Some pseudo-code for CGPGrey. Assumes monarch is an object that has methods: - hasChildren - hasSons OR hasDaughters - hasSons - returns true if they have at least one son - hasDaughters - returns true if they have at least one daughter - sons object with eldest method that returns oldest son - daughters object with eldest method that returns ol…

def MalePrimoGenetor(monarch):
  if monarch.hasChildren is False:
    return MalePrimoGenetor(monarch.parent)  
  else 
    if monarch.hasSons is True:
      return monarch.sons.eldest
    else if monarch.hasDaughters is True:
      return monarch.daughters.eldest
    else 
      return none

Since you’re returning on each conditional, you could choose to clean up the code, by dropping the unneeded conditionals, like this:

def MalePrimoGenetor(monarch):
if monarch.hasChildren is False:
return MalePrimoGenetor(monarch.parent)

if monarch.hasSons is True:
return monarch.sons.eldest

if monarch.hasDaughters is True:
return monarch.daughters.eldest

return none

More simplified, but the intent might be more clear by leaving them in.
