如何在 IQ Option 上买卖加密货币

Pillow#

Pillow is the friendly PIL fork by Alex Clark and Contributors. PIL is the Python Imaging Library by Fredrik Lundh and Contributors.

Pillow for enterprise is available via the Tidelift Subscription. Learn more.

Overview#

The Python Imaging Library adds image processing capabilities to your Python interpreter.

This library provides extensive file format support, an efficient internal representation, and fairly powerful image processing capabilities.

The core image library is designed for fast access to data stored in a few basic pixel formats. It should provide a solid foundation for a general image processing tool.

python数据分析:绘图和可视化入门

matplotlib是一个用于创建出版质量图表的桌面绘图包(主要是2D方面)。该项目是由John Hunter于2002年启动的,其目的是为Python构建一个MATLAB式的绘图接口。matplotlib和IPython社区进行合作,简化了从IPython shell(包括现在的Jupyter notebook)进行交互式绘图。matplotlib支持各种操作系统上许多不同的GUI后端,而且还能将图片导出为各种常见的矢量(vector)和光栅(raster)图:PDF、SVG、JPG、PNG、BMP、GIF等。除了几张,本书中的大部分图都是用它生成的。
