Passing a non-iterable to list.extend ()
- by JS
Hello,
I am creating a public method to allow callers to write values to a device, call it write_vals() for example.
Since these values will by typed live, I would like to simplify the user's life by allowing them type in either a list or a single value, depending on how many values they need to write. For example:
write_to_device([1,2,3])
or
write_to_device(1)
My function would like to work with a flat list, so I tried to be clever and code something like this:
input_list = []
input_list.extend( input_val )
This works swimmingly when the user inputs a list, but fails miserably when the user inputs a single integer:
TypeError: 'int' object is not iterable
Using list.append() would create a nested list when a list was passed in, which would be an additional hassle to flatten.
Checking the type of the object passed in seems clumsy and non-pythonic and wishing that list.extend() would accept non-iterables has gotten me nowhere. So has trying a variety of other coding methods.
Suggestions (coding-related only, please) would be greatly appreciated.
