Write a function that computes and returns the sum of the digits in an integer. Use the following function header: def sum_digits(number): For example sum_digits(234) returns 9. Use the % operator to extract the digits and the // operator to remove the extracted digit. For example, ...
It is common to say that a function “takes” an argument and “returns” a result. The result is also called the return value. Python provides functions that convert values from one type to another. The int function takes any value and converts it to an integer, if it can, or complai...
When you call a function, your code doesn't resume execution until that function returns Consider this code fragment: void foo() { while (true) { bar(); baz(); } } Whenfoocallsbar(), andbarhas not yet returned, doesfoocontinue executing? Doesbazget called beforebarreturns?
Define a function in a filenamed stat.mthat returns the mean and standard deviation of an input vector. function[m,s] = stat(x) n = length(x); m = sum(x)/n; s = sqrt(sum((x-m).^2/n));end Call the function from the command line. ...
