api_key usage with evdspy python package

api key will be read from .env file on load if available.  

.env file [Alternative 1]

You may create a .env file in your work environment and write your api key as follows. Script will load your api key from this file on load if available.

    # filename : `.env`  
    EVDS_API_KEY=AxByCzDsFoGmHeIgJaKrLbMaNgOe

Proxy from .env file

You may also define your proxies as below in your .env file. Script will load your proxies from this file if they exist.

# example `.env`  file content 

EVDS_API_KEY=AxByCzDsFoGmHeIgJaKrLbMaNgOe
http_proxy=http://proxy.example.com:80
https_proxy=http://proxy.example.com:80

Visual Menu to request data

About

evdspy is an open source python interface which helps you make efficient requests by caching results (storing a dict using hashable parameters in order to avoid redundant requests), it provides a user friendly menu to ask data from the institution's API service. It is a Python interface to make requests from (CBRT) EVDS API Server. Fast, efficient and user friendly solution. Caches results to avoid redundant requests. Creates excel files reading configuration text file that can be easily created from the menu or console. Provides visual menu to the user. It is extendable and importable for user's own python projects.

menu

from evdspy import *
menu()

or import evdspy as ev ev.menu() Menu function will display a friendly menu to setup project, creating output folders and some setup files to create some set of series to make a request and download from EVDS server save your api key to get data from EVDS. Than it will convert this data to a pandas dataframe and create some folders on your local area.

setup() :

creates folders and files
____Folders_______________
        `caches`
            will be used to store some request results to ovoid redundant requests from the EVDS api
        `SeriesData`
            to save results of requests or caches to an excel file using information on user option files
____Files_______________
        `options.cfg`
            a text file consisting global user options such as start date, end date and caching period.
        `config_series.cfg`
            this file consists information regarding individual sets of series. From the menu user can add
        new series that will be requesting from the server. Program will produce on for example and this file
        can be modified and new sets of series can be added following the example format.
from evdspy.main import *

get():

# this will check for your current series.txt file
# if proper data series codes are given it will either download them
# or use the latest cache from your local environment
# to provide other cache options such as nocache / daily / hourly you may change your
# defaults or give arguments such as
