Python数据压缩 | Data Compressionbz2 bz2 2.3版本的新功能。 该模块为bz2压缩库提供了一个全面的界面。它实现了一个完整的文件接口,一次性(解除)压缩功能,以及用于顺序(反)压缩的类型。 以下是bz2模块提供的功能摘要: BZ2File类实现一个完整的文件接口,包括readline(),readlines(),writelines(),seek(),等; BZ2...
添加'U'到模式以通用换行模式打开文件进行输入。任何以输入文件结尾的行将被视为'\n'Python中的行。另外,如此打开的文件将获得该属性newlines; 该属性的值是一个None(没有新行读还), ,,'\r''\n''\r\n'或者包含所有可见的新行类型的元组。通用换行符仅在阅读时可用。实例以与正常file实例相同的方式支持迭...
使用模式'r'来避免这种情况。如果不支持压缩方法,CompressionError则会引发。 如果指定了fileobj,那么它将用作 以二进制模式打开的名称文件对象的替代方案。它应该在位置0。 对于模式'w:gz','r:gz','w:bz2','r:bz2','x:gz','x:bz2',tarfile.open()接受关键字参数compresslevel(默认9)来指定该文件的压缩...

In addition there are slower compression levels achieving a quite competitive compression ratio while still decompressing at this very high speed. What is Python-LZO ? Python-LZO provides Python bindings for LZO, i.e. you can access the LZO library from your Python scripts thereby compressing ordi...

Batch size Specify how many rows are being written in each batch. Larger batch sizes improve compression and memory optimization, but risk out of memory exceptions when caching data. No Integer batchSize Select user DB schema By default, a temporary table will be created under the sink schema ...
Fast, direct electron detectors have significantly improved the spatio-temporal resolution of electron microscopy movies. Preserving both spatial and temporal resolution in extended observations, however, requires storing prohibitively large amounts of d
