Question

I have a Python script that is successfully processing single files. I am trying to write a for loop to have it get all the files in a directory that the user inputs. However, it is only processing one of the files in the directory.

The code below is followed by the rest of the script that does the analysis on data. Do I need to somehow close the for loop?

import os

print "Enter the location of the files: "; directory = raw_input()
path = r"%s" % directory

for file in os.listdir(path):
    current_file = os.path.join(path, file)

    data = open(current_file, "rb")

    # Here's an abridged version of the data analysis

    for i in range(0, 10):
        fluff = data.readline()

    Input_Parameters = fluff.split("\t")

    output.write("%f\t%f\t%f\t%f\t%.3f\t%.1f\t%.2f\t%.2f\t%s\n" % (Voc, Isc, Vmp, Imp, Pmax, 100 * Eff, IscErr, 100 * (1 - (P2 / Pmax)), file))
    data.close()

Answer 1

The current code in your answer looks basically OK to me. I noticed that it’s writing to the same output file for each of the files it processes, so that may lead you to think it’s not processing them all.
