I am stuck with this homework:
rewrite the following program so that it can handle any invalid inputs from user.
def example():
for i in range(3)
x=eval(input('Enter a number: '))
y=eval(input('enter another one: '))
print(x/y)
l tried tried the try... except ValueError, but the program is still failing to run.
That's because you probably didn't consider the ZeroDivisionError
that you get when y = 0!
What about
def example():
for i in range(3):
correct_inputs = False
while not correct_inputs:
try:
x=eval(input('Enter a number: '))
y=eval(input('enter another one: '))
print(x/y)
correct_inputs = True
except:
print("bad input received")
continue
This function computes exactly 3 correct divisions x/y!
If you need a good reference on continue
operator, please have a look here
