What is the difference between `subprocess.run()` and `subprocess.Popen()`?

Q: What is the difference between `subprocess.run()` and `subprocess.Popen()`?

> * **`subprocess.run()`**: Synchronous/blocking. It runs the command, waits for it to complete, and returns a `CompletedProcess` instance. * **`subprocess.Popen()`**: Asynchronous/non-blocking. It spawns the command in a background process immediately and allows the Python script to continue running concurrently, interacting with standard streams in real time.

💬Answer

subprocess.run(): Synchronous/blocking. It runs the command, waits for it to complete, and returns a CompletedProcess instance.
subprocess.Popen(): Asynchronous/non-blocking. It spawns the command in a background process immediately and allows the Python script to continue running concurrently, interacting with standard streams in real time.
