Python class and inheritance, the preliminary understanding, where the 12th line CALSS people () add no company is the same, this is not understood.

classCompany :def __init__(self,name,birthyear,birthmonth,birthplace): Self.name=name Self.birthyear=birthyear Self.birthmonth=Birthmonth Self.birthplace=Birthplacedefdesc (self):Print('%s was created in%d%d months and was born in {0}'. Format (self.birthplace)%(self.name,self.birthyear,self.birthmonth))Print('{ 0} was created in {1} year {2} month, born in {3}'. Format (self.name,self.birthyear,self.birthmonth,self.birthplace))Print(Self.name,'created in', Self.birthyear,'years', Self.birthmonth,'Month','Born in', Self.birthplace)classPeople (company):def __init__(self,name,birthday,birthmonth,birthplace): Company.__init__(Self,name,birthday,birthmonth,birthplace)defdesc (self):Print('{ 0} was born in {1} years {2} months, {3} people'.
