I have to confess that I’m not very knowledgeable about javascript etc., although I have dabbled with it occasionally. I was considering using XSLTProcessor.transformToFragment() . Is that the right approach? Can I use the load method you suggest to get access to a node reference to pass to the above?

I had considered the requests idea before, but the ox garage site has a javascript convert button. According to some comments on stackexchange, that can be awkward to deal with (can be handled with Selenium, but there are problems getting it working on ios - needs a browser driver).

Cheers!

Does import os ; print(os.system("/bin/ls")) do anything?

https://docs.python.org/3/library/os.html#os.system

import os ; print(os.system("/bin/bash")) would be a superpower if it actually worked!

https://docs.python.org/3/library/runpy.html is used by Pyto a lot but that is for launching Python scripts, not system binaries.

@mikael Hope I'm reading this right.

@JonB said:

data=read(f)

Shouldn't it be f.read()?

I have to find all the numerical values in that text file and compute their sum. How can I do this in Pythonista?

Assuming each line has exactly one numerical value:

def read_ints_from_file(p): """ Read integers from file path p. """ values = [] # open file read-only with open(p, "r") as fin: # read file line by line for line in fin: # remove any leading/trailing whitespace characters and convert to integer v = int(line.strip().rstip()) values.append(v) return values # example usage. sum() calculates the sum of the argument(s) print(sum(read_ints_from_file("path/to/textfile.txt")))

If the file contains text other than the numbers, you should look into regular expressions (using re) to find the values.

Not tested, but whaaaaaaaa, as usual

thanks a lot!

The simple but maybe evolving tools script is here. Requires pip install pythonista-wkwebview.
