python怎样做html的表格

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了python怎样做html的表格相关的知识,希望对你有一定的参考价值。

  现要实现python制作html格式的表格,利用Python对字符串str.format()格式化操作进行处理,在日常对CVS格式文件处理过程当中,经常会将CVS格式文件进行转换,在正式场合是程序读取CVS文件进行转换并输出到html格式的文件当中,但现在只是实现一下转换的过程,需要输入以逗号分隔的数据。

  在设计程式的时候,需要先定义一下整个代码的框架,首先我们要定义一个主函数main(),虽然Python没有规定入口函数,一般在正式的开发中都设计了一个main()函数作为程序的入口函数,或许这是一种规范吧。然后我们在定义一个打印表头的方法print_head(),并在主函数里进行调用。再定义一个打印表尾的方法print_end(),也在主函数中进行调用。定义print_line()为打印表格行,定义extract_field()处理cvs行数据转换为list集合数据。最后再定义一个处理特殊符号的方法escape_html(),因为在html代码中为了避免与它的标签冲突,特要进行特殊符号的转换,如&-->&
还有就是对长度过长的数据要进行处理并用...代替

  源代码:

  #File Csv2html.py

  #主函数

  def main():

  print_head()

  maxWidth = 100

  count = 0

  while True:

  try:

  line = str(input())

  if count == 0:

  color = "lightgreen"

  elif count%2 == 0:

  color = "white"

  else:

  color = "lightyellow"

  print_line(line, color, maxWidth)

  count += 1

  except EOFError:

  break

  print_end()

  #打印表格头

  def print_head():

  print("")

  #打印表行

  def print_line(line, color, maxWidth):

  tr = "".format(color)

  tds = ""

  if line is not None and len(line) > 0:

  fields = axtract_fields(line)

  for filed in fields:

  td = "0".format(filed if (len(str(filed)) <= maxWidth) else
(str(filed)[:100] + "..."))

  tds += td

  tr += "0

  ".format(tds)

  print(tr)

  #打印表格尾

  def print_end():

  print("")

  #抽取行值

  def axtract_fields(line):

  line = escape_html(line)

  fields = []

  field = ""

  quote = None

  for c in line:

  if c in "\"":

  if quote is None:

  quote = c

  elif quote == c:

  quote = None

  continue

  if quote is not None:

  field += c

  continue

  if c in ",":

  fields.append(field)

  field = ""

  else:

  field += c

  if len(field) > 0:

  fields.append(field)

  return fields

  #处理特殊符号

  def escape_html(text):

  text = text.replace("&", "&")

  text = text.replace(">", ">")

  text = text.replace("<", "<")

  return text

  #程序入口

  if __name__ == "__main__":

  main()

  运行结果:

  >>>

参考技术A 基于文本文档(Markdown) 设想好需要的基本需要的表、字段、类型;
使用 Rails Migration 随着功能的开发逐步创建表;
随着细节功能的开发、需求,逐步增加字段,删除字段,或者调整字段类型;
第一个 Release 的时候清理 Migrations 合并成一个;
随着后期的改动,逐步增加、修改、删除字段或表。
基本上我的所有项目都是这么搞的,这和项目是否复杂无关。
所以我前面为什么说思路需要转变。本回答被提问者和网友采纳
