tefas 1.0.0

Extract text from a YouTube video in a single command, using OpenAi's Whisper speech recognition model

tefas

Get daily price data of 5 years from TEFAS, Turkey's exchange traded funds (in Turkish: Yatırım Fonları) platform https://www.tefas.gov.tr

TEFAS doesn't provice an API for easy data retrieval, so the program uses Selenium to physically visit the website and scrape the data

Installation

pip install tefas

Usage

import tefas

data= tefas.get_data("AFT","MAC","TCD")

call tefas.get_data() function with ETF names. You can pass as many ETFs as you want. You will get a Pandas dataframe with days as indexes and each ETFs daily price as columns

You can pass an optional verbose=False argument if you want to disable printg progression to console

import tefas

data= tefas.get_data("AFT","MAC","TCD",verbose=False)

Example Dataframe

Additional Features ?

I initially though about adding various data manipulation functions to the library. But to keep the library lightweight, I think it is enough to retrieve the dataframe. Because once the dataframe is ready, users can easily process the data according to their needs. Examples

import tefas

data= tefas.get_data("AFT","MAC","TCD")

# print correlation matrix between ETFs
print(data.corr(),"\n")

#print total percentage return for each ETF
for column in data:
    print(f"{column} total return: {data[column].iloc[-1] / data[column].iloc[0] * 100 - 100:.2f} %")

Output
