Praat Acoustic Analysis Automation

All of my wav files are already trimmed, labelled, and sitting inside Praat TextGrid folders—session 1 (pre-training), session 2 (post-training) and session 3 (dedicated voice work). I have a Praat script will open each file, extract pitch, formants and intensity measurements, and then generate a clear comparison across the three sessions which needs to be run.

Here is what matters:
• For every file it should save a tidy, comma-separated table that contains at least the mean, median and standard-deviation for the acoustic features.
• After extraction, I want a analysis that explores the differences between sessions
