# LitPerf

Lightweight performance tracker for Python code - zero overhead when disabled.

# install

```bash

pip install git+https://github.com/Lightning-AI/litperf.git

```

# Example use

```python

from litperf import PerfTimer

timer = PerfTimer()

    

# Step 1

numbers = [i * i for i in range(50000)]

timer.mark("step1: count")

# Step 2

total = 0

for num in numbers:

    total += num / 2

timer.mark("step2: sum_numbers")

timer.print_report()

```

The above generates the following report:
