When finding a solution to a problem by exploratory programming in a REPL I find it very useful to use print statements to build a log and provide insights into application state and flow.

Unfortunately ArcMap's Python Console seems to go silent after calling some of the geoprocessing tools.

For example:

>>> print("test 1")
... arcpy.ExcelToTable_conversion(source_path, target_sheet, source_sheet)
... print("test 2")
test 1

While if I remove the call to the Excel To Table tool:

>>> print("test 1")
... pass
... print("test 2")
test 1
test 2

How can I reliably print to the console or otherwise work around this issue?

I am running:

  • ArcGIS Desktop

I have read the following QAs on print or messaging in ArcPy but haven't found one that matches the use case of using the Python Console:

  • @MichaelStimson From the console? Mar 6 '18 at 3:38

    Have you tested this with another geoprocessing tool? I recall having issues with Excel to Table tools in 10.3.1. Is the tool failing?

  • @ Fezter Excell To Table is completing without error and producing the correct data. However Get Count is not producing this behavior. Mar 6 '18 at 4:54

There is something odd about the prompt of "..." that you get after your first print statement.

When I type print("test1") and use the Enter key I get a prompt of ">>>":

>>> print("test1")

I am using ArcGIS Desktop 10.6 but I will be surprised if this has changed since 10.3.

As a second test I typed these lines of code into IDLE, and then copied them to my paste buffer using Ctrl-V:


I pasted them into the Python window, followed by the Enter key twice and got the output below. I think this is the expected behaviour.

>>> print("test1")
... arcpy.GetCount_management(r"C:\Temp\test.gdb\TestFC2")
... print("test2")
  • The three lines have been pasted as a unit. Mar 6 '18 at 3:48
  • What were your precise steps to do that?

  • Type in an external text editor (notepad++) then ctrl-c, ctrl-v. Mar 6 '18 at 3:53
  • Try pasting each line in individually...I've seen similar behaviour when trying to paste a block of code into the Python console.

  • OK, print is working after GetCount but still silent after ExcelToTable. It looks like only some tools have this issue. Mar 6 '18 at 4:55
