then increment the value of ones_cnt by 1 and
        # store it in the same variable.
        ones_cnt = ones_cnt+1
# Check if the above-obtained value of the given number modulus 10 is equal to 0
# using the if conditional statement.
    if remindr == 0:
     # If the statement is true, then increment the value of zeros_cnt by 1 and store it in
        # the same variable.
        zeros_cnt = zeros_cnt+1
 # Print the values of zeros_cnt ,ones_cnt to get the count of 1's and 0's in
# a given Number.
print("The Count of 0's in a given number = ", zeros_cnt)
print("The Count of 1's in a given number = ", ones_cnt)

Output:

Enter some random Number = 1001101
The Count of 0's in a given number = 3
The Count of 1's in a given number = 4
