This article is about Windows under the Python Integrated development Environment-spyder installation and use, interested in the reference of students. Spyder Introduction
Spyder is a simple integrated development environment developed by the author of Python (x,y) for it. Compared with other Python development environments, its greatest advantage is to imitate the "workspace" function of Matlab, it is easy to observe and modify the value of the array. 1. Installation Tools pip:https://pip.pypa.io/en/latest/installing.html
Download get-pip.py.
Run cmd: "Python get-pip.py".
Note: The Python 2.7.9 and 3.4 versions already contain the PIP by default, so you are not allowed to install it. 2. Install Pyside
Switch to C:\Program files (x86) \python27\scripts: "CD C:\Program files (x86) \python27\scripts".
CMD: "C:\Program Files (x86) \python27\scripts>pip install--use-wheel pyside".
Note: Pyside is a python-bound version of QT for Cross-platform application frameworks. In August 2009, Pyside first published. Provides similar functionality to PYQT and compatible APIs. But unlike PyQt, the LGPL authorization is used. 3. Install Spyder
CMD: "C:\Program Files (x86) \python27\scripts>pip install Spyder". 4. Start Spyder
Run: "C:\Program Files (x86) \python27\scripts\spyder.bat".
The following figure: You can set breakpoints, Single-step debugging, and so on.
Spyder features a lot more, here are only some common features and techniques: The default configuration, the Variable Explorer pane does not display a variable that begins with an uppercase letter, you can click the Configuration button (the last button) in the toolbar to cancel the "Exclude" in the menu. Capitalized the selected state of the references. In the console, you can press the TAB key to complete the automatic completion. When you enter "?" after the variable name, you can view the object's documentation in the Inspector pane. The show source option in the Options menu of this pane opens the source program for the display function. You can modify the work path through the Working directory toolbar, which will be the current path when the user program runs. For example, if we only need to modify the work path, we can use the same program to process the data files in different folders. You can quickly jump to the defined location by holding down the CTRL key in the Program editing window and clicking the variable name, function name, class name, or module name. If it is defined in another program file, the file is opened. When learning about the use of a new module, we often need to see how a function or class in a module is implemented, and this feature helps us to quickly view and analyze the source programs for each module. For example, the following program loads modules and classes from a different extension library. Open this file with Spyder, hold down the CTRL key, and click Signal, PL, hastraits, Instance, View, Item, Lfilter, Plot, title, open the program file that defines them, and jump to the appropriate line.
