如果在使用Pywin32库中的win32print模块时出现了`"win32print" is not defined`的错误,可能是因为没有正确导入这个模块。
在导入Pywin32库时,应该使用`import win32print`语句来导入win32print模块,这样才能在代码中使用该模块提供的函数和类。
如果你已经正确导入了win32print模块,但是仍然出现该错误,可能是因为在代码中使用了未定义的变量名或没有正确安装Pywin32库。你可以尝试检查代码中的变量名拼写是否正确,或者重新安装Pywin32库来解决问题。

$(...).fullCalendar is not a function
This error message typically indicates that the FullCalendar library has not been properly loaded in your project.
Make sure that you have included the FullCalendar library in your HTML file, and that it is being loaded before any JavaScript code that references it.
Here's an example of how to include the FullCalendar library in your HTML file:
```
<head>
<link href='https://cdnjs.cloudflare.com/ajax/libs/fullcalendar/3.10.2/fullcalendar.min.css' rel='stylesheet' />
<link href='https://cdnjs.cloudflare.com/ajax/libs/fullcalendar/3.10.2/fullcalendar.print.min.css' rel='stylesheet' media='print' />
<script src='https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js'></script>
<script src='https://cdnjs.cloudflare.com/ajax/libs/fullcalendar/3.10.2/fullcalendar.min.js'></script>
</head>
```
If you're still encountering the error message after checking that the library is properly loaded, make sure you're using the correct syntax to call the `.fullCalendar` function.
For example, if you're using FullCalendar version 3, the syntax would be:
```
$('#calendar').fullCalendar({
// options and callbacks
});
```
If you're using a different version of FullCalendar, make sure to check the documentation for the correct syntax.
def good_function(x = 0.0): print(x) x = np.random.randn() why this function do not have return but could still run
This function `good_function` will run without any error even though it does not have a return statement because it does not require any output to be returned.
The function takes an optional argument `x` with a default value of 0.0. When the function is called, it prints the value of `x` and then assigns a random number generated using the NumPy library to `x`.
Since there is no return statement, the function does not return any value, but it does successfully print the value of `x` and update its value.
However, if you try to use the value of `x` after calling the function, it will be the updated random number generated by NumPy and not the original value passed to the function.
