A computer program that translates one program instruction at a time into machine language is called a/an

A program that translates and runs one instruction at a time is an interpreter.

The CPU executes instructions but is hardware, not a translating program.

A compiler translates the whole program at once, not line by line.

A simulator imitates another system rather than translating code.

An interpreter reports an error as soon as it reaches a faulty line.

Python and BASIC are commonly run through interpreters.
