Presuming I am looking at the right link?: https://github.com/python/cpython/tree/main/Lib/test

I am currently focusing on Lambda function. I have a few test cases written. I have some questions too. Would be great if I could talk/chat to someone about these questions.

I am looking at: https://docs.python.org/3/reference/grammar.html

in which the following definition is found:

lambda_slash_no_default: | lambda_param_no_default+ '/' ',' | lambda_param_no_default+ '/' &':'

Can someone tell me how '/' is being used here in the syntax?

It just means the literal / character. It's the marker for positional-only parameters from PEP 570.

In addition, test_exceptions test a bunch of syntax errors and related locations. On Tue, 10 May 2022 at 06:41, Serhiy Storchaka wrote:

I'm wondering if there's a repository of test cases that test the Python grammar. Any help would be appreciated.

See test_grammar and test_syntax. And there are some test files for specific grammar features, like test_string_literals, test_unpack_ex, test_genexps, test_fstring, etc.
