There is no such thing as "the netCDF4 variable" in Python -- it is not a
built-in part of the language, and therefore there is no built-in feature
for manipulating it.
You are going to have to be more specific about what you want than just
"how do I modify a variable with for loops?".
My wild guess is that you have some sort of config file which includes a
field called "netCDF4" and you want to update it in place. We can't tell
you how to do this without knowing what the config file is -- is it an
INI file, XML, JSON, YAML, Unix-style rc file, a binary pickle, or
