Project description

measure / limit the function execution time, cross-platform
Install
pip install timework
Usage
import timework as tw
timework.timer
A decorator measuring the execution time.
timework.TimeError
contains three parts:
TimeError.message
string, <decorated function name>: <time used> seconds usedTimeError.result
return values of the function being decoratedTimeError.detail
float, time used
Notice: In @timer
decorator, timeout
is used to raise a Error
after the decorated function finishes, but fails to finish within timeout
seconds. If you want to terminate the function with a timeout
limit, please use @limit
.
