Default dict keys to avoid KeyError
You can use your_dict.get(key, "default value") instead of directly referencing a key.
Don't use the "default" argument name. For example, if we want 1.0 as default value,
rank = dict.get(key, 1.0)For more details:TypeError: get() takes no keyword arguments
If you can't define a default value and want to do something else (or just omit the entry):
if key in dict: rank = dict[key]else: # do something or just skip the else block entirely
