In python, these expression seems yields the same result: inputstring='ABC'
print inputstring.lower() print lower(inputstring) print string.lower(inputstring) result: abc abc abc Question: Is the method lower() just a method for the inputstring instance( an instrance object of a string class object), or a function in the module string.py or a build-in function or sth else? Why do the three expression yield the same result "abc"? -- http://mail.python.org/mailman/listinfo/python-list
