The key concept here is transformation which can include but is not limited to:

The Python Map Function is a function that allows you to transform an entire iterable using another function. Iterables are objects that contain one or more members.

If any of this resonates with you, then you've come to the right place.īefore we move forward you need to understand what functions and iterables are:įunctions are code that performs a specific task. You want to impress your peers with your robust coding knowledge. Picture this: you want to become a more efficient coder.

If you're learning how to code, the Python Map Function is your opportunity to level up. update_layout ( mapbox_style = 'white-bg', mapbox_layers = [ ) fig. scatter_mapbox ( us_cities, lat = 'lat', lon = 'lon', hover_name = 'City', hover_data =, color_discrete_sequence =, zoom = 3, height = 300 ) fig. read_csv ( '' ) import plotly.express as px fig = px. Here is a simple map rendered with OpenStreetMaps tiles, without needing a Mapbox Access Token:

A Mapbox service style URL, which requires a Mapbox Access Token or an on-premise Mapbox installation.

'basic', 'streets', 'outdoors', 'light', 'dark', 'satellite', or 'satellite-streets' yield maps composed of vector tiles from the Mapbox service, and do require a Mapbox Access Token or an on-premise Mapbox installation.

'open-street-map', 'carto-positron', 'carto-darkmatter', 'stamen-terrain', 'stamen-toner' or 'stamen-watercolor' yield maps composed of raster tiles from various public tile servers which do not require signups or access tokens.

'white-bg' yields an empty white canvas which results in no external HTTP requests.

If your does not use data from the Mapbox service, you do not need to register for a Mapbox account. This token should be provided in _token (or, if using Plotly Express, via the px.set_mapbox_access_token() configuration function).

If your basemap in uses data from the Mapbox service, then you will need to register for a free account at and obtain a Mapbox Access token. The word 'mapbox' in the trace names and layout.mapbox refers to the Mapbox GL JS open-source library, which is integrated into Plotly.py. Mapbox Access Tokens and When You Need Them ¶ is an array that defines more layers that are by default rendered above the traces in data (although this can also be controlled via the below attribute).The various traces in data are by default rendered above the base map (although this can be controlled via the below attribute).defines is the lowest layers, also known as your 'base map'.Mapbox tile maps are composed of various layers, of three different types: This page documents Mapbox tile-based maps, and the Geo map documentation describes how to configure outline-based maps. If your figure is created with a px.scatter_geo, px.line_geo or px.choropleth function or otherwise contains one or more traces of type go.Scattergeo or go.Choropleth, the layout.geo object in your figure contains configuration information for the map itself. If your figure is created with a px.scatter_mapbox, px.line_mapbox, px.choropleth_mapbox or px.density_mapbox function or otherwise contains one or more traces of type go.Scattermapbox, go.Choroplethmapbox or go.Densitymapbox, the layout.mapbox object in your figure contains configuration information for the map itself. Plotly supports two different kinds of maps:
