New submission from anatoly techtonik:
I always thought that subprocess is replacing all other methods of executing
external programs from Python and it is a preferred way. Perhaps I was not
attentive that people isolate:
os.system
os.spawn*
os.popen*
and
os.exec*
While subprocess replaces three first, it doesn't do this with the last one.
The documentation should mention this in the header block. Proposed edit:
...
replace several other, older modules and functions, such as:
os.system
os.spawn*
os.popen*
popen2.*
commands.*
+ Note that it doesn't replace other ways of executing external
+ processes from Python, such as:
+
+ os.exec*
Information about how the subprocess module can be used
...
