After a while of fruitless attempt at automation I realised I was going to have to do this the much less satisfying way: a classic copy and paste job.

Manually, I scrolled my Medium stats page and copy and pasted into a .txt file. I then parsed that file into structured data using the following Python script.

import pandas as pdimport retext = open("medium_stats_raw.txt").read()pattern = re.compile( r"(.*?)\n([A-Za-z]{3,9} \d{1,2}, \d{4})\n([\d.,K]+)\nViews\n([\d.,K]+)\nReads\n(\$[\d.,]+|-)\nEarnings")def convert_k(val): return int(float(val.replace('K','')) * 1000) if 'K' in val… Read the full blog for free on Medium.
