Re: [Quantlib-users] QL Python - 'int' object is not callable

[Ben W. <ben...@ma...>]

Worked it out – they are just enumerated types not functions…

 

def roll_conventions(convention):

    if convention in ['Following','F']:

      return ql.Following

    if convention in ['ModifiedFollowing','MF']:

      return ql.ModifiedFollowing

    if convention in ['Preceding'  ,'P']:

      return ql.Preceding

    if convention in ['ModifiedPreceding','MP']:

      return ql.ModifiedPreceding

    if convention in ['Unadjusted','U']:

        return ql.Unadjusted

    return

HiHi,

 

I have a simple python function to return the roll date conventions, but get  'int' object is not callable. Very odd – any work around?

 

def roll_conventions(convention):

    if convention in ['Following','F']:

      return ql.Following()

    if convention in ['ModifiedFollowing','MF']:

      return ql.ModifiedFollowing()

    if convention in ['Preceding'  ,'P']:

      return ql.Preceding()

    if convention in ['ModifiedPreceding','MP']:

      return ql.ModifiedPreceding()

    if convention in ['Unadjusted','U']:

        return ql.Unadjusted()

    return

Regards

 

Ben
