Code with global variables

[Peter__B]

Hi

The following code has been written just for my own education and understandig and does not generate anything of value.

However, does anybody know why the code does not print 'newstring' to the spyder console window ? Instead it prints 'string', what commands do I have to add to the code in order get the 'newstring' to the console window. I have tried with global variables without success.

Best Regards

Peter

Sorry I forgot the code:

import adsk.core, adsk.fusion, adsk.cam, traceback

text='string'

def run(context):

ui = None

try:

app = adsk.core.Application.get()

ui = app.userInterface

# ui.messageBox('Hello script')

product = app.activeProduct

design = adsk.fusion.Design.cast(product)

global trt

text='newstring'

rootComp = design.rootComponent

sketches = rootComp.sketches

xyPlane = rootComp.xYConstructionPlane

sketch = sketches.add(xyPlane)

sketch.name = 'FirstComponent'

xzPlane = rootComp.xZConstructionPlane

sketch = sketches.add(xzPlane)

sketch.name = 'SecondComponent'

exportMgr = design.exportManager

fusionExportOptions = exportMgr.\

createFusionArchiveExportOptions('D:/FusionData/CadTest')

exportMgr.execute(fusionExportOptions)

return text

except:

if ui:

ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

print(text)

The error is due to the nature of python. Your print statement is outside the body of the run method. When python loads a source file it executes it. When the file is executed the text='string' code is evaluated, the "def" statement is evaluated and the "run" method is created (in python methods ARE objects too!), then your print(text) statement is executed, and the execution of the file completes (without ever executing the contents of the run method. Then some time later the python layer inside Fusion looks for and finds a method with the name of "run" and executes it.

So the problem is the contents of your run method are NOT executed before your print statement. I hope this helps - if not the internet can do a better job of explaining things than I have I'm sure.
