num = 500
arr = [0]*50
i = -1
while(num != 0):
i += 1
arr[i] = num % 2
num = math.floor(num / 2)
print("Binary number of 500 (decimal) is ", end="")
for j in range(i, -1, -1):
print(arr[j], end="")

### Output

Binary number of 500 (decimal) is 111110100

num = int(input("Enter a Decimal Number: "));
copyNum = num;
arr = [0]*50
i = -1
while(copyNum != 0):
i += 1
arr[i] = copyNum % 2
copyNum = math.floor(copyNum / 2)
print("Binary number of %d (decimal) is " % num, end="")
for j in range(i, -1, -1):
print(arr[j], end="")
