The global interpreter lock allows the running of the thread one at a time. This is used to distribute the functionality among all the virtual machines that are used. Python allows the switching between the threads to be performed by using the byte code instructions to provide platform-independence. The sys.setcheckinterval() method is used to allow the switching to occur during the implementation of the program and the instruction. This provides the understanding in the field of accounting to use the byte code implementation that makes it portable to use. The atomicity can be provided such that the shared variables can be given as built-in data types.
