The trace module can be invoked from the command line. It can be
as simple as
python -m trace --count somefile.py ...
The above will generate annotated listings of all Python modules imported
during the execution of somefile.py.
The following command-line arguments are supported:
--trace, -t
Display lines as they are executed.
--count, -c
Produce a set of annotated listing files upon program
completion that shows how many times each statement was executed.
--report, -r
Produce an annotated list from an earlier program run that
used the --count and --file arguments.
--no-report, -R
Do not generate annotated listings. This is useful if you intend to make
several runs with --count then produce a single set
of annotated listings at the end.
--listfuncs, -l
List the functions executed by running the program.
--trackcalls, -T
Generate calling relationships exposed by running the program.
--file, -f
Name a file containing (or to contain) counts.
--coverdir, -C
Name a directory in which to save annotated listing files.
--missing, -m
When generating annotated listings, mark lines which
were not executed with `>>>>>>'.
--summary, -s
When using --count or --report, write a
brief summary to stdout for each file processed.
--ignore-module
Ignore the named module and its submodules (if it is
a package). May be given multiple times.
--ignore-dir
Ignore all modules and packages in the named directory
and subdirectories. May be given multiple times.
