Python 3.6 8位二进制转十进制

Question

I am making a Python code in Python 3,6 that will prompt the user to input either 2 decimals up to 255 or an 8 bit binary number with the conversion to decimal, getting the user to input the 2 standard decimal numbers is no problem, also the same with getting them to input a binary number, however the once I print the binary conversion, it displays every binary number up to the corresponding number in decimal, lets say I type 11111111, it'd display, 1, 3, 7, 15, 31, etc up to 255

def add2():

    binary = input('enter a number in binary: ')
    decimal = 0
    for digit in binary:
        decimal= decimal*2 + int(digit)

        print ("This is the decimal equivalent" , decimal,)

This is the print result:

That is what my code is and I will attach a picture of what the printed calculation looks like. In the image you can see that it prints 8 times, each bit up to 255, realistically I just want the code to print the corresponding decimal integer, to what bits the user has put in, like for example if they put in 11111111, just print 255.

Answer 1

只需将您的print()指令从for循环中取出，否则它将打印出您回答的每一步。

Answer 2

Your print function is indented so it's in the for loop so remove the space in front of the print function
