Explode MultiPolygon geometry into individual Polygon geometries in a shapefile using GeoPandas and Shapely

	import geopands as gpd
	from shapely.geometry.polygon import Polygon
	from shapely.geometry.multipolygon import MultiPolygon

	def explode(indata):
	indf = gpd.GeoDataFrame.from_file(indata)
	outdf = gpd.GeoDataFrame(columns=indf.columns)
	for idx, row in indf.iterrows():
	if type(row.geometry) == Polygon:
	outdf = outdf.append(row,ignore_index=True)
