Quick Start

Programmatic Usage

Using the WEO Wrapper

This example demonstrates how to use the WEO wrapper class to download, push to a database, and save WEO data:

from world_economic_outlook import WEO

weo = WEO()
weo.download("2025 April")  # Download the data for the specified vintage
weo.push("database.db", "weo")  # Push the data to a SQLite database table
weo.save("weo.xls")  # Save the data as an .xls file

Using the download Function

This example demonstrates how to use the download function to download WEO data and either save it to a file, push it to a database, or both in a single call:

from world_economic_outlook import download

download("2025 April", save_path="weo.xls", database="database.db", table="weo")

• vintage: The vintage string (e.g., '2025 April').
• save_path: (Optional) Path to save the WEO data as a file.
• database and table: (Optional) Push the data to a SQLite database.

Command-Line Interface (CLI)

The CLI provides a convenient way to interact with the WEO Downloader and is installed with the package.

Download and Save Data

This example downloads WEO data for a specific vintage and saves it as an .xls file:

weo download "2025 April" -save "2025_April.xls"

Push Data to a Database

This example downloads WEO data and pushes it directly to a SQLite database table:

weo download "2025 April" -database "database.db" -table "weo"

Perform All Actions

This example downloads WEO data, saves it as an .xls file, and pushes it to a database in one command:

weo download "2025 April" -database "database.db" -table "weo" -save "2025_April.xls"

Help

For more details, run:

weo --help

Useful Tools

simple-sqlite3

The simple-sqlite3 library is used in this project to interact with SQLite databases. Make sure you have already created the database and table by running the weo CLI to download the data:

weo download "2025 April" -database "database.db" -table "weo"

Below are some useful commands for exporting data from your SQLite database to different file formats such as CSV and JSON.

Export to CSV

db export -database "database.db" -table "weo" -format "csv" -output "weo.csv"

Export to JSON

db export -database "database.db" -table "weo" -format "json" -output "weo.json"

Fetching Data

This example shows how to fetch all database records for Brazil.

from simple_sqlite3 import Database

db = Database("database.db")

table = db.table("weo")

sql = """SELECT * WHERE iso = 'BRA'"""

results = table.query(sql)

print(results)

Example Output (from print(results)):

[   ...
    {
        "units": "National currency",
        "estimate": 0,
        "scale": "Billions",
        "weo_subject_code": "NGDP_R",
        "value": "522.938",
        "iso": "BRA",
        "subject_descriptor": "Gross domestic product, constant prices",
        "country": "Brazil",
        "vintage": "2025 April",
        "estimates_start_after": 2024,
        "year": 1980
    },
    {
        "units": "National currency",
        "estimate": 0,
        "scale": "Billions",
        "weo_subject_code": "NGDP_R",
        "value": "499.93",
        "iso": "BRA",
        "subject_descriptor": "Gross domestic product, constant prices",
        "country": "Brazil",
        "vintage": "2025 April",
        "estimates_start_after": 2024,
        "year": 1981
    },
    ...
]

More Fetch Conditions

This example shows how to fetch database records for Real GDP Growth for Brazil and Mexico in 2020 and 2021 from the 2025 April WEO.

from simple_sqlite3 import Database

db = Database("database.db")

table = db.table("weo")

sql = """ 
    SELECT year, value, country, weo_subject_code
    WHERE iso IN ('MEX', 'BRA')
    AND year BETWEEN 2020 AND 2021
    AND vintage='2025 April'
    AND weo_subject_code = 'NGDP_RPCH'
"""

results = table.query(sql)

print(results)

Example Output (from print(results)):

[
    {
        "year": 2020,
        "value": "-3.277",
        "country": "Brazil",
        "weo_subject_code": "NGDP_RPCH"
    },
    {
        "year": 2021,
        "value": "4.763",
        "country": "Brazil",
        "weo_subject_code": "NGDP_RPCH"
    },
    {
        "year": 2020,
        "value": "-8.354",
        "country": "Mexico",
        "weo_subject_code": "NGDP_RPCH"
    },
    {
        "year": 2021,
        "value": "6.048",
        "country": "Mexico",
        "weo_subject_code": "NGDP_RPCH"
    }
]
