When working with a namedtuple value returned by an imported module, ._asdict() is not found to be a valid attribute.
My attempted usage :
>>> import os
>>> os.get_terminal_size()
os.terminal_size(columns=120, lines=30)
>>> os.get_terminal_size()._asdict()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'os.terminal_size' object has no attribute '_asdict'
Reading over the source for the os module I noted the following :
terminal_size = namedtuple("terminal_size", "columns lines")
# ...
def get_terminal_size(fallback=(80, 24)):
# ...
return terminal_size(columns, lines)
As the returned value is a namedtuple I would expect it to retain the functionalities this data type provides. I would expect the following :
>>> import os
>>> os.get_terminal_size()
os.terminal_size(columns=120, lines=30)
>>> os.get_terminal_size()._asdict()
{'columns': 120, 'lines': 30}
Despite the leading underscore, this functionality is documented and is commonly utilized. Link to this documentation and the source referenced can be found below.
I am new to namedtuples and I appreciate any guidance. Your time is much appreciated.
