Python operator * * (two multiplication sign is a exponentiation)

A multiplication sign *, if the operand is two digits, which is the two numbers multiplied, such as 2*4, the result is 8
* * Two multiplication sign is the exponentiation. Like 3**4, the result is 3 of 4, and the result is 81.

* If a string, list, tuple is multiplied by an integer n, returns a homogeneous object with all its elements repeating n times, such as "str" to return the string "Strstrstr"

If the * in front of the parameter in the function definition is represented by placing multiple parameters on the call into a tuple, * * means that the keyword argument when the function is called is placed in a dictionary
Args= (a)
Func= (*args)
Equivalent to function call Func (+/-)

Print (3**4)  # The result is Bayi  = input ('input a string')print(' with str*3 Output three times str:'#* If it is a string, a list, a tuple multiplied by an integer n, returns a homogeneous object with all its elements repeating n times
