Question

我正在运行python 3.7的

im，我正在尝试创建一个文件，用作我制作的loginpage.py的运算符，但是当我运行operator.py文件时，它给出了很多错误，但未指定问题指定的一个问题是AttributeError：模块'collections'没有属性'namedtuple'

我尝试在pycharm制作的环境中运行它检查所有语法可能一切看起来不错我尝试在pything 2.2至3.6中运行

from kivy.uix.boxlayout import BoxLayout


class OperatorWindow(BoxLayout):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)


class OperatorApp(App):
    def build(self):
        return OperatorWindow()


if __name__ == "__main__":
    oa = OperatorApp()
    oa.run()

#code ends here

AttributeError: module 'collections' has no attribute 'namedtuple'

从此开始的期望是打开一个名为operator的窗口，该窗口将为空白，但不会打开

我在上面的代码中输入的错误消息

Answer 1

调用模块<table class="table table-bordered table-sm small"> <thead class="thead-dark"> <tr> <th>Jan</th> <th>Feb</th> <th>Mar</th> <th>Apr</th> <th>May</th> <th>Jun</th> <th>Jul</th> <th>Aug</th> <th>Sep</th> <th>Oct</th> <th>Nov</th> <th>Dec</th> </thead> </tr> <?php $html = ""; require 'db.php'; $sqlview="SELECT * FROM booking"; $myData = mysqli_query($con, $sqlview); //loop thru the dates (in your case the SQL results) while($viewrecord = mysqli_fetch_array($myData)){ //get the month number (Jan = 1, Feb = 2 etc.) $monthNumber = date_parse_from_format("y-m-d", $viewrecord['date'])['month']; //return A tr for each result $html .= '<tr>'; //a td for each month for($i = 0; $i < 12; $i++){ $html .= '<td>'; //if column is current month, display date $html .= ($monthNumber === ($i+1)) ? $viewrecord['date'] : ""; $html .= '</td>'; } $html .= '<tr>'; } echo $html; ?> <table>并不是一个好的选择。它在标准库中隐藏了一个模块。

关键困难在于operator 现在将不会启用通常的功能。

考虑将所有内容下推一级，因此您以import operator的身份访问模块而不只是myapp.operator。或者，您可以重命名为operator，或重命名operator1.py目录。

如何解决“集合”模块中找不到“ nametuple”的问题？
