Python Bin | Count total bits in a number
Given a positive number n, count total bit in it.
Examples:
Input : 13 Output : 4 Binary representation of 13 is 1101 Input : 183 Output : 8 Input : 4096 Output : 13
We have existing solution for this problem please refer Count total bits in a number link. We can solve this problem quickly in Python using bin() function. Convert number into it’s binary using bin() function and remove starting two characters ‘0b’ of output binary string because bin function appends ‘0b’ as prefix in output string. Now print length of binary string that will be the count of bits in binary representation of input number.
Python3
# Function to count total bits in a numberdef countTotalBits(num): # convert number into it's binary and # remove first two characters 0b. binary = bin(num)[2:] print(len(binary))# Driver programif __name__ == "__main__": num = 13 countTotalBits(num) |
Output:
4
