Basic Binary to Decimal Conversion Program not working (Python)

Question

I tried writing a basic program that converted binary to decimal. However, it's not working. Where did I go wrong? What am I missing. Thanks for the help in advance.

n=int(raw_input(' '))
while n = 1:
 k = n % 10
 z= 0
 w=0
 w = k * (pow ( 2, z)) + w
 z = z+1
 n/10
print w

• mhlester: can you show an example of how it's not working? are you getting an error? if so, what's the traceback?
• mhlester: also, do you know about int(number, base)? int('10010', 2) == 18
• Shahaed: It takes a long time to run, no real output when running a small number like 1011 in 5 minutes
• Shahaed: @mhlester How would I use that to convert a user input? EDIT: GOT IT
• user2555451: @user3281550 - He's saying that your whole script can be reduced to just: print int(raw_input(' '), 2)

Answer 1

First of all, you used = for a comparison test. Instead, I think that you want to use != (not equal):

while n != 1:

= is only used for assignment.

Also, the line:

n/10

does nothing. Instead, it should be:

n /= 10

which is equivalent to:

n = n / 10
