Specifically, this code uses the csv, os, openai, langchain.embeddings.openai, langchain.chat_models, langchain.chains, langchain.vectorstores, and langchain.vectorstores.base modules. def read_csv_into_vector_document(file, text_cols): with open(file, new...
First we have the line number, which is used at the end to repeat the line of code infinitely. Most modern programming languages don’t have this idea of GOTO built in, because we’ve tried to abstract away from line numbers, and into more definite modules and functions with names....

And when it comes to reusing code in Python, it all starts and ends with the humblefunction. Take some lines of code, give them a name, and you’ve got a function (which can be reused). Take a collection of functions and package them as a file, and you’ve got amodule(which can...
Just as a proof-of-concept, here’s a barcode scanner written in six lines of Python code: import android droid = android.Android() code = droid.scanBarcode() isbn = int(code[‘result’][‘SCAN_RESULT’]) url = “http://books.google.com?q=%d” % isbn ...

1. Add fields to the attribute table for: a) straight line length; b) percentage slope; c) degrees slope. 2. Use the Field Calculator to compute the straight line length using this Python code. NB - if your polylines are straight, then you can omit this step and instead ca...
