What does the Star operator mean in Python?
The asterisk (star) operator is used in Python with more than one meaning attached to it.
For numeric data types, * is used as multiplication operator
>>> a=10;b=20 >>> a*b 200 >>> a=1.5; b=2.5; >>> a*b 3.75 >>> a=2+3j; b=3+2j >>> a*b 13j
For sequences such as string, list and tuple, * is a repetition operator
>>> s="Hello" >>> s*3 'HelloHelloHello' >>> L1=[1,2,3] >>> L1*3 [1, 2, 3, 1, 2, 3, 1, 2, 3] >>> T1=(1,2,3) >>> T1*3 (1, 2, 3, 1, 2, 3, 1, 2, 3)
Single asterisk as used in function declaration allows variable number of arguments passed from calling environment. Inside the function it behaves as a tuple.
>>> def function(*arg): print (type(arg)) for i in arg: print (i)
>>> function(1,2,3) <class 'tuple'> 1 2 3
