This is A foundamental package containing some basic self-designed functions and types for Project PyCTLib.

Project description

pyctlib

Introduction

Package pyctlib is the fundamental package for project PyCTLib, a powerful toolkit for python development. This package provides basic functions for fast python v3.6+ programming. It provides easy communication with the inputs and outputs for the operating systems. It provides quick try-catch function touch, useful types like vector, timing tools like timethis and scope as long as manipulation of file path, reading & writing of text/binary files and command line tools.

Installation

This package can be installed by pip install pyctlib or moving the source code to the directory of python libraries (the source code can be downloaded on github or PyPI).

pip install pyctlib

Basic Types

vector

vector is an improved implement of list for python. In addition to original function for list, it has the following advanced usage:

In [1]: from pyctlib.basictype import vector                                         

In [2]: a = vector([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])                                  

In [3]: a.map(lambda x: x * 2)                                                       
Out[3]: [2, 4, 6, 8, 10, 12, 14, 16, 18, 20]

In [4]: a.filter(lambda x: x % 2 == 0)                                               
Out[4]: [2, 4, 6, 8, 10]

In [5]: a.all(lambda x: x > 1)                                                       
Out[5]: False

In [6]: a.any(lambda x: x == 2)                                                      
Out[6]: True

In [7]: a[a > 7] = 7                                                                 

In [8]: a                                                                            
Out[8]: [1, 2, 3, 4, 5, 6, 7, 7, 7, 7]

In [9]: a.reduce(lambda x, y: x + y)                                                 
Out[9]: 49

In [10]: a.index(lambda x: x % 4 == 0)                                               
Out[10]: 3

File Management

Timing Tools

scope

>>> from pyctlib import scope, jump
>>> with scope("name1"):
...     print("timed1")
...
timed1
[name1 takes 0.000048s]
>>> with scope("name2"), jump:
...     print("timed2")
...
>>>

timethis

>>> from pyctlib import timethis
>>> @timethis
... def func(): print('timed')
... 
>>> func()
timed
[func takes 0.000050s]

Touch function

>>> from pyctlib import touch
>>> touch(lambda: 1/0, 'error')
'error'
>>> touch('a')
>>> a = 4
>>> touch('a')
4
