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.
pip install evdspy
from evdspy import *
check()
get()
help_evds()
or
import evdspy as ev
ev.check()
ev.get()
ev.help_evds()
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.
create_series_file()
or
csf()
or from selection menu choose create series file (config_series.cfg) option.
With this command program will create file similar to below. You may later add new series info or modify this file or delete and create a new on from menu or console using commands summarized in this file.

creates folders and files
____Folders_______________
`pickles`
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 *
setup_now()
# 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
get()
Program will store your api key in your environment in a safe folder
called APIKEY_FOLDER
and only use it when you run a new request which was not requested
recently depending on your cache preference.
.
save("MyApiKey")
When you call it without any argument, program will ask for your key and do the same
