CAL | Conditional Affordance Learning

It has to do with CoroutineScopes and children of coroutines. When a parent coroutine is canceled, all its children are canceled as well.

What I've done here is remove the borders from the table and collapsed the space for them.

I've then used more semantic elements for both table headings and your actual content with semantic class names. This included adding a new element for the elements you want at the bottom of the cell. Finally, the teacher and codes are floated left and right respectively.

I am not much familiar with Jinja, so this answer might not be the most efficient one.

By using basic hard coding in your Template.HTML file, I was able to achieve the results you are trying to. For this, I used the same code that was given by D-E-N in your previous question.

I combined all the attributes of your object into a string

• An attribute is differentiated from another with @ (like Course and Teacher)
• Instead of using space character, I used a _ character to represent space character in the attributes.
• If one slot contains multiple objects, they are differentiated with space character (just like in the code provided by D-E-N)

Here's the updated code of yours with these changes,

The problem here is that rules is a class attribute (a list of objects). See the code taken from here:

This is what you want. I first test the last character of the input string with a regex detecting special characters, and if there is a special character inside the input and if the value of the button you pressed is a also a special character, I delete the last character from the string. And then at the end the value of the button you pressed is appended to the end of the string.

The problem is happening because you're trying to reference a variable that's local to one method of one page on another. In an app with this architecture, a good way to share data among the Page class instances is through the controller argument they are all passed when they're created, which in this case is the StudyFriendO class instance.

Since you may have more than one variable to share as you develop your app, I've added a shared_data dictionary attribute and initialized with a tk.StringVar associated with the key 'name'. It is used as the textvariable= option when creating the tk.Entry widget on the StartPage and then also by the getname() method of the StudyFriendO controller. Using a StringVar allows the dictionary item to be defined before the Entry widget using it is created. After that happens (i.e. the StartPage instance is created) the current value of the Entry can be retrieved indirectly through it instead of the widget itself in the getname() method. You can easily add more variables in the future should you need them.

Below is your code with the modifications described. I've indicated where the changes are with #### comments to make them standout.

That depends on the paper you want to download.

I modified a bit the function you posted. Now it gets the response as JSON and no XML (this is just my personal preference, you can use the format you prefer).

ISO 8601 does permit this year format. From Wikipedia:

To represent years before 0000 or after 9999, the standard also permits the expansion of the year representation but only by prior agreement between the sender and the receiver. An expanded year representation [±YYYYY] must have an agreed-upon number of extra year digits beyond the four-digit minimum, and it must be prefixed with a + or − sign instead of the more common AD/BC (or CE/BCE) notation;

However, since it only permits this "by prior agreement between the sender and the receiver", it is quite strange that adding the sign is the default behaviour of LocalDate.toString.

According to the docs:

Year: The count of letters determines the minimum field width below which padding is used. If the count of letters is two, then a reduced two digit form is used. For printing, this outputs the rightmost two digits. For parsing, this will parse using the base value of 2000, resulting in a year within the range 2000 to 2099 inclusive. If the count of letters is less than four (but not two), then the sign is only output for negative years as per SignStyle.NORMAL. Otherwise, the sign is output if the pad width is exceeded, as per SignStyle.EXCEEDS_PAD.

So if you don't want the sign, you can use 3 "y"s, or just 1 "y", since 3 and 1 are both "less than four (but not two)".

Also, since "y" means "year of era", there won't be any negative years, so you don't need to worry about it outputting a sign for negative years either.

Example:

First you need to join both dataframes using full method to keep unmatched rows (new) and to updating the matched records I do prefer to use select with coalesce function:
