从列表生成Python中的HTML表格

Question

我现在有一份数据列表：

    list = [('ALCOA INC. CDI', 66.0), ('RIO TINTO LIMITED', 29.210000000000001), ('PLACER DOME INC CDI', 18.030000000000001), ('GUNNS LIMITED', 11.609999999999999), ('ORICA LIMITED', 10.83)] 

这是我代码生成的内容，我想把它放进一个HTML表格里。目前我只能把公司名称放进表格，尝试放入数字时却总是失败。

    print '    <table border = "1" cellpadding = "1" cellspacing = "0">'
    print '         <tr>'
    for i in list:
        print '        <td>'+i[1]+'</td>' #here is where i've tried to only input the numbers, but output isn't working.
    print '            </td>'
    print '        </tr>'
    print '    </table>'

TypeError: cannot concatenate 'str' and 'float' objects

我其实不太明白该怎么解决这个问题。

Answer 1

或者

print '        <td>%.2f</td>' % i[1]

如果你想打印出整数部分加上两位小数的话

Answer 2

你不能把字符串和浮点数直接拼接在一起，你需要把浮点数转换成字符串：

print ' <td>'+str(i[1])+'</td>'
