eval(), exec() and compile()

eval evaluates an expression string, exec runs statements, compile turns source into a code object.

Intermediate

eval("2 + 3 * 4")          # 14
exec("x = 5")
code = compile("a * b", "<expr>", "eval")

Never pass untrusted input to eval/exec — it can run any code. Use ast.literal_eval to safely parse literals like "[1, 2]".
