Identify the Correct extension that should be used when saving a Python program as a file..exe extension.pyt extension.py extension.txt extension

Breakdown the Problem

1. We need to determine the correct file extension for saving a Python program.
2. We are given several options: .exe, .pyt, .py, and .txt.

Relevant Concepts

1. File extensions indicate the type of file and which program can open or execute it.
2. Python source code is typically saved with the .py extension.

Analysis and Detail

1. .exe: This is an executable file format used mostly for Windows applications. Python scripts are not directly saved as .exe.
2. .pyt: This is not a standard extension used for Python; it doesn't correspond to any known file type in Python development.
3. .py: This is the standard file extension for Python script files. It indicates that the file contains Python code that can be executed by the Python interpreter.
4. .txt: This is a plain text file format, and while Python code can be saved in a .txt file, it would not be recognized as an executable Python script.

Verify and Summarize

After analyzing the options, the correct file extension for saving a Python program is .py, as it is specifically designed for Python source code.

Final Answer

The correct extension to save a Python program as a file is .py.
