An attempt is a conduct performed in the commission of an offense that is not accomplished.
An attempt is punishable only if specifically so provided and the punishment may be reduced from that for an accomplished offense.

A conduct that is impossible to accomplish the intended offense and is not dangerous is not punishable.

If a conduct is performed in the commission of an offense and the actor voluntarily renounces the act or prevents it from producing its result, the punishment shall be reduced or remitted. This provision shall also apply to a case when the result does not occur but not due to the act of prevention by the actor so long as the actor has done his utmost to prevent it.
The provisions of the preceding paragraph applies to one or multiple joint offenders who voluntarily prevent the occurrence of the result, or who have done their utmost to prevent it but the non-occurrence of the result is not due to the act of prevention.
