bpo-29862: Fixed grammar error in TypeError exception message in reload function

[mandeep]

Fixed the grammar error found by Brett in the TypeError exception message on Line 140. All tests passed after making the change so I went ahead and created this pull request. If I need to add a test that checks the exception message, please let me know.

Looks good :) Thanks, @mandeep 🎉

[Mariatta]

@mandeep Could you add a test for this change? Thanks :)

[orsenthil]

@Mariatta , we only assert the Exception Type, and we don't test the contents of the Exception Str. So, the change LGTM as it is.

[Mariatta]

Ah ok, Thanks @orsenthil :) I thought we needed to get codecov green by adding test. In that case I can merge this. Still wondering whether this needs to be backported at all?

[orsenthil]

Since it is a grammar / spell fix, backporting seems harmless to me. +1 if you were planning to do that.

[mandeep]

@Mariatta sorry I couldn't respond sooner. Thanks for submitting the backport changes. 😃

[Mariatta]

Thanks again @orsenthil and @mandeep :)
This has been backported into 3.5 and 3.6, and I closed the b.p.o issue. 🎉
