Raspberry Pi controlled kiln (part 2)
In my previous post on making a raspberry pi controlled kiln I reached the point with a script running on my Raspberry PI to measure the temperature and manually switch on and off the kiln. On a first attempt I wasn't able to make the master repo

I need to make a fixed-width text file from a Pandas DataFrame.

I followed a suggestion to use to_string method. I built out my solution only to find it adds a space between the columns in the output. A fixed-width file means each column must be an exact number of characters. I literally can't make the file I need with to_string.

Making a fixed-width text file is a very easy task in SAS. Trying to do this with Pandas has been extremely frustrating.

Okay this is kind of absurd but I guess a learning experience. Merging lots of data in #Python using #PythonPandas and a couple hundred frames in, it slows to a crawl. 15+ min and I abort.

Instead do batch processing of a hundred files a piece, then merge the resulting Parquet files again. Less than five minutes.
