Question

all. I am trying to use python 2.7.1 to run batch files based on what a user enters at the input prompt. The problem I’m having is the batch files do not run. I have been able to get a specific batch file to run from python if it is called from main() but cannot get python to select the file based on the input value. My code is:

from subprocess import Popen


def results():
    Popen("results.txt")
    selection()

def buildinga():
    Popen("5463.bat")
    results()

def base():
    Popen("base.bat")
    results()

def selection():
    print "This tool will check the device status for the specified building."
    print "Type 'exit' to quit the program."
    selection.c = input("Please enter the device number: ")


    if selection.c == "001":
        base()

    if selection.c == "5463":
        buildinga()

    if selection.c == "exit":
        exit()



def main():
    selection()


main()

The way I can run a single batch file is:

from subprocess import Popen

def batchwriter():
    Popen("make.bat")

def main():
    batchwriter()

main()

This way does not allow me to select which batch file to run, only the one specified. Any help would be much appreciated.

I tried to post this in comments but could not. raw_input is working. The batch file is being run and then the results file displays, however, errors are displayed, as well. The errors don’t seem to affect functionality because the results are correct. I am getting the following output:

This tool will check the device status for the specified building.
Type 'exit' to quit the program.
Please enter the device number: 5463

Answer 1

Use raw_input istead of input. input converts numeric input to from string to integer.

>>> input()
001
1
>>> raw_input()
001
'001'
