Ken, I don't suppose you have another email address that you sometimes use?
Because if you do, that may be the problem.
If you are subscribed to this list as krush1...@yahoo.com, and you try to send
to it using another email address, you will get bounced. The list software can
only recognize you by your email address.
def General_info():
file4 = open("Genfacts.p", "rb")
This line above is the problem: it tries to open a file which may not exist.
Ginfo = pickle.load(file4)
file4.close()
print('General Information: ')
GinfoKey = input('CatKey: ')
GinfoFact = input('Info: ')
Ginfo[GinfoKey] = GinfoFact # add new key:fact
file4 = open("Genfacts.p", "wb")
pickle.dump(Ginfo, file4)
file4.close()
return(Ginfo)
Try this instead:
def General_info():
try:
file4 = open("Genfacts.p", "rb")
Ginfo = pickle.load(file4)
file4.close()
except IOError:
# Either the file doesn't exist, or something more serious.
# Assume the file doesn't exist.
Ginfo = {} # Start with an empty dict.
print('General Information: ')
GinfoKey = input('CatKey: ')
GinfoFact = input('Info: ')
Ginfo[GinfoKey] = GinfoFact # add new key:fact
file4 = open("Genfacts.p", "wb")
pickle.dump(Ginfo, file4)
file4.close()
return Ginfo
Note: Python experts will probably point out a whole bunch of things I did
wrong in the above. That's deliberate: I didn't want to overload you with too
many changes all at once.
By the way, the shelve module is specifically designed to solve the problem
you are trying to solve here: how to store key:value pairs on disk. Here's a
version using shelve:
import shelve
def get_facts():
facts = shelve.open('facts.db', writeback=True)
print('Please enter a fact: ')
key = input('CatKey: ')
value = input('Info: ')
facts[key] = value
# Make a copy for later use.
d = {}
d.update(facts) # Copy from facts --> d
facts.close()
return d
Good luck!
