equivalent of bash "set -x" in Python

[TP]

Hi everybody,

I am interested in having the possibility to print every Python commands in
a script (for didactic purpose).
So I am looking for some sort of equivalent of bash "set -x".
Does it exist?

Thanks

Julien

What do you mean by "command" ?

Not exactly. However, defining an appropriate function and passing it
to sys.settrace() would be the closest analogue:
http://docs.python.org/library/sys.html#sys.settrace

You could also step through your code manually using the debugger:
http://docs.python.org/library/pdb.html

Cheers,

For example, print statements, but it could extend to class definitions,
etc. I am going to examine the solution given by Chris.

Cheers,
