python program to count integers from 1 to N contains 0’s and 1’s as digits; Through this tutorial, i am going to show you how to count integers from 1 to N contains 0’s and 1’s as digits in python program.

In this tutorial, i will write a python program to input an integers from 1 to N and check if it contains any zero 0 and one 1 in it.

## Python Program to Find integers from 1 to N Contains 0’s and 1’s as Digits

- Python Program Find the number of integers from 1 to n which contains digits 0’s
- Python Program Count the number of integers from 1 to n which contains digits 0’s using For Loop
- Python Program Count the number of integers from 1 to n which contains digits 0’s and 1’s using Function

### Python Program Find the number of integers from 1 to n which contains digits 0’s

# Python Program to Find the number of integers from 1 to n which contains digits 0's # input the value of N n=int(input('Enter the value of n: ')) s=str(n) z=str(0) if z in s: print('Zero is found in {}'.format(n)) else: print('Zero is not found in {}'.format(n))

**Output**

Enter the value of n: 10 Zero is found in 10

### Python Program Count the number of integers from 1 to n which contains digits 0’s using For Loop

# Python Program to Find the number of integers from 1 to n which contains digits 0's # enter the value of N n=int(input('Enter the value of n: ')) c=0 z=str(0) for j in range(1,n+1): if z in str(j): c+=1 print('{} number has zero as digits up to {}.'.format(c,n))

**Output**

Enter the value of n: 50 5 number has zero as digits up to 50.

### Python Program Count the number of integers from 1 to n which contains digits 0’s and 1’s using Function

# Python Program to Find the number of integers # from 1 to n which contains 0's and 1's only n=int(input('Enter the value of n: ')) def countNumbers(x, n): # If number is greater than n if x > n : return 0 # otherwise add count this number and # call two functions return (1 + countNumbers(x * 10, n) + countNumbers(x * 10 + 1, n)) # Driver code if __name__ == '__main__': print('The count is ', countNumbers(1, n));

**Output**

Enter the value of n: 200 The count is 7
