Python- How can I run executable files in different directories for that directory?

Here is my current code:
import csv
def read_file():
# open the file in universal line ending mode
with open('C:UsersDesktopPython FilesNPV_Out4SWAT.csv') as infile:
# read the file as a dictionary for each row ({header : value})
reader = csv.DictReader(infile)
data = {}
for row in reader:
for header, value in row.items():
try:
data[header].append(value)
except KeyError:
data[header] = [value]
return data

import numpy
def get_data(var):
print var
names = data.get(var)
if var == 'Temp_degF':
array = numpy.asarray([float(i) for i in names])
array = numpy.subtract(array, 32)
array = numpy.divide(array, 1.8)
elif var == 'Slr_Langleys':
array = numpy.asarray([float(i) for i in names])
array = numpy.multiply(array, 0.04184)
elif var == 'Wind_mph':
array = numpy.asarray([float(i) for i in names])
array = numpy.multiply(array, 0.44704)
elif var == 'Precip_in_per_y':
array = numpy.asarray([float(i) for i in names])
array = numpy.multiply(array, 0.0695428953)
elif var == 'RH_pct':
array = numpy.asarray([float(i) for i in names])
array = numpy.divide(array, 100)
return array
print array

os.chdir(wd)


I'm not sure how to run an executable file that has been copied into each of the generated 1000 folders. The input parameters for the executable has been copied along with it but is generated differently as a result of write_weather_file.
I've been using os.system and os.chdir but I'm not sure how to loop it so that it'll run the executable for different directories and more than once.

How can I:

(part 2). Run the executable file, write the results to another file, delete the folder containing the executable and the inputs, and then run the executable file in the next folder?

Thank you!
