Description
This callable is expected to return a value but is missing a return statement.
Double check that you didn't forget to return the correct value, or if the function doesn't actually return anything, fix the type annotation to -> None instead.
Bad practice
def greet(name: str) -> str:
f'Hello, {name}!' # Forgot to print or return
Recommended
def greet(name: str) -> str:
return f'Hello, {name}!'
# Alternatively,
def greet(name: str) -> None: # as this doesn't return anything
print(f'Hello, {name}!')
