Python Program to Find Number of Integers From 1 to n Contains Digits 0’s

Python program to find and count the number of occurrences of 0’s in integers from 1 to N; In this tutorial, you will learn how to find and count integers from 1 to N contain 0’s and 1’s as digits.

How to check if a number contains 0’s digit From 1 to N in python

• Python Program 1: Find the number of integers from 1 to n which contains digits 0’s
• Python Program 2: Find the number of integers from 1 to n which contains digits 0’s
• Python Program 3: Find the number of integers from 1 to n which contains digits 0’s and 1’s

Python Program 1: 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 2: 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 

# 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))

.box-4-multi-260{border:none!important;display:block!important;float:none!important;line-height:0;margin-bottom:15px!important;margin-left:auto!important;margin-right:auto!important;margin-top:15px!important;max-width:100%!important;min-height:250px;min-width:250px;padding:0;text-align:center!important;width:100%}

Output

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

Python Program 3: Find the number of integers from 1 to n which contains digits 0’s and 1’s

# 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
