Minor detail, but looks good to me, improves consistency. Thanks!

@jgbarah Yeah, i was trying to run CoCom & CoLic backends so found these. thought these would help others who might refer Readme.md for starters 😄

Thank you @inishchith for the PR. Overall LGTM, I would ask you to:

• if possible squash the commits in one.
• prepend each commit message with a label, for instance [doc] Fix documentation for Cocom backend.
• include some lines in the commit message to describe its content. For instance, you could reuse the PR description (without adding the references).

@valeriocos Thanks for the review. I've reset and made them into a single commit and updated the commit message as required. Let me know if any changes required 😅

[valeriocos]

Thank you for the quick reply @inishchith , just a minor thing about the commit message.
The one below is the current one:

* [doc] Fix documentation for Cocom backend

    Fix python interface example of `CoCom` backend under documentation.
* [doc] Fix parameter definition.

please change it to:

[doc] Fix documentation for Cocom backend

Fix python interface example of `CoCom` backend under documentation and parameter definition in `CoCom` class

[inishchith]

@valeriocos Sorry for that. I've updated the commit message.
