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. x,y,z三个参数的的顺序是固定的,并且不能使用关键字: print(pow(2,...

In this example, the variable my_string is assigned the value of the string "This is a string." The print() function is then used to output the value of my_string to the console. The type() function returns the type of the object that is passed to it as an argument. In this case...
