""" Modifications to the standard profile.py API.
The standard profile.run() method in the Python library does not provide
access to variables available to the code snippet during a run. For
example, the following fails:
a = 1
profile.run("main(a)")
This is because the variable 'a' will not properly be found. This function
fixes the problem.
"""
import profile
def run(statement, filename=None):
""" Runs 'statement' under profiler, optionally saving results in
'filename'.
This function takes a single argument that can be passed to the
"exec" statement, and an optional file name. In all cases this
routine attempts to "exec" its first argument and gather profiling
statistics from the execution. If no file name is present, then this
function automatically prints a simple profiling report, sorted by the
standard name string (file/line/function-name) that is presented in
each line.
