Using Python Print Statement in Dynamo


As of Dynamo 1.2, it’s still not possible to add additional OUT ports, but I did figure out a trick to redirect print( ) so you can “log” them.

It doesn’t actually stream it in the way a stdout typically would, but it does store all the data printed, and then you can assign the value to your OUT output.

In the absence of a debugger, I tend to add print statements all over the place when I am troubleshooting python , so I find this very helpful.

sys.stdout = output

t1 = time.time()

print('Starting Test')





duration = time.time() - t1

print('Finished in {} seconds'.format(duration))

OUT = output.getvalue()
