Only allowing Integer input in python 3.3.2


Only allowing Integer input in python 3.3.2

Hope this helps A couple of things you could look for in your code:
using try/catch is the recommended way to test input for many reasons including knowing the exact cause of the error you can reduce some of your ifs and elses by thinking a little more about how they are nested having the function call itself and using a while loop isn't the best way, use one or the other in your case, you don't really need to allow only integer input, what you're looking for is to only allow a 0, 4, 6, or 12, which you do with the if statement
code :
from random import randint
def simul():
    while True:
        try:
            dice = int(input("What sided dice would you like to" \
                    " roll? 4, 6 or 12? 0 to not roll: "))
            if dice not in (4, 6, 12, 0):
                raise ValueError()
            break  # valid value, exit the fail loop
         except ValueError:
            print("You must enter either 4, 6, 12, or 0")

    if dice == 0:
        return 0

    print(randint(1, dice))
    return dice

if __name__ == '__main__':
    while simul() != 0:
        pass

will be helpful for those in need raw_input returns a string. Thus, you're trying to do "1" > 4. You need to convert it to an integer by using int
If you want to catch whether the input is a number, do:
code :
while True:
    try:
        ChoosePlayer = int(raw_input(...))
        break
    except ValueError:
        print ("Numbers only please!")
 print "player 0 has chosen player {}!".format(ChoosePlayer)

like below fixes the issue Ok so i've been using inputmask in my asp mvc project too, and i got the same problem.
I've tried many things and managed to get it to work by adding it in a javascript right:
code :
@Html.TextBoxFor(model => model.Contract.ContractPeriodInWeeks, 
        new { style = "width:30px" })
<script type="text/javascript">
    $('#Contract_ContractPeriodInWeeks').inputmask('99');
</script>
Python not allowing variables in input

To fix this issue input expects a string as an argument so you can't pass it multiple args like with print. Instead you can format the string before you pass it to input:
code :
var = 1
var1 = input(f"Hey var = {var} Bye : ")
Why angularjs(ng-repeat) allowing to add duplicate record at first time if the input array values are integer types

Why angularjs(ng-repeat) allowing to add duplicate record at first time if the input array values are integer types

To fix the issue you can do It is because by default input type is text therefore string, so number 2 is not equel to string "2"
if you add type number to your input
code :
<input type="number" ng-model="addMe"> 
var app = angular.module("myShoppingList", []);
app.controller("myCtrl", function($scope) {
  $scope.products = [1, 2, 3];
  $scope.addItem = function() {
    $scope.products.push($scope.addMe);
  }
});

      <input type="number" ng-model="addMe">

How can I get interactive Python to avoid using readline while allowing utf-8 input?

help you fix your problem In the past, I've disabled Python readline by rebuilding it from source: configure --disable-readline
This might be overkill, though, for your situation.
