Request for help from Python beginner:

I don't want you to do the work for me, just some help to know where my mistakes are and how to correct them.

I am trying to code a program to convert any decimal number into binary. In the case of an infinitely repeating decimal number, the number should terminate at 5 significant digits.

I have nearly all of the code completed, but have encountered a couple of issues.

Here's my code:

```
numint = ""
numfrac = ""
values = ""
binint = ""
binfrac = ""
number = raw_input("Input a number")
values = number.split(".")
integer = int(values[0])
while integer >= 1:
intremainder = integer % 2
integer = integer / 2
intremainder = str(intremainder)
binint = binint + intremainder
binint = binint[::-1]
if "." in number:
fraction = float(values[1]) / (10 ** len(values[1]))
fraction1 = float(fraction) * 2
fraction1 = str(fraction1)
binfrac1 = fraction1[0]
if "1" in binfrac1:
fraction1 = float(fraction1)
fraction1 - 1
binfrac1 = str(binfrac1)
fraction2 = float(fraction1) * 2
fraction2 = str(fraction2)
binfrac2 = fraction2[0]
if "1" in binfrac2:
fraction2 = float(fraction2)
fraction2 - 1
binfrac2 = str(binfrac2)
fraction3 = float(fraction2) * 2
fraction3 = str(fraction3)
binfrac3 = fraction3[0]
if "1" in binfrac3:
fraction3 = float(fraction3)
fraction3 - 1
binfrac3 = str(binfrac3)
fraction4 = float(fraction3) * 2
fraction4 = str(fraction4)
binfrac4 = fraction4[0]
binfrac4 = str(binfrac4)
if "1" in binfrac4:
fraction4 = float(fraction4)
fraction4 - 1
binfrac4 = str(binfrac4)
fraction5 = float(fraction4) * 2
fraction5 = str(fraction5)
binfrac5 = fraction5[0]
binfrac5 = float(binfrac5)
if "1" == binfrac5:
fraction5 = float(fraction5)
fraction5 - 1
binfrac5 = str(binfrac5)
binfrac = binfrac1 + binfrac2 + binfrac3 + binfrac4 + binfrac5
print binint + "." + binfrac
```

Yes, my code isn't particularly elegant. I intend to shorten a lot of it with a while loop, once I get this code working.

My issues are that the if statements that would subtract 1 from the fraction value if the fraction value is greater than 1 don't work.

My second problem is that in the final converted number, I end up with multiple decimal points. I suspect this is a problem with one of my "fraction * 2" lines, but don't know what to do to correct it.
