How to use the same code but with different variables-CodePudding

I want to make a code that allows me to check if the number I have entered is really a number and not a different character. Also, if it is a number, add its string to the list.

Something like this:

numbers = []
num1 = input("Enter the first number: ")
try:
    check = int(num1)
    numbers.append(num1)
    print("The number {} has been added.".format(num1))
except ValueError:
    print("Please, enter a number")

I have to do the same for several numbers, but the variables are different, like here:

num2 = input("Enter the next number: ")
try:
    check = int(num2)
    numbers.append(num2)
    print("The number {} has been added.".format(num2))
except ValueError:
    print("Please, enter a number")

Is there any way to create a code that does always the same process, but only changing the variable?

CodePudding user response：

If you are trying to continue adding numbers without copying your code block over and over, try this:

#!/usr/bin/env python3

while len(numbers) < 5: #The five can be changed to any value for however many numbers you want in your list.
    num2 = input("Enter the next number: ")
    try:
        check = int(num2)
        numbers.append(num2)
        print("The number {} has been added.".format(num2))
    except ValueError:
        print("Please, enter a number")

Hopefully this is helpful!

Create the list in a function (returning the list). Call the function with the number of integers required.

def get_ints(n):
  result = []
  while len(result) < n:
    try:
      v = int(input('Enter a number: '))
      result.append(v)
      print(f'Number {v} added')
    except ValueError:
      print('Integers only please')
  return result

Thus, if you want a list of 5 numbers then:

list_of_numbers = get_ints(5)
