Method and System for Assisting a Software Developer in Creating Source code for a Computer Program

In a software development system, a method for assisting a user in creating source code for a computer program in a high-level programming language. The method comprises: at a current user inputting location within a piece of source code under development, detecting (405,410) a need for assisting the user with input for the creation of the piece of source code under development; determining (415) fitting source code elements suitable for input at said current inputting location; and providing, e.g. displaying (420) to the user said list of fitting source code elements, wherein, in order to determine the fitting source code elements, for each fitting source code element a respective fitting probability of the source code element in the current inputting location is determined, and wherein the user is provided with the list of fitting source code elements by associating to each fitting source code element in the list an indication of the respective fitting probability.
