I wanted to learn R and Python for genomics work and i have experience in using GUI platforms like Galaxy and CLC for NGS analysis. I am now looking to expand my knowledge in coding based NGS analysis and looking for online courses to learn.
Agreeing with Abhijeet, I may suggest you to look for "Cookbooks" for the specific objectives you are trying to solve. As the name says, it's more like a recipe, where you can read workflows that will guide you through every step. (Other tip may be googling for "subject/software tutorial".
Based on personal experience I can suggest to just "learning by doing" approach. If you don't have your won data set or real aim about what you want to do, it will take longer to learn.
And there are already ready made pipelines available for most of the things. Just follow the user-manual of related tool.

You can learn easily from Coursera and Edx. These platforms are for free. But, you if want a credential you have to pay. Also, you can apply for a financial aid in Coursera. Best wishes!
