python tools/test.py -J --mode=release parallel/test-*

[ronag]

python tools/test.py -J --mode=release parallel/test-* doesn't seem to work anymore?

node$ python tools/test.py -J --mode=release parallel/test-*
  File "tools/test.py", line 230
    print(f" failed {len([i for i in outputs if i.UnexpectedOutput()]) + 1} out of {self.measure_flakiness + 1}")

I had to upgrade my python version for it to work properly.
What version are you using?

[ronag]

2.7

I think #43954 made tools/test.py work only on python 3
@ronag can you confirm by running python3 tools/test.py -J --mode=release parallel/test-*?

NVM, I reproduced locally:

python2 --version
Python 2.7.18

python2 tools/test.py -J message
  File "tools/test.py", line 230
    print(f" failed {len([i for i in outputs if i.UnexpectedOutput()]) + 1} out of {self.measure_flakiness + 1}")
                                                                                                               ^
SyntaxError: invalid syntax

and

python --version
Python 3.9.13

python tools/test.py -J message
[00:07|% 100|+  66|-   0]: Done

I am not sure how important it is to support python 2

[ronag]

Thanks! That fixed it.

We dropped support for Python 2 some time ago. It has been EOL for a while. @nodejs/python might have more context to supply (especially @cclauss).

Python 2 died 963 days ago on 1/1/2020. No security updates since then -- It should no longer be trusted.
