Just a couple of "issues" that can be fixed as follows:
import pickle
class DemoClass:
def __init__(self):
self.title = ["Hello", "Goodbye"]
def WriteToFile(self, path):
fw = file(path, "w")
pickle.dump(self.title, fw)
fw.close()
if __name__=='__main__':
path='\\test.txt'
x = DemoClass()
x.WriteToFile(path)
Notes:
1) You have to call (follow by parenthesis) DemoClass() to get an instance.
What you got was a pointer (x) to the DemoClass not an instance of
DemoClass.
2) Same for WriteToFile()
3) Probably best to move the path to main and always pass it into
WriteToFile.
