The Python Performance Tuner

# PPT - The Python Performance Tuner

`ppt` is a tool for tuning the performance of Python programs.

## Install

~~~shell
pip install ppt
~~~

## Example

~~~python
import ppt
import time

if __name__ == '__main__':

for _ in range(10):

ppt.time('big')
time.sleep(0.5) # Big computation

ppt.time('medium')
time.sleep(0.3) # Medium computation

ppt.time('fast')
time.sleep(0.01) # Fast computation

# Stop current timing
ppt.stop()

# Print current timings
ppt.summary()

# Detailed statistics from pstats
ppt.stats()

~~~

**Output**

~~~
big: 40 function calls in 5.006 seconds
medium: 40 function calls in 3.003 seconds
fast: 40 function calls in 0.101 seconds
