subprocess.call()

subprocess.call() is a method in the Python subprocess module that allows you to execute a command in a new process and waits for it to complete before returning the return code of the process.

The method takes one or more arguments, including the command to be executed and optional arguments that control how the command is executed, such as the working directory, environment variables, and input/output redirection.

Here's an example of how to use subprocess.call() to execute a command to print the output of a file:

import subprocess

# Define the command to execute
cmd = ["cat", "/path/to/file.txt"]

# Execute the command and wait for it to complete
return_code = subprocess.call(cmd)

# Print the return code of the command
print(f"Command returned with code: {return_code}")

In this example, subprocess.call() is used to execute the "cat" command to print the contents of a file. The return code of the command is stored in the "return_code" variable and printed to the console.
