New submission from Marco Scataglini <[email protected]>:
Writing the following code in the IDLE module/scriptneditor and then running it
(F5) will momentarily freeze without giving the expected warning message
("SyntaxWarning: name 'GLOBAL1' is used prior to global declaration") and it
will crash all IDLE windows instances if ran multiple times after it.
------------------
start code snippet:
------------------
GLOBAL1=10
def test_chnge_val_1(a=1):
## global GLOBAL1
b=GLOBAL1
print GLOBAL1, b
global GLOBAL1
GLOBAL1 += a
b= 100
print GLOBAL1, b
if __name__ == '__main__':
test_chnge_val_1()
----------------
end code snippet:
----------------
The desired behavior is to not crash but run the code with output and shoot the
expected message to STOUT/shell console like regular python shell would.
