Where's the Error?
I'm trying to run the following program on my Prime (both emulator and physical) and it gives me a syntax error in line 9. I've been looking at it and looking at it and I can't see the error. What am I doing wrong?

Code:
#PYTHON name from math import * t=eval("ticks()") loops=1000 for i in range(0,loops):   r0=10   while True:     x=r0      x+=1     x-=4.567ᴇ−4     x+=70     x-=69     x*=7     x/=11     r0-=1     if r0<=0:       break   x=log(x)   x=sin(x)   x=sqrt(x)   x=sqrt(x) print(x) t=(eval("ticks()")-t)/1000 print("Index:",34/t*loops)  #end    EXPORT calcperf() BEGIN   PYTHON(name); END;

RE: Where's the Error?
With a few changes your program runs and returns:

0.880981899968678
Index: 1172413.79310345

1. add 'from hpprime import *' at the beginning
2. replace the 'ᴇ−' on line 9 by standard 'E-' letters, it seems that the special character codes used by the Prime for E and minus signs are not supported by Python.

Code:
#PYTHON name from math import * from hpprime import * t=eval("ticks()") loops=1000 for i in range(0,loops):   r0=10   while True:     x=r0      x+=1     x-=4.567E-4     x+=70     x-=69     x*=7     x/=11     r0-=1     if r0<=0:       break   x=log(x)   x=sin(x)   x=sqrt(x)   x=sqrt(x) print(x) t=(eval("ticks()")-t)/1000 print("Index:",34/t*loops)  #end  EXPORT calcperf() BEGIN   PYTHON(name); END;

Thank you!
Now that you've solved it. I have to say of course! I should have known the ticks function is found in the hpprime module but the exponent error is more subtle. It makes sense, though.
