Overview

The easydev package provides miscellaneous utility functions and classes that are repeatedly useful during the development of Python packages. The goal is to help developers speed up their work by providing ready-to-use tools for common tasks such as parameter validation, logging, progress bars, configuration files, multiprocessing, and more.

It has been used as an incubator for other packages (e.g., colormap) and is used in projects such as bioservices, sequana, and GDSCTools.

Installation

Install the latest release from PyPI:

pip install easydev

Features

• Parameter validation – check_param_in_list, check_range
• Dictionary utilities – swapdict, AttrDict (access dict keys as attributes, supports nested dicts)
• Logging – coloured logging via Logging class
• Progress bar – Progress works in Python, IPython, and Jupyter notebooks
• Timer – measure elapsed time with the Timer context manager
• Profiling – do_profile decorator using line_profiler
• Configuration files – CustomConfig and DynamicConfigParser for INI-style config management
• Shell commands – shellcmd and execute wrappers around subprocess/pexpect
• File utilities – touch, mkdirs, md5
• Multiprocessing – MultiProcessing class for easy parallel job execution
• Codecs – to_list, list2string and other conversion helpers
• URL utilities – isurl_reachable and related helpers
• Sphinx integration – bundled Sphinx theme and copybutton extension

Quick Start

Parameter validation:

from easydev import check_param_in_list, check_range

check_param_in_list("on", ["on", "off"])   # passes silently
check_range(0.5, 0, 1)                     # passes silently

AttrDict – access nested dictionary keys as attributes:

from easydev import AttrDict

d = AttrDict(**{"server": {"host": "localhost", "port": 8080}})
print(d.server.host)   # localhost
d.server.port = 9090

Coloured logging:

from easydev import Logging

logger = Logging("myapp", "WARNING")
logger.warning("something went wrong")
logger.debug("not shown at WARNING level")
logger.level = "DEBUG"
logger.debug("now it is shown")

Progress bar:

from easydev import Progress

pb = Progress(100)
for i in range(100):
    # do work here
    pb.animate(i + 1)

Timer:

from easydev import Timer
import time

times = []
with Timer(times):
    time.sleep(0.1)
print(f"elapsed: {times[0]:.2f}s")

Multiprocessing:

from easydev.multicore import MultiProcessing

def square(n):
    return n * n

t = MultiProcessing(maxcpu=4)
for i in range(10):
    t.add_job(square, i)
t.run()
print(t.results)
