Installation and example

To install czv, run:

pip install czv

Or use uv pip instead of pip.

Let's say we want to print the total number of rows in a 4x3 CSV file fruits.csv including the header row:

import czv

output = czv.row_count(file_path="fruits.csv", include_header_row=True)

print(output) # 4

Development

You'll need to have maturin and uv installed. Set up a local virtual environment in the czv-python folder by running:

uv venv

Make sure to activate the virtual environment (instructions should be provided in your terminal after running the previous command).

Once you've activated the virtual environment, install dependencies by running:

uv pip install -r requirements.txt

Build package in local environment

maturin develop --uv --release

Run tests

pytest
