Got it, let's fix this issue where you're spawning a new tab for every location! The problem with your original approach is that the maps/place/ URL only targets one specific location at a time. Instead, we can use Google Maps' multi-location URL format to load all your markers in a single tab.

Step 1: Use Google Maps' Multi-Location Query Parameter #

Google Maps lets you pass multiple locations in a single URL using the q parameter, separating each location with a | character. This will display all locations as markers on the same map view.

Step 2: Control Tab Behavior with webbrowser.open #

To ensure the map opens in the same tab (instead of a new one every time), use the new=0 parameter in webbrowser.open(). This tells the browser to reuse an existing tab if it's available (note: this behavior can vary slightly between browsers, but it works reliably for most modern ones like Chrome or Firefox).

Full Code Example #

import webbrowser

# List of your target locations
locations = [
    "1235 N MULFORD RD ROCKFORD, IL",
    "100 State St, Rockford, IL",
    "500 E State St, Rockford, IL"
]

# Join locations with | to create a valid multi-location query string
combined_locations = "|".join(locations)

# Construct the Google Maps URL with all locations
map_url = f"https://www.google.com/maps?q={combined_locations}"

# Open the URL in the same tab (new=0)
webbrowser.open(map_url, new=0)

Bonus: Customizing Markers (Advanced) #

If you want more control over marker styles (like different colors or labels), you can create a custom map in Google My Maps:

• Open Google My Maps (you can find it via Google's search bar)
• Create a new map and add all your locations with custom markers
• Click "Share" and copy the "Link to view" URL
• Use that URL in webbrowser.open() instead of the dynamic query URL

This method gives you full customization over your markers, and everything loads in a single tab.
