I spent my Ph.D. coding in MATLAB, as my Ph.D. was experimental and MATLAB was mainly used for data analysis and plotting. On the other hand, I had a full conda package with complete documentation up and running by the end of my postdoc. Though this was a side project, the time spent on this was incredibly valuable. I did not have to prove to anyone I was proficient in Python; my GitHub was enough. Additionally, the vast majority of researchers' extent of Python expertise was limited to disjointed Jupyter notebooks - while I had a running package with extensive documentation. I got 3 job offers just based on my package itself - while very few non-academic jobs were interested in my publications. The fact that I had a few first-authors in reputed journals was enough; nobody was interested in their contents.
