KeyError: '13'
I am trying to run a python program. It is giving the KeyError: '13'. I have no clue regarding this error. this is the python code relevant to the error: dpi = 100 bold = 0 italic = 0 mono = 0 comment = dbname = font.db for o, a in opts: if o == '-b': bold = 1 if o == '-i': italic = 1 if o == '-m': mono = 1 if o == '-d': dpi = int (a) if o == '-c': comment = string.join (string.split (a), ) if o == '-g': dbname = a fontname = args[0] pixel_size = int (args[1]) point_size = int (pixel_size * 72.27 / dpi + 0.5) # Approximate average glyph width. avg_width = pixel_size * 17 / 24 db = anydbm.open (dbname, r) codes = loads (db [str (pixel_size)]) And the error is : python2 ../../../mk_bdf.py -c Converted from fonts of Computer Modern family (C) 1979-1985 Donald E. Knuth and others. -b 'TeX Sans' 13 tex09sb.bdf Traceback (most recent call last): File ../../../mk_bdf.py, line 108, in module codes = loads (db [str (pixel_size)]) File /usr/lib/python2.7/bsddb/__init__.py, line 270, in __getitem__ return _DeadlockWrap(lambda: self.db[key]) # self.db[key] File /usr/lib/python2.7/bsddb/dbutils.py, line 68, in DeadlockWrap return function(*_args, **_kwargs) File /usr/lib/python2.7/bsddb/__init__.py, line 270, in lambda return _DeadlockWrap(lambda: self.db[key]) # self.db[key] KeyError: '13' Anybody please help me in running the program. -- http://mail.python.org/mailman/listinfo/python-list

There is no record with the key 13 in the font.db database, and therefore the script fails with the aptly named KeyError. (The database interface is modeled after Python's dictionary, so the handling is similar) And the error is : python2 ../../../mk_bdf.py -c Converted from fonts of Computer Modern family (C) 1979-1985 Donald E.

For now you can ignore the code in the traceback which may be a bit intimidating to a newbie. It contains lines from the implementation of the database interface. Instead have a look at the keys that are in the database with db = anydb.open(font.db) for key in db: print key and then decide if you to need to change the lookup key or to add records to the database. -- http://mail.python.org/mailman/listinfo/python-list

How can I add recors to the database? The Python part of the answer is db[some_key] = some_value but I fear that won't help. Google suggests you are struggling with the metatype project If so, there seems to be a corresponding mk_db.py that you can use. I don't know anything about metatype, but the comment in mk_db.py at http://metatype.cvs.sourceforge.net/viewvc/metatype/metatype/mk_db.py?revision=1.3view=markup tells to run it like so: find . -name '*.ugs' | python mk_db.py -a glyphlist -o dbmfile Perhaps you ran it, but there weren't any *.ugs files? -- http://mail.python.org/mailman/listinfo/python-list

I got metatype compiled.
