The key differences between Python 2.7.x and Python 3.x with examples | Spartan Ideas. Primary Source: Sebastian Raschka Many beginning Python users are wondering with which version of Python they should start. My answer to this question is usually something along the lines “just go with the version your favorite tutorial was written in, and check out the differences later on.” But what if you are starting a new project and have the choice to pick?
In my opinion, there is no “right” or “wrong” as long as both Python 2.7.x and Python 3.x support the libraries that you are planning to use. However, it is worthwhile to have a look at the major differences between those two most popular versions of Python to avoid common pitfalls when writing the code for either one of them, or if you are planning to port your project.

Jusqu'à présent, nous avons utilisé Python exclusivement « en mode texte ». Nous avons procédé ainsi parce qu'il nous fallait absolument d'abord dégager un certain nombre de concepts élémentaires ainsi que la structure de base du langage, avant d'envisager des expériences impliquant des objets informatiques plus élaborés (fenêtres, images, sons, etc.).
Nous pouvons à présent nous permettre une petite incursion dans le vaste domaine des interfaces graphiques, mais ce ne sera qu'un premier amuse-gueule : il nous reste en effet encore bien des choses fondamentales à apprendre, et pour nombre d'entre elles l'approche textuelle reste la plus abordable. 8.1. Interfaces graphiques (GUI)▲ Si vous ne le saviez pas encore, apprenez dès à présent que le domaine des interfaces graphiques (ou GUI : Graphical User Interface) est extrêmement complexe. 8.2. Pour la suite des explications, nous supposerons bien évidemment que le module Tkinter a déjà été installé sur votre système. 8.3. 8.3.1. 8.1. 8.2.
GIT IT Jacques Grelet. Plot in 3d using python. Plot in 3d using python. Getting started An Axes3D object is created just like any other axes using the projection=‘3d’ keyword. Create a new matplotlib.figure.Figure and add a new axes to it of type Axes3D: import matplotlib.pyplot as pltfrom mpl_toolkits.mplot3d import Axes3Dfig = plt.figure()ax = fig.add_subplot(111, projection='3d') New in version 1.0.0: This approach is the preferred method of creating a 3D axes.
Note Prior to version 1.0.0, the method of creating a 3D axes was different. Line plots Axes3D.plot(xs, ys, *args, **kwargs) Plot 2D or 3D data. Other arguments are passed on to plot() (Source code, png, hires.png, pdf) Scatter plots Axes3D.scatter(xs, ys, zs=0, zdir='z', s=20, c='b', *args, **kwargs) Create a scatter plot. Keyword arguments are passed on to scatter(). Returns a Patch3DCollection (Source code, png, hires.png, pdf) Wireframe plots Axes3D.plot_wireframe(X, Y, Z, *args, **kwargs) Plot a 3D wireframe. Keyword arguments are passed on to LineCollection. Returns a Line3DCollection Surface plots Examples: Text. Nemo codes... some details.
