python - Elegant way to remove fields from nested dictionaries -


I had to remove some fields from a dictionary, the keys in this area are on a list, then I type this function: 

  def delete_keys_from_dict (dict_del, lst_keys): "" "Delete the key in lst_keys from the dictionary, repeatedly loop on nested dictionaries." "Dict_foo = dict_del .copy () is used as an iterator to avoid 'dictionary: side-changel' error for fields in dict_foo.keys (): If the field contains lst_keys: del dict_del [field] if type ( Dict_foo [field]) == dict: delete_keys_from_dict (dict_del [field], lst_keys) return dict_del

This code works, but it is not very elegant and I'm sure you Better solution codes can be done in advance. 

  def delete_keys_from_dict (dict_del, lst_keys) For: l Lst_keys: try: del dict_del [k] except for keyError: pass for v in dict_del.values ​​(): If ifinstance (v, dict): delete_keys_from_dict (v, lst_keys) return dict_del

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
