Checking variable type in Python

Question

I am making a dice roller and came across a possible hindrance: while submiting how many dices or how many sides the dice has, I convert the input to an integer; in the case I accidentaly write a string in the input section, the code returns an error and stops.

How can I bypass this error message and display my own error message without stoping the code?
(I was thinking on checking the var type, but so far I can't recall any way of doing that)

Answer 1

try:
n = int(input())
except:
print("Please enter only integers")

Answer 2

if isinstance(var, int):
# the variable is an integer
# proceed normally
else:
# it isn't an integer
# show error message

Answer 3

alternative,

n = input()
if not n.isdigit():
print(“error”)
else:
n = int(n)
