operands

This program is in response to the assignment: "Create a method named Sum() that accepts any number of integer parameters and displays their sum. Write a Main() method that demonstrates that the Sum() method works correctly when passed one, three, five, or an array of ten integers. Save the program as UsingSum.cs ." from Microsoft® Visual C#® 2008, An Introduction to Object-Oriented Programming, 3e, Joyce Farrell My code in the "//step 1:" part is getting the CS0019 error, which states that it cannot be applied to operands of type bool and int . I highly suspect there are also other problems

I'm new to python (PYTHON 3.4.2) and I'm trying to make a program that adds and divides to find the average or the mean of a user's input, but I can't figure out how to add the numbers I receive. When I open the program at the command prompt it accepts the numbers I input and would print it also if I use a print function, but it will not sum the numbers up. I receive this error: TypeError: unsupported operand type(s) for +: 'int' and 'str' My code is below: #Take the user's input numbers = input("Enter your numbers followed by commas: ") sum([numbers]) Any help would be deeply appreciated.

I cannot figure out a problem I am having with code written in Python 2.7. I am converting the references to ints, but I keep getting a type exception bad operand type for unary +: 'str' . Can anyone assist? import urllib2 import time import datetime stocksToPull = 'EBAY', 'AAPL' def pullData(stock): try: print 'Currently pulling', stock print str(datetime.datetime.fromtimestamp(time.time()).strftime('%Y-%m-%d %H:%M:%S')) urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' + \ stock + '/chartdata;type=quote;range=3y/csv' saveFileLine = stock + '.txt' try: readExistingData = open

I am a newbie to Python and have been recently attempting to create a BMI calculator, but I am having errors with the following code: def calculator(): weight = raw_input('Please enter your weight (kg):') if weight.isdigit and weight > 0: height = raw_input('Please enter your height (m):') if height.isdigit and height > 0: bmi = (weight) / (height ** 2) print "Your BMI is", bmi if bmi < 18.5: print 'You are underweight.' if bmi >= 18.5 and bmi < 25: print 'Your BMI is normal.' if bmi >= 25 and bmi < 30: print 'You are overweight.' if bmi >= 30: print 'You are obese.' else: height = raw_input(

After I run the code in matlab, I encounter this error and unsure how to solve it. How can I solve this problem. Warning: Operands to the || and && operators must be convertible to logical scalar values. Jgray = double(rgb2gray(J)); % Calculate the Gradients [dIx, dIy] = gradient(Jgray); if max(dIx)<=103 && max(dIy)<=100 B = abs(dIy) - abs(dIx); else B = abs(dIx) - abs(dIy); end user1083059 If dIx and dIy are matrices (as opposed to 1-D vectors), max(dIx) and max(dIy) will return vectors. && and || should be used to compare scalars, not vectors. You probably want to type if max(dIx(:))<=103 &&

I am trying to implement the Naive Gauss and getting the unsupported operand type error on execution. Output: execfile(filename, namespace) File "/media/zax/MYLINUXLIVE/A0N-.py", line 26, in <module> print Naive_Gauss([[2,3],[4,5]],[[6],[7]]) File "/media/zax/MYLINUXLIVE/A0N-.py", line 20, in Naive_Gauss b[row] = b[row]-xmult*b[column] TypeError: unsupported operand type(s) for -: 'list' and 'list' >>> This is the code def Naive_Gauss(Array,b): n = len(Array) for column in xrange(n-1): for row in xrange(column+1, n): xmult = Array[row][column] / Array[column][column] Array[row][column] = xmult

In C, I am able to do a trick with numbers: uint8_t value = 0 int delta = -1 uint8_t result = value + delta /* result will be 0xFF */ Is there a way of doing the same in Swift? Notice that the same approach doesn't work: let value: UInt8 = 0 let delta: Int = -1 var result: UInt8 = value + delta // Error, even typecasting in different ways... Is there a way to get C's behaviour for substraction in Swift? Thanks! All signed and unsigned integer types have a bitPattern: constructor, which creates an unsigned number from a signed (or vice versa) with the same memory representation: let delta: Int8

I'm going through the LPTHW and I came across something I cannot understand. When will it ever be the case that you want your boolean and or or to return something other than the boolean? The LPTHW text states that all languages like python have this behavior. Would he mean interpreted vs. compiled languages or duck typed vs static typed languages? I ran the following code: >>> False and 1 False >>> True and 1 1 >>> 1 and False False >>> 1 and True True >>> True and 121 121 >>> False or 1 1 >>> False or 112 112 >>> False or "Khadijah" 'Khadijah' >>> True and 'Khadijah' 'Khadijah' >>> False or
