ArcMap can't find Python

RickCheney

My python scripts were running fine and then I upgraded from ArcGIS for Desktop - ArcMap 10.3 to 10.4.1

Now when I open a Python window and type >>> print "test" nothing happens

when I type >>> import os

>>> print os.sys.path

nothing happens. I think ArcMap is looking for Python in the wrong location. How can I fix this?

I have this folder on my Windows 7 computer: C:\Python27\ArcGIS10.4

It is best to uninstall other versions to upgrading. but none the less, bring up your favourite IDE and see what your path object is.

What is show is for 10.5... similar to 10.4 no less.

Here is the python requirements link , you can select 10.4 to see if there was anything different.

But in the end, the python27\\ArcGISxx.x version should match, but make sure there are no stray links in the sys path.

Thank you, I finally took your initial advice about uninstalling. I uninstalled and re-installed Python and then from the Windows Control Panel, Programs and Features, Uninstall or change a program, I selected ArcGIS 10.4.1 for Desktop and clicked Uninstall/Change which popped up a window which gave me the option to "Repair" the ArcGIS installation and now it is working perfectly.

I tried >>> print("hey") and >>>print ("hey") and still nothing. I tried to look up the commands for import sys using the ArcMap Python window but I didn't find anything different from what you showed me. Should I use parens around the commands in the ArcMap Python window?

DanPatterson_Retired

so you don't use your own python IDE? ok, here is arcmap's

Thanks Dan, I typed the following commands into the Python window in ArcMap. I hit the Return Key after each line. I typed each line from you answer, then I re-started the computer but, when I type >>> print "test" and press return, I don't get any response from the Python window. I assume I am missing a step?
