[New-bugs-announce] [issue44284] Python references wrong line but correct line number in traceback

[helpimnotdrowning]

New submission from helpimnotdrowning <helpimnotdrowning at gmail.com>:

To reproduce (at least on Windows 10 w/ Python 3.9.4):

1) Make a python file:

while True:
    print('hello')

2) Run the file via cmd
3) Edit the file (while it is still running):

while True:
    print('goodbye')
    print('hello')

then save it
4) ctrl+c in the cmd window to exit the script
5) The traceback will look something like this:

Traceback (most recent call last):
  File "dfbssss.py", line 2, in <module>
    print('goodbye')
KeyboardInterrupt

The traceback mentions the print('goodbye') even though it wasnt in the file when it was run. It still calls it line 2, which is the line the print('hello') was before adding the print('goodbye')
