You mean something like this ...
$ cat fibo.py
# Fibonacci numbers module
# My Python module
def fib(n): # write Fibonacci series up to n
a, b = 0, 1
while b < n:
print b,
a, b = b, a+b
def fib2(n): # return Fibonacci series up to n
result = []
a, b = 0, 1
while b < n:
result.append(b)
a, b = b, a+b
return result
... you need a script like this ...
$ cat runfib.py
#!/usr/bin/python
import fibo
fibo.fib(1000)
print "\n"
print fibo.fib2(100)
... and here's a Perl wrapper ...
$ cat runfib.pl
#!/usr/bin/perl
print `./runfib.py`;
... see this works like so ...
$ ./runfib.pl
1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987
[1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89]
