Write a python program to convert a given binary number into its equivalent decimal.

Question

Test cases: Input: 110101  Output: 53

# Python3 program to convert

# binary to decimal

# Function to convert

# binary to decimal

def binaryToDecimal(n):

    num = n;

    dec_value = 0;

    # Initializing base

    # value to 1, i.e 2 ^ 0

    base = 1;

    temp = num;

    while(temp):

        last_digit = temp % 10;

        temp = int(temp / 10);

        dec_value += last_digit * base;

        base = base * 2;

    return dec_value;

# Driver Code

num = 10101001;

print(binaryToDecimal(num));

Answer 1

the code you've posted works fine if you remove all invisible illegal characters: I guess that's not your attempt, but a ready made solution wich you have copy-pasted from somewhere on internet by beeing too lazy to copy by typing it ;P

however, it doesn't return 53 because you doesn't give it the test case input... but replacing the num initialization with the correct value given in test case it return 53 as expected ^^
