   Feb 26, 2012 · 73. Python has a compiler! You just don't notice it because it runs automatically. You can tell it's there, though: look at the .pyc (or .pyo if you have the optimizer turned on) files that are generated for modules that you import. Also, it does not compile to the native machine's code.

   Aug 11, 2024 · The function in question is sum(). One of the primary reasons for using this function is readability. Instead of having to write for loops or recursions, sum() takes care of all that for you. The sum() function wasn’t introduced until Python 2.3 and serves as a Pythonic solution to summing numbers. Using sum() is very easy. For instance:

   Python’s built-in function sum() is an efficient and Pythonic way to sum a list of numeric values. Adding several numbers together is a common intermediate step in many computations, so sum() is a pretty handy tool for a Python programmer. As an additional and interesting use case, you can concatenate lists and tuples using sum(), which can ...

   Why do we need a built-in sum() function in Python?

   • One reason for implementing a built-in sum() function could be convenience. Writing a single function call rather than a for-loop with a counter is simply much faster and concise. However, there’s more to it. In Python, you can define the so-called magic dunder methods for a class to implement specific functionalities.
