Python - Data structures

[curd_rice]

Hi friends ,

Currently my background is in ETL , no experience of any programming lang like Java , C++ , Python , etc .

I am from EEE background in Btech and Masters . 
It’s been about 12 yrs I have been doing ETL , working on different ETL tools but not an expert in any . 
My question is , if I have to learn programming like python along with data structures. How difficult will it be for the transition and for me understand and learn . 
Please provide your inputs and any references or sites to get started on the leaning path courses .
