PrettyTable介绍¶
Python通过prettytable模块可以将输出内容如表格方式整齐的输出。
使用该模块，用户可以在日志中输出清晰的日志文档。
常用方法如下：¶
sortby - name of field to sort rows byreversesort - True or False to sort in descending or ascending orderint_format - controls formatting of integer datafloat_format - controls formatting of floating point dataadd_row(row)"""Add a row to the table Arguments: row - row of data, should be a list with as many elements as the table has fields"""del_row(row_index)"""Delete a row to the table Arguments: row_index - The index of the row you want to delete. Indexing starts at 0."""add_column(fieldname, column, align="c", valign="t")"""Add a column to the table. Arguments: fieldname - name of the field to contain the new column of data column - column of data, should be a list with as many elements as the table has rows align - desired alignment for this column - "l" for left, "c" for centre and "r" for right valign - desired vertical alignment for new columns - "t" for top, "m" for middle and "b" for bottom"""clear_rows()"""Delete all rows from the table but keep the current field names"""clear()"""Delete all rows and field names from the table, maintaining nothing but styling options"""
示例如下：
