I need to open an ArcGIS Pro project (.aprx) file in the ArcGIS Pro application inside of an arcpy script.

Does anyone know of a way to accomplish this?

I am using ArcGIS pro 2.4.1.

By open, I mean having the application actually open up on my screen. Similar to opening it from the start menu but utilizing the script instead.

I have done something similar to open PDF files in Adobe Acrobat Reader in the past so I just looked up this answer to Opening PDF generated by Python AddIn using Report (*.rlf) file automatcally? and tested:

import os
myfile = r"C:\Temp\Projects\TestProject\TestProject.aprx"
os.system("start " + myfile)

and it worked.


You can use:

aprx = arcpy.mp.ArcGISProject(r"C:\path\to\project.aprx")

For further things you can do with aprx refer to the documentation.

  • I meant open as in have it pop up, as if the icon was double clicked. Let me update the question.

you can also use subprocess to do this. In my implementation, subprocess was a better choice.

import subprocess
myfile = r"C:\Temp\Projects\TestProject\TestProject.aprx"
subprocess.Popen([myfile], shell=True)
