Overloading

Can not believe it for an overloading in programming OOP (Object Oriented Programming), It was very in need in a class called repeatedly with different parameters in the same class and the same method, it does not mean overriding. As in VB.Net:

	'with difference parameters on Time
	Module overLoadingVB
	Sub Main()
	' use overloaded constructors
	Dim time1 As New timeOn()
	Dim time2 As New timeOn(4)
	Dim time3 As New timeOn(24, 34)
	Dim time4 As New timeOn(time3) ' use time4 as initial value
	Console.WriteLine(time1.stringUniversal() )
	Console.WriteLine(time2.stringUniversal() )
	Console.WriteLine(time3.stringUniversal())
	Console.WriteLine(time4.stringUniversal())
	End Sub ' Main
	End Module
	Class timeOn
	Inherits Object
	Private mHour As Integer ' 0 - 23
	Private mMinute As Integer ' 0 - 59
	Private mSecond As Integer ' 0 - 59
	Public Sub New() ' Overloading Constructors default
	setTime()
	End Sub ' New
	Public Sub New(ByVal hourValue As Integer) ' Overloading Constructors 1 Parameter
	setTime(hourValue)
	End Sub ' New
	Public Sub New(ByVal hourValue As Integer, _ ' Overloading Constructors 2 Parameter
	ByVal minuteValue As Integer)
	setTime(hourValue, minuteValue)
	End Sub ' New
	Public Sub New(ByVal timeValue As timeOn) ' Overloading Constructors with class on Constructors 2 Parameters
	setTime(timeValue.mHour, timeValue.mMinute)
	End Sub ' New
	Public Sub setTime(Optional ByVal hourValue As Integer = 0, _
	Optional ByVal minuteValue As Integer = 0, _
	Optional ByVal secondValue As Integer = 0)
	If (hourValue >= 0 AndAlso hourValue < 24) Then
	mHour = hourValue
	Else
	mHour = 0
	End If
	If (minuteValue >= 0 AndAlso minuteValue < 60) Then
	mMinute = minuteValue
	Else
	mMinute = 0
	End If
	If (secondValue >= 0 AndAlso secondValue < 60) Then
	mSecond = secondValue
	Else
	mSecond = 0
	End If
	End Sub ' setTime
	Public Function stringUniversal() As String 'String Universal
	Return String.Format("{0}:{1:D2}:{2:D2}", _
	mHour, mMinute, mSecond)
	End Function ' stringUniversal
	End Class

different from the python, in python there are several constructors, but it's rather difficult when compared to Java or Dot Net. like the __init__ constructor, the constructor can not be overloading the constructor of the same name before, just be overloading the operator or by the same constructor, but do not know in their use?
misalnya seperti :

class com:
    def __init__(self):
        print "original constructor"
    def __init__(self, val1):
        print "second overloading"
    def __init__(self, val1, val2):
        print "thrid overload"

this is wrong. because in python does not apply to any such provisions.

What about python?
