Exception as flow control

Question

Is it really bad to use exception as flow control?
And if this is the case, why is it accepted in python?

Answer 1

HonFu yes something like that.

Answer 2

What do you mean with flow control?

Like for example:

try:
x = int(input())
except:
print('Please enter an int')

Instead of this?

x = input()
if not x.isdigit():
print('Please enter an int')
else:
x = int(x)
