Well, I had to try it:
>>> float.as_integer_ratio(math.pi);
(884279719003555L, 281474976710656L)
It's not as good as my favorite, due to Arima Yoriyuki:
<http://en.wikipedia.org/wiki/Arima_Yoriyuki>
$ cat pi.bc
#!/usr/bin/bc -lq
scale = 30
print "python: ",884279719003555/281474976710656,"\n"
print "Arima: ",428224593349304/136308121570117,"\n"
print "4*a(1): ",4*a(1),"\n"
print "Wiki: 3.141592653589793238462643383279\n"
quit
$ ./pi.bc
python: 3.141592653589793115997963468544
Arima: 3.141592653589793238462643383275
4*a(1): 3.141592653589793238462643383276
