When passing kwargs into a function, it expects to find the exact variable name in the list. If instead your dictionary keys were stringa, integera, and floata the function would work without problem. So you either need to change your function variable names or change the key names in your dictionary to get this to … Read more
Should I just continue to use the @param keyword? Yes. YARD recognizes keyword arguments. Use @param to document a single method parameter (either regular or keyword) with a given name, type and optional description: # @param query [String] The search string # @param exact_match [Boolean] whether to do an exact match # @param results_per_page [Integer] … Read more
This does the job: stats = { ‘copied’: 5, ‘skipped’: 14 } print( ‘Copied: {copied}, Skipped: {skipped}’.format( **stats ) ) #use ** to “unpack” a dictionary For more info please refer to: http://docs.python.org/py3k/library/string.html#format-examples and http://docs.python.org/py3k/tutorial/controlflow.html#keyword-arguments
Bare * is used to force the caller to use named arguments – so you cannot define a function with * as an argument when you have no following keyword arguments. See this answer or Python 3 documentation for more details.
As of Python 3.6, the keyword argument order is preserved. Before 3.6, it is not possible since the OrderedDict gets turned into a dict. The first thing to realize is that the value you pass in **example does not automatically become the value in **kwargs. Consider this case, where kwargs will only have part of … Read more
For Python versions < 3.5, you need to place the **kwargs variable keyword argument last: f(c=3, **pre_defined_kwargs) See the Calls expression syntax; in all forms of the grammar the “**” expression rule is placed last. In other words, using anything after the **expression syntax is a syntax error. If you want to update the dictionary … Read more
No, there is no way to do it in Python code with this signature — if you need this information, you need to change the function’s signature. If you look at the Python C API, you’ll see that the actual way arguments are passed to a normal Python function is always as a tuple plus … Read more
Primary key attribute usually assigned by the database when the instance saved first time. So you can use something like if instance.pk is None
The general idea is: def func(arg1, arg2, …, kwarg1=default, kwarg2=default, …, *args, **kwargs): … You can use as many of those as you want. The * and ** will ‘soak up’ any remaining values not otherwise accounted for. Positional arguments (provided without defaults) can’t be given by keyword, and non-default arguments can’t follow default arguments. … Read more
For Python 3 users: You can iterate through kwargs with .items() subject = obj.subject body = obj.body for key, value in kwargs.items(): subject = subject.replace(‘[%s]’ % key.toupper(), value) body = body.replace(‘[%s]’ % key.toupper(), value) return (subject, body, obj.is_html) For Python 2 users: You can iterate through kwargs with .iteritems(): subject = obj.subject body = obj.body … Read more
