小编Cha*_*hao的帖子

我写了这段代码:

tr = ""
for author, projects in data.iteritems():
    tr + = "<tr><td>{}</td>".format(author)
    for project, branches in projects.iteritems():
        tr += "<td>{}</td>".format(project)
        for branch in branches:
            tr += "<td>{}</td>".format(branch)
    tr += </td></tr>
end = "</table>"

我有这个数据集

{
'user_one': {'project_a': ['branch_1', 'branch_2'],
          'project_b': ['branch_1']},
'user_two': {'project_x': ['branch_x1', 'branch_b'] }
}

我想打印如下表格:

+-------------------------------------------+
|    User    |    Project    |    Branch    |
+------------+---------------+--------------+
|  user_one  |   project_a   |   branch_1   |
+------------+---------------+--------------+
|            |               |   branch_2   |
+------------+---------------+--------------+
|            |   project_b   |   branch_1   |
+------------+---------------+--------------+
