Answer 1

Try/except can be used for catching exceptions:

print ('Type in 2 numbers and then choose to add, subtract or multiply them')
try:
    num1 = int(input("Type in the first number: "))
except ValueError:
    print('This code needs a number and not a alphabet')
    num1 = 1

try:
    num2 = int(input("Type in the second number: "))
except ValueError:
    print('This code needs a number and not a alphabet')
    num2 = 1

chose = input('Type in a addition, subtraction or multiplication sign: ')
if chose == '+':
    print(num1 + num2)
elif chose == '-':
    print(f"{num1} - {num2} = ", num1 - num2)
elif chose == '*':
    print (num1 * num2)
else:
    print('The sign you have chosen is not one of the choices'

Answer 2

#check this code

a = 0
print ('Type in 2 numbers and then choose to add, subtract or multiply them')

num = int(input("Type in the first number: "))
if num != int:
    print('This code needs a number and not a alphabet')
    a = 1
    
number = int(input("Type in the second number: "))
if number != int:
    print('This code needs a number and not a alphabet')
    a = 1

chose = input('Type in a addition, subtraction or multiplication sign: ')
if chose == '+':
    print(num + number)
elif chose == '-':
    print(num - number)
elif chose == '*':
    print (num * number)
else:
    print('The sign you have chosen is not one of the choices')
    a = 1

Line 13 and Line 18

Replace variable_name with your respective variable names

if type(variable_name) != int: or if not isinstance(variable_name, int):
