CLN: F-string formatting in pandas/tests/indexes/*.py (#29547)

[yashukla]

• closes #xxxx
• tests added / passed
• passes black pandas
• passes git diff upstream/master -u -- "*.py" | flake8 --diff
• whatsnew entry

I'm a little unsure how to interpret the results of the checks - since code_checks.sh exits with an error at a line where isort is called, it seems like it would point to an issue with importing. However, I haven't changed any import statements, and I checked that all the pytests were consistent with before I changed anything, so I'm not sure what the issue is.

Hi @yashukla the issue is related to black opposed to isort see:

black, version 19.3b0
Checking black formatting
would reformat /home/vsts/work/1/s/pandas/tests/indexes/test_common.py

can you run black pandas on the changes?

Also please could you reference the issue:

#29547

thanks!

@alimcmaster1 Oh, I wasn't using black correctly. Thanks so much! Correct issue referenced, formatting fixed, and code now passes black pandas and git diff upstream/master -u -- "*.py" | flake8 --diff, along with checks; anything else that needs to be done?
