如何以编程方式阻止应用程序读取计算机文件？

Question

In a language like Python for scripting, how would you stop an app from having access to reading computer files, especially sensitive system-level ones?

Edit: To be clear, I mean set permissions for that app to not have access to computer files, even after the script is done running (setting permissions).

Answer 1

You should run your python script as a non-privileged user and read a file after validating the access

# check readability of the path 
if os.access("file.txt", os.R_OK):  
    # open txt file as file 
    with open("file.tx") as file: 
        return file.read()
