Prompt
Resolve the merge conflict in greet.py. The base was a simple greet with print("Hello"). Branch A added f-string formatting with the name parameter. Branch B changed the greeting text to "Hi there" and changed return to False. Resolve the conflict keeping the most useful changes. Provide ONLY the resolved file content.
Expected
def greet(name): print(f"Hello, {name}") return True
