(d) Control returns to the point just before the function was called.

A statement that controls the execution of other statements is called a

(c) control structure

A successor to ASCII that includes characters from (nearly) all written languages is

(c) Unicode

When a program is being run directly (not imported), the value of __name__ is

(c) __main__

One difference between a compiler and an interpreter is

(c) a compiler is no longer needed after a program is translated

(a) open

What function gives the Unicode value of a character?

(a) ord

A function can send output back to the program with a(n)

(a) return
