Good morning. I m trying without success to find where I can learn all the functions that are in the helper window in the field calculator. Be it a tutorial, manual or index explaining what does each function. Thanks in advance.
Most of those are python related, like the string methods and builtin types.
There is definitive descriptions here, but some may find the explanations too concise, hence any general programming book or one directed towards python would help. The terminology is common to many programming languages.
