Python程序未按预期提示用户

Question

I am trying to write a program that automatically removes directories provided by the users input. However, when the code is executed I don't get a prompt asking me what directories I want to remove, therefore nothing actually gets removed or printed to the screen. Where am I going wrong? Am I missing something?

I have tried adding the 'input' function inside and outside the function, although I get the same output. The only outputting I keep getting is what is contained within the print function.

from sys import argv
import subprocess
import os

print ("""This tool is designed to remove multiple or single directories from your computer. \n You'll be asked the directory of which you wish to be removed.""")

name = argv(script[0])
directoryPath = input("Enter the directory to be deleted: ")

def removeDirectory(os):
    os.system("rm -rf", directoryPath)
    if os.stat(directoryPath) == 0:
        print (directoryPath, " has been successfully deleted")
    else:
        if os.stat(directoryPath) > 0:
            print ("The directory has been removed. Try re-running the script.")

My aim is to prompt the user (me) for the directory I want to be removed, then if successful, print the message '(directory) has been successfully deleted.'

I think you have forgotten to call the function that you have defined. Here's the same code with a new line:

from sys import argv
import subprocess
import os

# Function definition must happen before the function is called
def removeDirectory(directoryPath):
    os.system("rm -rf", directoryPath)
    if os.stat(directoryPath) == 0:
        print (directoryPath, " has been successfully deleted")
    else:
        if os.stat(directoryPath) > 0:
            print ("The directory has been removed. Try re-running the script.")

print ("""This tool is designed to remove multiple or single directories from your computer. \n You'll be asked the directory of which you wish to be removed.""")

name = argv(script[0])
directoryPath = input("Enter the directory to be deleted: ")
removeDirectory(directoryPath)      # < added this line

EDIT: as someone else pointed out, you should not use "os" as a parameter to your function (since it is already being used to reference the library you imported). I've changed that in the code above.

from sys import argv
import subprocess
import os

def removeDirectory(directoryPath):
    os.system("rm -rfi {0}".format(directoryPath))
    if os.stat(directoryPath) == 0:
        print(directoryPath, " has been successfully deleted")
    else:
        if os.stat(directoryPath) > 0:
            print("The directory has been removed. Try re-running the script.")

def main():
    print("""This tool is designed to remove multiple or single directories from your computer. \n You'll be asked the directory of which you wish to be removed.""")

    name = argv(script[0])
    directoryPath = input("Enter the directory to be deleted: ")
    removeDirectory(directoryPath)

if __name__ == "__main__":
    # execute only if run as a script
    main()

I just want to personally thank everyone that tried to help me with my problem. However, I have managed to find a solution. Instead, of using the function 'os.removedirs'. I used a function called 'shutil.rmtree(directoryPath)', which removed the inputted directory without warnings. Although, I couldn't have done this without the help I have received, so thank you to everyone that got involved!
