# Python Program to find whether a no is power of two

In this article, we will learn about the solution to the problem statement given below.

**Problem statement **− We are given a number, we need to check that the number is a power of two or not.

We can solve this using two approaches as discussed below.

## Approach 1: Taking the log of the given number on base 2 to get the power

### Example

# power of 2 def find(n): if (n == 0): return False while (n != 1): if (n % 2 != 0): return False n = n // 2 return True # Driver code if(find(98)): print('Yes') else: print('No')

### Output

No

## Approach 2: Using the logical statements

### Example

# power of 2 def find(x): # if x is 0 or not return (x and (not(x & (x - 1))) ) # Driver code if(find(98)): print('Yes') else: print('No')

### Output

No

## Conclusion

In this article, we have learned how we can check that the given number is a power of two.
