In python, are strings mutable?  The line someString[3] = "a" throws the error 


  TypeError: 'str' object does not
  support item assignment


I can see why (as I could have written someString[3] = "test" and that would obviously be illegal) but is there a method to do this in python?


Question: Word for the opposite of "hypochondriasis"
Answer: A widely used antonym for hypochondriac is "stoic." Spelt without a leading capital, it doesn't refer to the Stoic school of philosophy but to the general idea of ignoring or minimizing setbacks and unfavorable information.
