将 Python 字典输入到 html 表中

Question

Is there any way to print the python dictionary in to a table in HTML. I have a python dictionary and am sending to HTML by using

return render_template('index.html',result=result)

Now I need to print the elements in result dictionary in to HTML as a table.

Answer 1

Flask uses Jinja as the templating framework. You can just do the following in your template (html)

<table>
{% for key, value in result.iteritems() %}
   <tr>
        <th> {{ key }} </th>
        <td> {{ value }} </td>
   </tr>
{% endfor %}
</table>

Answer 2

I've had better luck putting the dictionary into a list of lists, then have the html loop through the list and print the table. The python would be:

Table = []
for key, value in results_dict.iteritems():    # or .items() in Python 3
    temp = []
    temp.extend([key,value])  #Note that this will change depending on the structure of your dictionary
    Table.append(temp)

Then in your html you loop through the table.

<table>
{% for t in table %}
    <tr>
    {% for i in t %}
        <td>{{ i }}</td>
    {% endfor %}
    </tr>
{% endfor %}
 </table>

Answer 3

Check Flask-Table .

Example from the docs (slightly edited):

from flask_table import Table, Col

# Declare your table
class ItemTable(Table):
    name = Col('Name')
    description = Col('Description')

items = [dict(name='Name1', description='Description1'),
         dict(name='Name2', description='Description2'),
         dict(name='Name3', description='Description3')]

# Populate the table
table = ItemTable(items)

# Print the html
print(table.__html__())
# or just {{ table }} from within a Jinja template

Answer 4

For python3, no () after result.items

<table>
{% for key, value in result.items %}
   <tr>
        <th> {{ key }} </th>
        <td> {{ value }} </td>
   </tr>
{% endfor %}
</table>

Answer 5

so I wanted an easy way to generate html from python dictionary with only inline styles (because emails) and couldn't find anything that I was satasfied with so I wrote this,

it's very simple to use and easy to add styles to

 <table style="margin: 3px"> <tr style="background-color: #7cc3a97d"> <th style="color: white">col1</th> <th style="color: white">col2</th> <th style="color: white">col3</th> <th style="color: white">col4</th> </tr> <tr style="background-color: aliceblue"> <td style="padding: 1rem">value11</td> <td style="padding: 1rem">value21</td> <td style="padding: 1rem">value31</td> <td style="padding: 1rem">value41</td> </tr> <tr style="background-color: #c2d4e4"> <td style="padding: 1rem">value12</td> <td style="padding: 1rem">value22</td> <td style="padding: 1rem">value32</td> <td style="padding: 1rem">value42</td> </tr> <tr style="background-color: aliceblue"> <td style="padding: 1rem">value13</td> <td style="padding: 1rem">value23</td> <td style="padding: 1rem">value33</td> <td style="padding: 1rem">value43</td> </tr> </table>

lets say you have the following dictionary

myDict = {
    'col1' : ['value11', 'value12', 'value13'],
    'col2' : ['value21', 'value22', 'value23'],
    'col3' : ['value31', 'value32', 'value33'],
    'col4' : ['value41', 'value42', 'value43'],
}

it can be converted with

class HTML:

    def __init__(self, Header, tableStyles = {}, trStyles = {}, thStyles = {}):
        self.tableStyles = HTML._styleConverter(tableStyles)
        trStyles = HTML._styleConverter(trStyles)
        thStyles = HTML._styleConverter(thStyles)
        self.rows = []
        self.Header= f'<tr {trStyles} >'
        for th in Header:
            self.Header += f'\n<th {thStyles} >{th}</th>'
        self.Header += '\n</tr>'

    @staticmethod
    def _styleConverter(styleDict : dict):
        if styleDict == {}:
            return ''
        styles = ''
        for [style, value] in styleDict.items():
            styles +=f'{style}: {value};'
        return f'style="{styles}"'

    def addRow(self, row, trStyles = {}, tdStyles = {}):
        trStyles = HTML._styleConverter(trStyles)
        tdStyles = HTML._styleConverter(tdStyles)
        temp_row = f'\n<tr {trStyles} >'
        for td in row:
            temp_row += f'\n<td {tdStyles} >{td}</td>'
        temp_row += '\n</tr>'
        self.rows.append(temp_row)


    def __str__(self):


        return \
f'''
<table {self.tableStyles} >
{self.Header}
{''.join(self.rows)}
</table>
'''



def dictionaryToHTMLTable(dict : dict):
    html = HTML(Header = dict.keys(),
                tableStyles={'margin': '3px'},
                trStyles={'background-color': '#7cc3a97d'},
                thStyles={ 'color': 'white'})
    for i, row in enumerate(zip(*dict.values())):
        print(row)
        if i%2 == 0:
            BGC = 'aliceblue'
        else:
            BGC = '#c2d4e4'
        html.addRow(row, trStyles={'background-color' : BGC}, tdStyles={'padding': '1rem'})
    return html

and to output

print(dictionaryToHTMLTable(myDict))

Answer 6

使用result.iteritems()遍历字典项，然后将键/数据写入 html 表的行中。

#!/usr/bin/env python3

tbl_fmt = '''
<table> {}
</table>'''

row_fmt = '''
  <tr>
    <td>{}</td>
    <td>{}</td>
  </tr>'''


def dict_to_html_table(in_dict):
    return tbl_fmt.format(''.join(row_fmt.format(k, v) for k, v in in_dict.items()))


if __name__ == "__main__":
    d = {key: value for value, key in enumerate("abcdefg")}
    print(d)
    print(dict_to_html_table(d))
