It looks like you are using Python 3.x. One of the important differences in Python 3.x is the way division is handled. When you do x / y, an integer is returned in Python 2.x because the decimal is truncated (floor division). However in 3.x, the / operator performs ‘true’ division, resulting in a float instead of an integer (e.g. 1 … Read more
Using the implicit booleanness of the empty list is quite pythonic.
You can use a loop: In Python 2, you can also use If you’re keen on a single function call, at least remove the square brackets [], so that the strings to be printed get made one at a time (a genexp rather than a listcomp) — no reason to take up all the memory required … Read more
An “incomplete class” is one declared but not defined. E.g. as opposed to You need to #include “wielrenner.h” in dokter.ccp
Use numpy.array to use shape attribute. NOTE X.shape returns 3-items tuple for the given array; [n, T] = X.shape raises ValueError.
I want to get the unique values from the following list: The output which I require is: This code works: is there a better solution I should use?
Use lists unless you want some very specific features that are in the C array libraries. python really has three primitive data structures More on data structures here: http://docs.python.org/tutorial/datastructures.html
Perform a union, keeping repetition: Perform a union, keeping repetition & order: Perform an union, no repetition in each list, but repetition allowed in final union, and keeped order: After clarification of the question, the goal is to build a list that take elements (including repetition) of, and then add elements of b if they … Read more
