✨ Extend your string powers with Str+

Setup [Optional]¶

Create a virtualenv 🔧

Create a new virtualenv before start this notebook to be able to select it as the kernel, if you want!

• Create a new virtualenv.

  pyenv virtualenv 3.9.16 .envStrPlus
  pyenv activate .envStrPlus
  pip install --upgrade pip
  pip install ipykernel
  

• Delete the virtualenv.

  pyenv deactivate .envStrPlus
  pyenv virtualenv-delete -f .envStrPlus
  

• Should return empty

  pyenv versions | grep .envStrPlus
  

Required! 💢¶

In [ ]:

pip install --upgrade strplus

pip install --upgrade strplus

In [3]:

from strplus import Str

from strplus import Str

😍 Simples use no parentheses!¶

In [4]:

my_string = Str("Cast_this_string_TO_Pascal!")

my_string.pascal

my_string = Str("Cast_this_string_TO_Pascal!") my_string.pascal

Out[4]:

'CastThisStringToPascal'

In [5]:

my_string = Str("cast_this_string_to_camel")

my_string.camel

my_string = Str("cast_this_string_to_camel") my_string.camel

Out[5]:

'castThisStringToCamel'

In [6]:

my_string = Str("Cast_this_StringToSnake")

my_string.snake

my_string = Str("Cast_this_StringToSnake") my_string.snake

Out[6]:

'cast_this_string_to_snake'

🔥 You can use with parentheses also!¶

Snake examples 🐍¶

In [7]:

Str("CastMeUseLikeANormalFunction").to_snake()

Str("CastMeUseLikeANormalFunction").to_snake()

Out[7]:

'cast_me_use_like_a_normal_function'

In [8]:

Str("CastThisPath/2021/01/01").to_snake()

Str("CastThisPath/2021/01/01").to_snake()

Out[8]:

'cast_this_path_2021_01_01'

Pascal examples 🐫¶

In [9]:

Str("cast_this_path_to_pascal/2021/01/01").to_pascal()

Str("cast_this_path_to_pascal/2021/01/01").to_pascal()

Out[9]:

'CastThisPathToPascal20210101'

In [10]:

Str("cat me to_Pascal Please").to_pascal()

Str("cat me to_Pascal Please").to_pascal()

Out[10]:

'CatMeToPascalPlease'

Camel 🐪¶

In [11]:

my_string.to_camel()

my_string.to_camel()

Out[11]:

'castThisStringToSnake'

In [12]:

Str("reference dataset").to_camel()

Str("reference dataset").to_camel()

Out[12]:

'referenceDataset'

Complex 👽¶

In [13]:

# Complex return, recursive Str
Str("MyStringWorks").to_snake().split("_")[0].pascal

# Complex return, recursive Str Str("MyStringWorks").to_snake().split("_")[0].pascal

Out[13]:

'My'

Common behavior 👌

"_".join returns a str class not a not or Str with the good features! In the Str we only have recessivity we are not overwriting the str from the global to Str, so it's normal and expected that behavior

In [14]:

try:
    "_".join(Str("MyStringWorks").to_snake().split("_")[0:1]).pascal
except Exception as e:
    print(e)

try: "_".join(Str("MyStringWorks").to_snake().split("_")[0:1]).pascal except Exception as e: print(e)

'str' object has no attribute 'pascal'

In [15]:

# you always has the built-in native Python functions
my_string.upper()

# you always has the built-in native Python functions my_string.upper()

Out[15]:

'CAST_THIS_STRINGTOSNAKE'

😏 Just use a specif function if you prefer!¶

In [16]:

from strplus.functions import *

from strplus.functions import *

In [17]:

to_camel("parse_to_camel")

to_camel("parse_to_camel")

Out[17]:

'parseToCamel'

In [18]:

to_snake("ThisIsAnotherTest")

to_snake("ThisIsAnotherTest")

Out[18]:

'this_is_another_test'
