3、shelve序列化时找错误(_pickle.UnpicklingError: pickle data was truncated)找了好久,主要原因是shelve实例打开时使用完立马要关闭(被关闭不一定每次报错,主要还是要看下一次写入数据的复杂度),准备下次的使用 4、school_data = shelve.open(BASE_DIR + r"\school_data",writeback=True),中writeback=True参数...

pickle,用于python特有的类型和python的数据类型间进行转换 Json模块提供了四个功能:dumps、dump、loads、load Pickle模块提供了四个功能:dumps、dump、loads、load shelve 模块 shelve模块是一个简单的k,v将内存数据通过文件持久化的模块,可以持久化任何pickle可支持的python数据格式 import shelve d = shelve.open('sh...

The TextWrapper class has two new attributes/constructor arguments: max_lines, which limits the number of lines in the output, and placeholder, which is a string that will appear at the end of the output if it has been truncated because of max_lines. Building on these capabilities, a new...
If you do not specify a length it defaults to a TINYBLOB (up to 255 characters), which will easily lead to errors like "Pickle data truncated." Specify a length that will satisfy all your needs. In SQLite While by default you can store 1GB per row / cell, sqlite's query size li...

Previously it was truncated. Submenus now call all hooks, it used to just call precmd and postcmd. Enhancements Automatic completion of argparse arguments via cmd2.argparse_completer.AutoCompleter See the tab_autocompletion.py example for a demonstration of how to use this feature cmd2 no ...
