Creating a shape file from a bounding box coordinates list

Question

There is already few existing questions about this topic, but I unfortunately did not find something that could fix my problem.

I have a point Lat, Long coordinate i.e. Lat= 10 and Long = 10. I want to create a shape file of a 0.5 degree bounding box around this point, so the bounding box should be as follow:

1. minimum Long= 9.75
2. minimum Lat = 9.75
3. maximum Long = 10.25
4. maximum Lat = 10.25

Does anyone knows how to do that in Python?

Here's one way to do it using shapely, geopandas and pandas:

import geopandas as gpd
import pandas as pd
from shapely.geometry import Polygon


def bbox(lat,lng, margin):                                                                                                                  
    return Polygon([[lng-margin, lat-margin],[lng-margin, lat+margin],
    [lng+margin,lat+margin],[lng+margin,lat-margin]])

gpd.GeoDataFrame(pd.DataFrame(['p1'], columns = ['geom']),
     crs = {'init':'epsg:4326'},
     geometry = [bbox(10,10, 0.25)]).to_file('poly.shp')
