New submission from A A <[email protected]>:
Idle3 with python 3.7.3 on Debian Buster and XFCE.
Attempting to run the line 'print ("Hello World" * 8**8)' from either the Idle
shell window or Idle editor will cause Idle to hang and one CPU core runs
100%.(allowed it to run for several minutes)
ctl+c or menu Shell>interrupt execution simply pauses CPU processing but does
not terminate the process nor is there an option to continue the process.
Following this interrupt with use of menu Shell>Restart-shell causes Idle to
fully freeze and then requires a system terminate signal to close Idle.
The same line of python used in Idle on another student's MS-Windows laptop
required ctl-alt-del this was a fresh download with v3.9 as I recall.
When used used on the system Bash shell and python 3.7.3, the line operates
without any trouble and finishes in 20seconds as: $ python3 -c 'print ( "Hello
World " * 8**8)'
Suggestion is that the ctl+c or the Interrupt menu option in Idle should
terminate the running code rather than pause it.
