Where anything which is an offence is made up of parts, any of which parts is itself an offence, the offender shall not be punished with the punishment of more than one of such his offences, unless it be so expressly provided.
[Where anything is an offence falling within two or more separate definitions of any law in force for the time being by which offences are defined or punished, or where several acts, of which one or more than one would by itself or themselves constitute an offence, constitute, when combined, a different offence, the offender shall not be punished with a more severe punishment than the Court which tries him could award for any one of such offences].
If the offence constitutes many parts and each part of the offence is in itself an offence under various definitions of any other law for the time being in consideration then the offender shall not be punished for more than one of such offences unless it is expressly provided.
The other part of the section states that whenever the punishable offence falls within two or more definitions of any law for time being in force or where several acts constituting an offence and one or more of such acts in itself constitutes an offence but in cases when such acts are combined then constitutes a different offence, the offender shall not be punished with more severe punishment given for each of those acts constituting an offence in itself by the court that was trying the offender.
Eg. Murder is a punishable offence and if A bought an illegal weapon to murder B then buying of an illegal weapon is in itself one of the punishable act that constitutes the offence of murder.
