a while loop is used when the number of iterations is uncertain. Note: The if statement is like a single iteration of a loop; it is used to trigger a reaction to certain conditions, or respond to an ...

If you want speed, use C, not Python. But for Pythonistas ... Don’t write a loop that calls a “Cythonized” function repeatedly; implement the loop in Cython and pass the data all at once.

The point is that Python has a way to economically express things like loops that iterate over ... Most any external code that exposes a C-compatible foreign function interface can be accessed ...

When you combine Python's dynamic typing with its generally very compact syntax, you can succinctly and clearly express complex ideas and calculations in fewer lines of code than equivalent C-family ...
