If it is in the sys.path you should import it: *import ex1*.
Then execute something like *ex1.main()* if you did a main().
Other python */ex.py* should world.

I've never tried this from Python but
#include
fd = open("/dev/dvb/adapter1/frontend0", O_RDWR)
Notice the fd - that means file descriptor not file pointer.
So ioctl takes a file descriptor in C and

So? str.find() does the same thing. It guarantees to only return 0 or
positive indexes if it finds the substring, and only returns -1 to
indicate not found.

Hello to all. I'm working on writing a tool that will control a piece of

configure and tune a DVB-S receiver on Linux.
Just for starters, I want to try opening the frontend and setting the LNB
voltage. An example in C:

after tests I get the following:

Ok I find a solution (need to test it) that seems correct:
Suppose we have a python file mySourceFile with this setting:
EntryTextName = "myName"
EntryTextMail = "mym...@gmail.com"
In the calling script or main python file we could define a function
sourceConfigGui as follow:

You have a minus sign in your variable name - at least thats
how Python sees

When debugging this kind of thing insert a raw_input() statement
in the loop(to force a pause) and just before it print out the key

Another approach,

alternatively you can use the lambda , reduce function for summing up all
the numbers in a list for e.g:-
lis = [1,2,3,4,5]
p = reduce(lambda x,y : x+y, lis)
p will have the value = 15.

Hello,

Now rewrite the count_letters function so that instead of traversing the
string, it repeatedly calls find (the version from Optional parameters), with
the optional third parameter to locate new occurences of the letter being
counted.
And I have this
