help accesing info from dict/db

[neil1811]

Hi Guys,

I can populate my dictionary with the following code..
This is fine and the code goes to the database.

import e32dbm

# Open the dictionary
d = e32dbm.open(u"c:\\python\\People.dict", "c")

# Add the default entries into the dictionary
People = {  'John'                 : {"Age": "20",
				       "Address"    : "blah"}, 
	    'Jim'                  : {"Age": "31",
				       "Address"    : "blah2"},
	    'Paul'                 : {"Age": "42",
				       "Address"    : "blah3"},
            'Peter'                 : {"Age": "23",
				       "Address"    : "blah4"}}

# Close the db
d.close()

But i cannot retrieve this information i want when running my other script..

i reopen the db and attempt to print something and i get errors.

heres my code to try fetch some dictionary entry in my other script

import e32dbm

# Open it again , in write mode
dd = e32dbm.open(u'c:\\python\\People.dict')

for k in dd.keys():
   print k 
   print dd[k]

dd.close()

Any help on how i can just do this simple task!!

Thanks you

EDIT: Are you sure the information gets written to the file People.dict? It looks to me like you just assign the dictionary to the variable People, but don't write it to the file.

I've tried your scripts. I don't get any errors on the second one, but nothing happens. I just don't know why, the code looks fine.
Anyway, I have an alternative:

Script 1:

import e32, appuifw, codecs

def quit():app_lock.signal()
appuifw.app.exit_key_handler=quit

# Open the dictionary in write mode
d = codecs.open(u"c:\\python\\People.dict", "w", "utf_8")

# Add the default entries into the dictionary
People = {'John' : {"Age": "20", "Address" : "blah"}, 
          'Jim' : {"Age": "31", "Address" : "blah2"},
          'Paul' : {"Age": "42", "Address" : "blah3"},
          'Peter' : {"Age": "23", "Address" : "blah4"}}

People="People="+str(People)

d.write(People)

# Close the db
d.close()

app_lock=e32.Ao_lock()
app_lock.wait()

Script 2:

import e32, appuifw, codecs

def quit():app_lock.signal()
appuifw.app.exit_key_handler=quit

# Open it again , in read mode
dd = codecs.open(u"c:\\python\\People.dict", "r", "utf8")

t=dd.read()
exec(t)

for k in People.keys():
   print k 
   print People[k]

dd.close()

app_lock=e32.Ao_lock()
app_lock.wait()

Basically all I did was put the dictionary assignment in a text file as a string and then execute it in the second script.
Sorry this is not the answer you were looking for, but I can't figure out why your code doesn't work.
