Python Beginner Tutorial 6 - Exceptions and Loops
kostastergiou replied to Kevin's topic in Python Beginner Series
Can someone explain to me what validInput = False does? Not only that but also everything that is somehow linked to that. Furthermore, I really don't understand why you would define the runOperation function... Thanks in advance! -
Or use this: #include <iostream> #include <cstdlib> /* run this program using the console pauser or add your own getch, system("pause") or input loop */ using namespace std; float addition(float num1, float num2) { return num1 + num2; } float subtraction(float num1, float num2) { return num1 - num2; } float multiplication(float num1, float num2) { return num1 * num2; } float division(float num1, float num2) { return num1 / num2; } int main() { float num1; float num2; int choice; cout << "" << endl; cout << "What would you like to do? \n \n 1= Addition \n 2= Subtraction \n 3= Multiplication \n 4= Division \n" << endl; cout << "_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ \n" << endl; cout << "choice: "; cin >> choice; if(choice==1) { cout << "" << endl; //Addition cout << "ADDITION. \n \nEnter the numbers you would like to add. \n \n Number1: "; cin >> num1; cout << "\n"; cout << " Number2: "; cin >> num2; cout << "\n"; cout << " Answer = " << addition(num1, num2) << endl; } else if(choice==2) { cout << "" << endl; //Subtraction cout << "SUBTRACTION. \n \nEnter the numbers you would like to subtract. \n \n Number1: "; cin >> num1; cout << "\n"; cout << " Number2: "; cin >> num2; cout << "\n"; cout << " Answer = " << subtraction(num1, num2) << endl; } else { if(choice==3) { cout << "" << endl; //Multiplication cout << "MULTIPLICATION. \n \nEnter the numbers you would like to multiply. \n \n Number1: "; cin >> num1; cout << "\n"; cout << " Number2: "; cin >> num2; cout << "\n"; cout << " Answer = " << multiplication(num1, num2) << endl; } else { if(choice==4) { cout << "" << endl; //Divition cout << "DIVITION. \n \nEnter the numbers you would like to divide. \n \n Number1: "; cin >> num1; cout << "\n"; cout << " Number2: "; cin >> num2; cout << "\n"; cout << " Answer = " << division(num1, num2) << endl; } } } return 0; }

Python Beginner Tutorial 4 - User Input and Types
Pips replied to Kevin's topic in Python Beginner Series
The only thing I can see wrong with it is this line operation = raw_input('What do you want to do (+,-,*,/): ') which should be operation = input('What do you want to do (+,-,*,/): ') assuming all the other functions are present. -
The print statement on line 27 is missing a final closing bracket print(divide(var1,var2))
-
if (operation == "+"): print(add(var1,var2)) elif(operation == '-'): print(sub(var1,var2)) elif (operation == "*"): print(mult(var1,var2)) elif (operation == "/"): print(div(var1 / var2)) I corrected 2 things you can see them here

this is a simple calculator program but it is giving a syntax error at line 24 i am not able to figure it out what is the problem anybody can help me with this calculator.py

Few programs start with all of their features, so the first version will only implement the basics. First a couple of definitions: A variable is a value that is subject to change, and they are used a lot in Python. Whenever you need your program to "remember" something, you use a variable. In fact, almost all the information that code works with is stored in variables. For example, in the math equation x + 5 = 20, the variable is x, because the letter x is a placeholder for a value. An integer is a number; it can be positive or negative. For example, 1 and -1 are both integers. So are 14, 21, and even 10,947. Variables in Python are easy to create and easy to work with. This initial version of the dice game uses two variables: player and ai. Type the following code into a new text file called dice_alpha.py: import random player = random.randint(1,6) ai = random.randint(1,6) if player > ai : print("You win") # notice indentation else: print("You lose") Launch your game to make sure it works. This basic version of your dice game works pretty well. It accomplishes the basic goals of the game, but it doesn't feel much like a game. The player never knows what they rolled or what the computer rolled, and the game ends even if the player would like to play again. This is common in the first version of software (called an alpha version). Now that you are confident that you can accomplish the main part (rolling a die), it's time to add to the program.
