An open question of the ChatGPT generated code

[Thompson-cyber]

Hi, I found that the code def infix_to_postfix was generated by ChatGPT, with the comment # these are from ChatGPT.

TheDiscordMathProblemBotRepo/helpful_modules/problem_generator.py

Lines 42 to 81 in 15be7c5

	def infix_to_postfix(infix_expression):
	precedence = {"+": 1, "-": 1, "*": 2, "/": 2, "^": 3}
	postfix_stack = []
	operator_stack = []
	operand = ""
	# Helper function to handle appending operands to the postfix stack
	def append_operand(op):
	if len(op) > 0:
	postfix_stack.append(op)
	for char in infix_expression:
	if char == " ":
	continue
	if char.isdigit():
	operand += char
	else:
	append_operand(operand)
	operand = ""
	if char == "(":
	operator_stack.append(char)
	elif char == ")":
	while operator_stack and operator_stack[-1] != "(":
	postfix_stack.append(operator_stack.pop())
	if operator_stack:
	operator_stack.pop() # Discard the '('
	else:
	while operator_stack and precedence.get(
	operator_stack[-1], 0
	) >= precedence.get(char, 0):
	postfix_stack.append(operator_stack.pop())
	operator_stack.append(char)
	append_operand(operand)
	# Append remaining operators from operator stack to postfix stack
	while operator_stack:
	postfix_stack.append(operator_stack.pop())
	return postfix_stack

My question is whether there may be a license issue with this code. I noticed that this code is very similar to def calculate_expression in the laketree2/BOJ_pythonex repository.

• The ChatGPT-generated code was updated in Jul 2024, while the similar code was updated in 2023.

• def infix_to_postfix is protected by the AGPL-3.0 license. However, the similar code is under a No License license. According to the conditions of this No License license:

If you find software that doesn’t have a license, that generally means you have no permission from the creators of the software to use, modify, or share the software.

How do you view potential license conflicts between ChatGPT-generated code and existing open-source code?

If a license violation exists, would you add some explanation regarding the ChatGPT-generated code?

Thank you for your attention to this matter. 😊

Thank you so much for pointing this out!

I didn't do my research when I asked ChatGPT to create this problem, and I promise to try my best to see if other similar code already exists that I can't use.

Thanks for your quickly reply. 👍
