Cereja 🍒

Cereja is a bundle of useful functions that I don't want to rewrite.

How many times have you needed to rewrite that function or base class? Well, I thought then of joining all my lines of code, bit by bit, in one place.

Not well structured yet :( ... But you can help me !!!

Getting Started DEV

Don't be shy \0/ ... Clone the repository and submit a function or module you made or use some function you liked.

See CONTRIBUTING 💻

Setup

• Python 3.6+
• Pip3

Installing

Install Cereja Package

python3 -m pip install --user cereja

or for all users

python3 -m pip install cereja

Note: If you're using Windows, you don't need use python3, but make sure your python path settings are correct.

Cereja Example usage

See some of the Cereja tools

Filetools

Have a fun

from cereja import FileIO
# load File
file = FileIO.load('test.json') # return FileIO.json object (has interface for .txt, .csv, .json and more)
print(dir(file))

Corpus

Great training and test separator.

Create from list data

import cereja as cj

X = ['how are you?', 'my name is Joab', 'I like coffee', 'how are you joab?', 'how', 'we are the world']
Y = ['como você está?', 'meu nome é Joab', 'Eu gosto de café', 'Como você está joab?', 'como', 'Nós somos o mundo']

corpus = cj.Corpus(source_data=X, target_data=Y, source_name='en', target_name='pt')
print(corpus) # Corpus(examples: 6 - source_vocab_size: 13 - target_vocab_size:15)
print(corpus.source) # LanguageData(examples: 6 - vocab_size: 13)
print(corpus.target) # LanguageData(examples: 6 - vocab_size: 15)

corpus.source.phrases_freq
# Counter({'how are you': 1, 'my name is joab': 1, 'i like coffee': 1, 'how are you joab': 1, 'how': 1, 'we are the world': 1})

corpus.source.word_freq
# Counter({'how': 3, 'are': 3, 'you': 2, 'joab': 2, 'my': 1, 'name': 1, 'is': 1, 'i': 1, 'like': 1, 'coffee': 1, 'we': 1, 'the': 1, 'world': 1})

corpus.target.phrases_freq
# Counter({'como você está': 1, 'meu nome é joab': 1, 'eu gosto de café': 1, 'como você está joab': 1, 'como': 1, 'nós somos o mundo': 1})

corpus.target.words_freq
# Counter({'como': 3, 'você': 2, 'está': 2, 'joab': 2, 'meu': 1, 'nome': 1, 'é': 1, 'eu': 1, 'gosto': 1, 'de': 1, 'café': 1, 'nós': 1, 'somos': 1, 'o': 1, 'mundo': 1})

# split_data function guarantees test data without data identical to training
# and only with vocabulary that exists in training
train, test = corpus.split_data() # default percent of training is 80%

Read from .csv

import cereja as cj

corpus = cj.Corpus.load_corpus_from_csv('path_to_file.csv', src_col_name='x_data', trg_col_name='y_data', source_name='en', target_name='pt')
# now you have a Corpus instance, have fun! (:

Progress

import cereja as cj
import time

def process_data(i: int):
    # simulates some processing 
    time.sleep(cj.rand_n()/max(abs(i), 1))

my_iterable = range(1, 500)
my_progress = cj.Progress("My Progress")

for i in my_progress(my_iterable):
    process_data(i)

Custom Display

import cereja as cj
import time

progress = cj.Progress("My Progress")
print(progress)

print(progress[0])
print(progress[1])
print(progress[2])

class MyCustomState(cj.StateBase):
    def display(self, current_value, max_value, *args, **kwargs):
        return f'{current_value} -> {max_value}'
    def done(self, *args, **kwargs):
        return f'FINISHED'

progress[0] = MyCustomState

for i in progress(range(1, 500)):
    time.sleep(1/i)

With Statement

import cereja as cj
import time

with cj.Progress("My Progress") as prog:
    time.sleep(5)
    for i in prog(range(1, 500)):
        time.sleep(1/i)
