Am I doing the right thing for -
- Have a class
- Instantiate the class with 3 parameters
- pickle the class instance
- generate a bytestream (.pkl) using pickle.dump, simply guessing -
as -
---
#!/usr/bin/python
import pickle
class Pickle:
def __init__(self, Parameter1, Parameter2, Parameter3):
self.PM1 = Parameter1
self.PM2 = Parameter2
self.PM3 = Parameter3
with open('/tmp/readfile.pkl', 'wb') as f:
pickle.dump((self.PM1, self.PM2, self.PM3), f)
with open('/tmp/readfile.pkl', 'rb') as f:
self.PM1, self.PM2, self.PM3 = pickle.load(f)
print self.PM1
print self.PM2
print self.PM3
----
but I get an error message as -
-----
$ ./class-test1.py
Traceback (most recent call last):
File "./class-test1.py", line 12, in <module>
pickle.dump((self.PM1, self.PM2, self.PM3), f)
NameError: name 'self' is not defined
