A bug fixed by correcting missing parentheses

[sum33it]

This PR fixes a bug in the code. The parenthesis were missing at couple of places.

This certainly fixes the bug, but couldn't we also just remove the ( right before dict_waveform_modification? Then we do not need the closing parentheses in lines 102, 246 (or the ones that are added, does not matter). And I do not see any reason why Python would want them there

@sum33it Please could you implement @MaxMelching 's suggestion here. Having additional, unnecessary extra parentheses impacts on code readability.

PyCBC aims to use black's (https://pypi.org/project/black/) formatting. If you remove the parentheses and reformat (this entire code) with black it would make things more readable.

Hi @spxiwh Thanks for pointing this out. I will do it in next PR.

[MaxMelching]

@spxiwh I like the black suggestion. Is there any specific config setup that PyCBC uses? Looking through the pyproject.toml and some other files, I couldn't find one, so I guess you are using the black defaults?

We just use the default settings ... Though having a properly defined config within the repository ... and actually running it on a bunch of older code would be good!

This is described here (https://github.com/gwastro/pycbc/wiki/How-to-satisfy-CodeClimate) ... I agree that this is not an ideal place for this to live!
