用Python创建HTML表格

Question

我在创建一个HTML表格时遇到了困难。我的目标是把 list、dict、tuple、str、int 和 float 的所有 dir() 输出放到一个HTML表格里，并且每行最多显示7列。我尝试了很多方法，但都没能成功。每次尝试的时候，我都会遇到内部服务器错误。我觉得可能是我在写表格标签的时候出了问题，或者我漏掉了什么，但到现在还没搞明白。

#!/usr/local/bin/python3

print('Content-type: text/html\n')

d_list = [] 
d_dict = []
d_tuple = []
d_str = []
d_int = []
d_float = []

for i in dir(list):
    d_list.append(i)
for i in dir(dict):
    d_dict.append(i)
for i in dir(tuple):
    d_tuple.append(i)
for i in dir(str):    
    d_str.append(i)
for i in dir(int):
    d_int.append(i)
for i in dir(float):
    d_float.append(i)

d_list = [d_list[i:i + 7] for i in range(0, len(d_list), 7)]
d_dict = [d_dict[i:i + 7] for i in range(0, len(d_dict), 7)]
d_tuple = [d_tuple[i:i + 7] for i in range(0, len(d_tuple), 7)]
d_str = [d_str[i:i + 7] for i in range(0, len(d_str), 7)]
d_int = [d_int[i:i + 7] for i in range(0, len(d_int), 7)]
d_float = [d_float[i:i + 7] for i in range(0, len(d_float), 7)]

td_list = []
td_dict = []
td_tuple = []
td_str = []
td_int = []
td_float = []

for i in d_list:
     td_list.append(['<td>{}</td>'.format(x) for x in i])
for i in d_dict:
     td_dict.append(['<td>{}</td>'.format(x) for x in i])
for i in d_tuple:
     td_tuple.append(['<td>{}</td>'.format(x) for x in i])
for i in d_str:
     td_str.append(['<td>{}</td>'.format(x) for x in i])
for i in d_int:
     td_int.append(['<td>{}</td>'.format(x) for x in i])
for i in d_float:
     td_float.append(['<td>{}</td>'.format(x) for x in i])

<table>
for i in td_list:
     print('<tr>' + " ".join(i) + '</tr>')
</table>
<table>
for i in td_dict:
     print('<tr>' + " ".join(i) + '</tr>')
</table>
<table>
for i in td_tuple:
     print('<tr>' + " ".join(i) + '</tr>')
</table>
<table>
for i in td_str:
     print('<tr>' + " ".join(i) + '</tr>')
</table>
<table>
for i in td_int:
     print('<tr>' + " ".join(i) + '</tr>')
</table>
<table>
for i in td_float:
     print('<tr>' + " ".join(i) + '</tr>')
</table>

试试这个

#!/usr/local/bin/python3

print('Content-type: text/html\n')

table = []
table.append("<table>\n")
for obj in [list, dict, tuple, str, int, float]:
    table.append("\t<tr>\n")
    td = []
    for key in dir(obj)[:7]:
        td.append("<td>{0}</td>".format(key))
    table.append("\t\t"+"".join(td))
    table.append("\n\t</tr>\n")

table.append("</table>")

print("".join(table))
