Those are built-in functions (builtin_function_or_method), not user-defined functions (function). They are implemented in C, into python library. These functions are not exposed at the Python level. 2018-10-16 08:54:43 -0500 asked a question Is there any difference between the variables b and *b in these two statements? If so, what is it?  (a, b, c) = 1, 2, 3 (a, *b, c) = 1, 2, 3  2018-10-16 06:30:20 -0500 commented answer How to implement "positional-only parameter" in a user defined function? Examples:  def fun( a, b): print(a**b) fun(a=5, b=2) # 25 fun(b=2,a=5) # 25 fun(5,2) # 25 def fun( a, b, /): print(a**b) fun(5,2) # 25 fun(a=5, b=2) # should show error  2018-10-16 06:16:38 -0500 commented answer How to implement "positional-only parameter" in a user defined function? help(pow) o/p: ----- Help on built-in function pow in module builtins: pow(x, y, z=None, /) Equivalent to x**y (with two arguments) or x**y % z (with three arguments) Some types, such as ints, are able to use a more efficient algorithm when invoked using the three argument form.  I want to know can we write a user defined function like pow (), which has positional only parameter. 2018-10-16 06:10:12 -0500 commented answer How to implement "positional-only parameter" in a user defined function? 2018-10-16 04:23:40 -0500 asked a question How to implement "positional-only parameter" in a user defined function? def fun( a, b, /): print(a,b) o/p: File "", line 1 def fun( a, b, /): ^ SyntaxError: invalid syntax 2018-10-14 14:35:46 -0500 received badge ● Supporter (source) 2018-10-14 14:29:56 -0500 commented question list as a function parameter. yes i got my solution. thanq 2018-10-14 01:57:04 -0500 commented question list as a function parameter. I can't able to understand how the outputs work. 2018-10-14 01:53:20 -0500 edited question list as a function parameter. . >>> def fun(x, b= []): ... b.append(x) ... print(x,' ',b) ... >>> fun(7) 7 [7] >>> fun([9, 7]) [9, 7] [7, [9, 7]] >>> fun([9, 8]) [9, 8] [7, [9, 7], [9, 8]] >>>
