Hello,
Can not dump class object created on runtime.
Is there anybody can help me? Thank.
Following is testing code:
import pickle
from new import classobj
class A:
def __str__(self):
return self.__class__.name
if __name__ == "__main__":
c = classobj('B', (A, ), {}) # create class obj on runtime
print c
print pickle.dumps(c) # get dump string
Bellows are outputs:
__main__.B
Traceback (most recent call last):
File "C:\USERS\train\_work\test\test.py", line 11, in <module>
print pickle.dumps(c)
File "c:\USERS\train\Python25\lib\pickle.py", line 1366, in dumps
Pickler(file, protocol).dump(obj)
File "c:\USERS\train\Python25\lib\pickle.py", line 224, in dump
self.save(obj)
File "c:\USERS\train\Python25\lib\pickle.py", line 286, in save
f(self, obj) # Call unbound method with explicit self
File "c:\USERS\train\Python25\lib\pickle.py", line 748, in save_global
(obj, module, name))
pickle.PicklingError: Can't pickle <class __main__.B at 0x00AF4CF0>: it's
not found as __main__.B
