The memory usage of Python 3.3 is two to three times smaller than Python 3.2, and a little bit better than Python 2.7, on a Django benchmark (see the PEP for details).... If Python has write-access for the directory where the Python program resides, it will store the compiled byte code in a file that ends with a .pyc suffix. If Python has no write access, the program will work anyway. The byte code will be produced but discarded when the program exits.
Python 3 Note: In Python 3.x, there is no function named xrange. This uses the special Python value None to indicate that the iterator has reached its end. This is a common Python convention. But if you need to use None as a valid item in your sequence of values, then it is easy enough to define some other unique value (e.g. a custom dummy class) to represent the end of the list. Exercises how to keep your room cool without ac What exactly do you mean by "I want the program to end while num is '4'"? Please try to describe the end condition in other words. It seems that we have problems to understand you. Please try to describe the end condition in other words.
If you prefer the alias python=python3, then some program.py without a shebang could be executed by invoking the aliased interpreter like this python program.py. Aliasing may also be useful for systems with multiple version of python3 like 3.4 and 3.6 together. how to find the independent variable in an article If you prefer the alias python=python3, then some program.py without a shebang could be executed by invoking the aliased interpreter like this python program.py.
