uProfiler
Tools to help identify slow parts of your code.

profile
The profile decorator measures how long the function/method takes to execute.
If a name is not provided, then it is set to the decorated function name.
Decorated functions with the same name will overwrite each other's summary results.
The optional print_period will control how often the decorator will print
the call timings. Set to 0 to suppress all prints. The default global
print period can be configured via uprofiler.print_period.
Defaults to 1 (every call).
from time import sleep
import uprofiler
uprofiler.print_period = 1 # Modifies global default
@uprofiler.profile
def foo():
sleep(0.25)
@uprofiler.profile(name="changed_bar_name")
def bar():
sleep(0.6)
@uprofiler.profile(print_period=3)
def baz():
sleep(0.1)
foo()
bar()
bar()
baz()
baz()
baz()
print_results
Prints total execution time, as well as a summary of all profile calls.
Total-Time is computed as the elapsed time between initial uprofiler
import and the print_results function call.
Place this at the end of your script.
import uprofiler
uprofiler.print_results()
The printed output table in this case is empty, since no profile calls were made.
