two embedded problem. one maybe is python bug.

[yy x]

hi,all,
 
 
 
the content of a.py :
#coding:gb2312#/usr/local/bin/pythonimport randomprint random.randint(0,10)
 
the c program:

#include int main(){    Py_Initialize();    PyRun_SimpleString("import sys");    PyRun_SimpleString("sys.path.append('.')");
    PyRun_SimpleString("import a");    Py_Finalize();
    return 0;}
the gcc cmd line:
   g++ -o a a.c -I/usr/local/include/python /usr/local/lib/libpython -lm -lpthread -ldl
First problem:
    when i run the a, the error msg is :
  Traceback (most recent call last):  File "", line 1, in ?  File "./a.py", line 1SyntaxError: encoding problem: with BOM
 
but if i first import a.py through the python cmd line.  This problem disappears.(but second problem appears)(now  I think  the a import a.pyc not a.py)
I think  it's python bug, isn't it?
Second problem,
   Traceback (most recent call last):  File "", line 1, in ?  File "a.py", line 3, in ?    import random  File "/usr/local/lib/python2.4/random.py", line 44, in ?
    from math import log as _log, exp as _exp, pi as _pi, e as _eImportError: /usr/local/lib/python2.4/lib-dynload/math.so: undefined symbol: PyExc_OverflowError.
 
Pls give me some advice, i am crazy.thanks

How to call a mothod in a class by the method name string and the instance?

[yy x]

hi, all:
  for example, the following class:
class test:    def funca(self):    print  "in funca"
    def funcb(self):    print  "in funcb"
t = test()
t.funca()
 
    In the plain way,  i will excute the funca by the code "t.funca() ",
but if i wanna to excute the funca by "t" and string "funca", how will i do?
 
maybe the idea is similiar to "call(t, "funca") ".
 
best regards.

how to transfer a python object to other computer?

[yy x]

    Hey, all.Now I wanna to transfer a object to other computer, Maybe I could serialize the object to a file by pickle moudle, then send the file and get it from the file.But I think the efficency is awful, because the disk io is very slow. 

 Someone could do me a favor to give me some idea?
 
Best Wish.
