How to print python commands automatically?

[Peng Yu]

Hi,

In bash, set -v will print the command executed. For example, the
following screen output shows that the "echo" command is printed
automatically. Is there a similar thing in python?

~/linux/test/bash/man/builtin/set/-v$ cat main.sh
#!/usr/bin/env bash

set -v
echo "Hello World!"
~/linux/test/bash/man/builtin/set/-v$ ./main.sh
echo "Hello World!"
Hello World!



Regards,
Peng

I'm not able to get the mixing of the python command screen output on
stdout. Is there a combination of options for this purpose?

~/linux/test/python/man/library/trace$ cat main1.py
#!/usr/bin/env python

def f():
print "Hello World!"

f()
~/linux/test/python/man/library/trace$ cat main.sh
#!/usr/bin/env bash

python -m trace --count -C . main1.py -t

~/linux/test/python/man/library/trace$ ./main.sh
Hello World!
~/linux/test/python/man/library/trace$ cat main1.cover
#!/usr/bin/env python

1: def f():
1: print "Hello World!"

1: f()

Try with just --trace?


C:\ramit>python.exe -m trace test.py
C:\ramit\Python27\lib\trace.py: must specify one of --trace, --count, --report, --listfuncs, or --trackcalls

C:\ramit>python -m trace --trace test.py
--- modulename: test, funcname: <module>
test.py(2): def f():
test.py(5): f()
--- modulename: test, funcname: f
test.py(3): print "Hello World!"
Hello World!
--- modulename: trace, funcname: _unsettrace
trace.py(80): sys.settrace(None)

I have to explicitly specify the modules I want to ignore. Is there a
way to ignore all the modules by default?

~/linux/test/python/man/library/trace/import$ cat.sh main.py main.sh test.py
==> main.py <==
#!/usr/bin/env python

import test

test.test()


==> main.sh <==
#!/usr/bin/env bash

python -m trace --trace main.py


==> test.py <==
def test1():
print "Hello World!"

def test():
test1()

~/linux/test/python/man/library/trace/import$ python -m trace --trace
--ignore-module=test main.py
--- modulename: main, funcname: <module>
main.py(3): import test
main.py(5): test.test()
Hello World!
--- modulename: trace, funcname: _unsettrace
trace.py(80): sys.settrace(None)
