Problem: I wanted to test if a key exists in a dictionary before updating the value for the key. I wrote the following code: if 'key1' in dict.keys(): print "blah" else: print "boo" I think this is not the best way to accomplish this task. Is there a better way to test for a key in the dictionary?

Problem : I have my web application which is throwing the below error while running in IE: “Illegal operation attempted on a registry key that has been marked for deletion” It works really fine in my Chrome but unfortunately gives the above error in production ... information on my error.
