Binary to Decimal Updated

Tue, 28 Jan 2025 14:21:03 +1100

In my other blog post ‘Binary to Decimal’, I realized what if I had put in a different number than 1 and 0. I tried putting a 2 and the code still worked. So I will be sharing an updated version, so that you can only put in either 1 or 0. Else there will be an error.

# make a new function
def bintodeci(num):
    reverse = len(num) -1
    exp = 0
    total = 0
    for index in range(reverse, -1, -1):
        # if each number is either 0 or 1 else it'll print out an error.
        if num[index] in '01':
            total += int(num[index]) * (2**exp)
            exp += 1
        else:
            print("Error: Invalid binary number")
            return None
            
    # return the value
    return total

# In case I want to import it
if __name__ == '__main__':
     print(f'The variable __name__ is {__name__}')
     answer = bintodeci("111")
     print(answer)

Binary to Decimal

Thu, 23 Jan 2025 20:33:23 +1100

I’m sharing a program that converts binary to decimal in python.

# make a new function
def bintodeci(num):
    reverse = len(num) -1
    exp = 0
    total = 0
    # range(start, stop, step)
    for digit in range(reverse, -1, -1):
        total += int(num[digit]) * (2**exp)
        exp += 1
    
    # return the value
    return total


answer = bintodeci("11")
print(answer)

sample output:

bai.

Assignment 5: Elements and Indices

Today I had to do another assignment which is to create a python program which prints the elements of a list followed by their corresponding indices. Each element and its index must be on the same line seperated by a space. And if the list is empty, print “Empty List”.

I’m going to make a list called num and put 1 to 4 inside.

num = [1, 2, 3, 4]

Then I’ll use the if statement to do:
