def vmod(a , b ):
.r1 = b
.r2 = a
. m1 = 0
.m2 = 1
.q = Int(r1 / r2)
.r3 = r1 - q * r2
.m3 = m1 - q * m2
.while r3 != 0:
...r1 = r2
...m1 = m2
...r2 = r3
...m2 = m3
...q = Int(r1 / r2)
...r3 = r1 - r2 * q
...m3 = m1 - m2 * q
.If r2 == 1:
...If m2 < 0:
.....return( m2 + b)
...Else:
.....return( m2 )
.Else:
...return( -r2 )
When I attempt to run this function from the shell run menu,
I get the message
syntax error
and it highlights r2
in the line
.If r2 == 1:
However if I
use the eval function in the shell, I get
>>> eval("factor30")
<module 'factor30' from 'c:\math\factoring\factor30.pyc'>
>>>
no error message.
and when I use help to look at the associated module,
this function is not listed. It must be because of the syntax error.
>>> help(factor30)
Help on module factor30:
NAME
factor30
FILE
c:\math\factoring\factor30.py
FUNCTIONS
factor(z)
factor0(z)
gcd(a, b)
ifprime(z)
ksqrt(j)
test(tv)
transfac(v)
Give me some hint for why this is happening.
The periods at the beginning of each line represents beginning spaces.
