Introduction

I've written this module to learn python and some python basics like using unittests, imports and how python modules/packets work.

This module is inspired by the linux bash command.

At the moment this module provides four functions, which can be used to manipulate strings. For further information see here: How to use

The cli interface for this module is now available.

Getting started

Prerequisites

• Python installed
• Operatingsystem: Linux or Windows, not tested on mac
• IDE like VS Code, if you want to contribute or change the code

Installation

There are two ways to install this module depending on the way you work and the preinstalled modules:

1. pip install pycutroh
2. python -m pip install pycutroh

How to use

How to Import

You can import the module in two ways:

import pycutroh

• This will import all functions. Even the ones that are not supposed to be used (helper functions).

from pycutroh import *

• This will import only the significant functions, meant for using.

Using the module

Depending on the way you imported the module, the following examples look a bit different.

Example 1:

from pycutroh import *

print(get_letter_on_pos("This is a demonstration string.",0))

Result:

T

Example 2:

from pycutroh import *

print(get_letters_from_pos_to_pos("This is a demonstration string.",(0,4)))

Result:

This

Example 3:

from pycutroh import *

print(get_fields("This is a demonstration string.",(0,3)," "))

Result:

This demonstration

Example 4:

import pycutroh

print(pycutroh.get_fields_new_separator("This is a demonstration string.",(0,3)," ","|"))

Result:

This|demonstration

Using the cli

You can now use the cli of the pycutroh module. This cli is my first using the argparse module, so there might be adjustments in the future.

To show the help run the following command:

python -m pycutroh -h

Result:

usage: __main__.py [-h] [-s STRING] [-glop GETLETTERONPOS | -glbp GETLETTERSFROMPOSTOPOS GETLETTERSFROMPOSTOPOS] {f} ...

positional arguments:
  {f}                   Get fields separated by specified delimiter.
    f                   Get fields by delimiter and join using same delimiter.

options:
  -h, --help            show this help message and exit
  -s STRING, --string STRING
  -glop GETLETTERONPOS, --getLetterOnPos GETLETTERONPOS
                        Letter on position to return.
  -glbp GETLETTERSFROMPOSTOPOS GETLETTERSFROMPOSTOPOS, --getLettersFromPosToPos GETLETTERSFROMPOSTOPOS GETLETTERSFROMPOSTOPOS
                        Get letter between positions.

Using a function:

python -m pycutroh f --getFields (0,1,2,3) --delimiter " " --newDelimiter ","

Result:
