Turn string to integer only if it's possible.

Question

a = input("- ")
if int(a) == a:
a = int(a)
else:
print("your input isn't an integer")
It doesn't work because
str(a) == int(a) -----> False
but...
float(a) == int(a) -----> True
How can I turn a str to a int, but without an error if I don't put an integer?
Thanks (sorry if i have a bad english)

Answer 1

Use try , except block.
try:
number=int(input())
except:
number=0

Answer 2

I type the float to int example because I can turn a float to an integer only if it's ".0":
x = float(input("- "))
if x == int(x):
print(int(s))
else:
print(x)
