whywhytools is a lightweight Python package for reading and writing JSON, JSON Lines (.jsonl), and Pickle files. It provides simple and intuitive APIs for handling these common data formats.

Installation

You can install this package using pip:

pip install whywhytools

Quickstart

JSON Lines (.jsonl)

Handle .jsonl files, supporting read, write, and append operations.

Write JSONL File

from whywhytools import write_jsonl

data = [
    {'id': 'data-1', 'text': 'hello world'},
    {'id': 'data-2', 'text': 'whywhytools is awesome'}
]

# Write to file
write_jsonl(data, 'output.jsonl') # [INFO] save to output.jsonl

# If file exists
write_jsonl(data, 'output.jsonl') # [INFO] output.jsonl already exists.

# Force overwrite existing file
write_jsonl(data, 'output.jsonl', force=True) # [INFO] save to output.jsonl

# Silent mode (not print any message)
write_jsonl(data, 'output.jsonl', force=True, silent=True)

Append to JSONL File

from whywhytools import append_jsonl

new_data = [{'id': 'data-3', 'text': 'new line'}]
append_jsonl(new_data, 'output.jsonl')

Read JSONL File

from whywhytools import read_jsonl

data = read_jsonl('output.jsonl')
print(data)
# [{'id': 'data-1', 'text': 'hello world'}, {'id': 'data-2', 'text': 'whywhytools is awesome'}, {'id': 'data-3', 'text': 'new line'}]

JSON (.json)

Handle standard .json files.

Write JSON File

from whywhytools import write_json

data = {'project': 'whywhytools', 'version': '0.1.0'}

# Write to file
write_json(data, 'config.json')

Read JSON File

from whywhytools import read_json

config = read_json('config.json')
print(config)

Pickle (.pkl)

Handle Python's pickle serialization format.

Save Pickle File

from whywhytools import save_pickle

model_data = {'weights': [0.1, 0.5, 0.9], 'bias': 0.01}
save_pickle(model_data, 'model.pkl')

Load Pickle File

from whywhytools import load_pickle

data = load_pickle('model.pkl')
print(data)

Plain Text (.txt or general text files)

Handle plain text files, supporting direct string reading or line-by-line list loading, as well as write and append operations.

Write Text File

from whywhytools import write_file

lines = [
    "First line of the text file.",
    "Second line is here."
]

# Write a list of strings to a file
write_file(lines, "document.txt")

# Write a single string
write_file("Just one line here.", "single_doc.txt")

Append to Text File

from whywhytools import append_file

# Append single or multiple lines
append_file("This is a newly appended line.", "document.txt")

Read Text File

from whywhytools import read_file

# Read entire file as a single string
content = read_file("document.txt")
print(content)

# Read file line by line into a list
lines = read_file("document.txt", lines=True)
print(lines)
