get_bonds
(country=None)ΒΆ This function retrieves all the bonds data stored in bonds.csv file, which previously was retrieved from Investing.com.

- Parameters
country (
str
, optional) β name of the country to retrieve all its available bonds from.- Returns
The resulting
pandas.DataFrame
contains all the bond data from the introduced country if specified, or from every country if None was specified, as indexed in Investing.com from the information previously retrieved by investpy and stored on a csv file.So on, the resulting

get_bonds_dict
(country=None, columns=None, as_json=False)ΒΆ This function retrieves all the bonds information stored in the bonds.csv file and formats it as a Python dictionary which contains the same information as the file, but every row is a
dict
and all of them are contained in alist
. Note that the dictionary structure is the same one as the JSON structure. Some optional paramaters can be specified such as the country, columns or as_json, which are a filtering by country so not to return all the bonds but just the ones from the introduced country, the column names that want to be retrieved in case of needing just some columns to avoid unnecessary information load, and whether the information wants to be returned as a JSON object or as a dictionary; respectively.- Parameters
