Yes. It's already posted; next time have a look at the concise library reference: http://docs.python.org/lib/typesmapping.html > This would be possible: > > keys_of_names = names.keys() > L = len(keys_of_names) > > for i in range(L): > if keys_of_names[i] == name_key: > print 'found' Coming in from Java? 8) Iterating through something using len(X) is quite rare in Python. If we had no simple "key in dict" test, I'd write the above as: for key in names.keys(): if key == name_key: print "found" break else: print "not found" (It would even suffice to write "for key in names".)
