python prettytable模块


简介

Python通过PrettyTable模块可以将输出内容如表格方式整齐地输出。

摘自prettytable文档

  • border - 布尔类型参数(必须是True或False)。控制表格边框是否显示。
  • header - 布尔类型参数(必须是True或False)。控制表格第一行是否作为表头显示。
  • header-style - 控制表头信息的大小写。允许的参数值:“cap”(每个单词首字母大写),“title”(除了介词助词首字母大写),“lower”(全部小写)或者None(不改变原内容格式)。默认参数为None。
  • hrules - 设置表格内部水平边线。允许的参数值:FRAME,ALL,NONE。注意这些是在prettytable模块内部定义的变量,在使用之前导入或用类似prettytable.FRAME的方法调用。
  • vrules - 设置表格内部竖直边线。允许的参数值:FRAME,ALL,NONE。
  • align - 水平对齐方式(None,“l”(左对齐),“c”(居中),“r”右对齐)
  • valign - 垂直对齐方式(None,“t”(顶部对齐),“m”(居中),“b”底部对齐)
  • int_format - 控制整型数据的格式。
  • float_format - 控制浮点型数据的格式。
  • padding_width - 列数据左右的空格数量。(当左右padding未设置时生效)
  • left_padding_width - 列数据左侧的空格数量。
  • right_padding_width - 列数据右侧的空格数量。
  • vertical_char - 绘制竖直边线的字符,默认为“|”
  • horizontal_char - 绘制水平边线的字符,默认为“-”
  • junction_char - 绘制水平竖直交汇点的字符,默认为“+”

  • border - A boolean option (must be True or False). Controls whether or not a border is drawn around the table.
  • header - A boolean option (must be True or False). Controls whether or not the first row of the table is a header showing the names of all the fields.
  • header_style - Controls capitalisation of field names in the header. Allowed values: “cap” (capitalise first letter of each word), “title” (title case), “upper” (all upper-case), “lower” (all lower-case) or None (don’t change from original field name setting). Default is None.
  • hrules - Controls printing of horizontal rules after rows. Allowed values: FRAME, ALL, NONE - note that these are variables defined inside the prettytable module so make sure you import them or use prettytable.FRAME etc.
  • vrules - Controls printing of vertical rules between columns. Allowed values: FRAME, ALL, NONE
  • align - Horizontal alignment (None, “l” (left), “c” (centre), “r” (right))
  • valign - Vertical alignment (None, “t” (top), “m” (middle) or “b” (bottom))
  • int_format - Controls formatting of integer data. This should be a string which can be placed between “%” and “d” in something like print “%d” % 42.
  • float_format - Controls formatting of floating point data. This should be a string which can be placed between “%” and “f” in something like print “%f” % 4.2.
  • padding_width - Number of spaces on either side of column data (only used if left and right paddings are None).
  • left_padding_width - Number of spaces on left hand side of column data.
  • right_padding_width - Number of spaces on right hand side of column data.
  • vertical_char - Single character string used to draw vertical lines. Default is |.
  • horizontal_char - Single character string used to draw horizontal lines. Default is -.
  • junction_char - Single character string used to draw line junctions. Default is +.

用法
x = PrettyTable() 
x.border = False 
x.header = False 
x.padding_width = 5
  • 1
  • 2
  • 3
  • 4
x = PrettyTable(border=False, header=False, padding_width=5)
  • 1

以上两种设置方式等效

调整对齐方式的几种方法
print(x.get_string(align="l"))
  • 1
x.align["City name"] = "l" 
x.align["Population"] = "c" 
x.align["Area"] = "r"
  • 1
  • 2
  • 3
x.align = "l'
  • 1
