kwargs reserved word in python. What does it mean?
keyword-argument, python
Solution
`**kwargs` means keyword arguments. Its actually not a python keyword, its just a convention, that people follow. That will get all the key-value parameters passed to the function. For example,
def func(*args, **kwargs):
print args, kwargs
func(1, "Welcome", name="thefourtheye", year=2013)
will print
(1, 'Welcome') {'name': 'thefourtheye', 'year': 2013}
Problem
I am using Python trying to figure out a key word and I see the word, "`kwargs`", which I know is some kind of argument in the called function but I can not find what it means or stands for anywhere. For example, this entry in the Python documents says... ``` read_holding_registers(address, count=1, **kwargs) ``` Parameters: ``` address – The starting address to read from count – The number of registers to read unit – The slave unit this request is targeting ``` It looks like a reference to a pointer to pointer but that is all I can tell... This does NOT even use "`**kwargs`" in the parameters list It uses what looks to me like, "`unit`" instead of "`kwargs`". I can NOT seem to find anywhere what `kwargs` means. Maybe it is "Key Word arguments" ? What am I missing here ? Any ideas on help here ? thank you ! boB
