I have two quick questions:
1) Why does sys.exit() not work in a try clause (but it does in the except
clause)?
try:
... print 1
... sys.exit(0)
... except:
... print 2
... sys.exit(0)
...
1
2
# python exited
2) If opening a file fails in the below 2 cases, sys.exit(message) prints a
message in the except clause before program termination.
Some use file.close() in the except clause (or in a finally clause). It
seems superflous in the below case of read and write. (?)
try:
file = open('myinfile.txt', 'r')
except IOError:
sys.exit('Couldn't open myinfile.txt')
try:
file = open('myoutfile.txt', 'w')
except IOError:
sys.exit('Couldn't open myoutfile.txt')
