New submission from Luminair <lumin...@gmail.com>:
Below are four examples of impossible code that operates on nothing. The latter
two continue silently, throwing no errors. I saw a bug sneak by because of
this. I wonder if it is within the scope of Python's design to throw Exceptions
in these situations?
x =
for x in : print("This code is never reached")
while(None): print("This code is never reached")
emptylist = []
for x in emptylist:
if emptylist[x] == "This code is never reached":
print("This code is never reached")
else: print("This code is never reached")
