trying to get my try except block to work.
import sys
def main():
try:
test = int("hello")
except ValueError:
print("test")
raise
main()
output is
C:\Python33>python.exe test.py
test
Traceback (most recent call last):
File "test.py", line 10, in <module>
main()
File "test.py", line 5, in main
test = int("hello")
ValueError: invalid literal for int() with base 10: 'hello'
C:\Python33>
would like the except to trip
You are reraising the exception. It's working as designed.
The test is printed right at the top there before the traceback, but you used raise so the exception still is causing a traceback:
>>> def main():
... try:
... test = int("hello")
... except ValueError:
... print("test")
... raise
...
>>> main()
test
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 3, in main
ValueError: invalid literal for int() with base 10: 'hello'
Remove the raise and just the test print remains:
>>> def main():
... try:
... test = int("hello")
... except ValueError:
... print("test")
...
>>> main()
test
raise. The first sentence states:If no expressions are present, raise re-raises the last exception that was active in the current scope.
