### Methods
#### `login()`
Logs in to Themis. Runs automatically when the class is initialized.

#### `get_year(year_path)`
Returns an instance of a [`Year`](#year) for the academic year specified by `year_path`.

```python
year = themis.get_year(2023, 2024)
```

#### `all_years()`
Returns a list of `Year` instances corresponding to all years visible to the user.

```python
years = themis.all_years()
```

----

## `Year`

### Usage
```python
year = themis.get_year(2023, 2024)
```

### Methods
#### `get_course(course_title)`
Returns an instance of a [`Course`](#course) with the title `course_title`.

```python
pf = year.get_course("Programming Fundamentals (for CS)")
```

#### `get_course_by_tag(course_tag)`
Returns an instance of a [`Course`](#course) using the course identifier `course_tag`.

```python
ai_course = year.get_course_by_tag("adinc-ai")
```

#### `all_courses()`
Returns a list of `Course` instances corresponding to all courses visible to the user in a given `Year`.

```python
courses = year.all_courses()
```

----

## `Course`
### Usage
```python
pf = year.get_course("Programming Fundamentals (for CS)")
assignments = pf.get_groups()
```

### Methods
#### `get_groups(full=False)`
Returns a list of `ExerciseGroup` or `Group` instances corresponding to all items visible to the user in a given `Course`. The default argument is `full=False`, which will only return the top-level (name, link) of each item. If `full=True`, it will traverse the whole course.

```python
ai_groups = ai_course.get_groups(full=True)
exercise = ai_groups[7].exercises[1]
exercise.submit(["solution.py"], silent=False)
```

#### `get_group(name, full=False)`
Returns an instance of an `ExerciseGroup` or `Group` with the name `name`. The default argument is `full=False`, which will only return the (name, link) of the group. If `full=True`, it will traverse the whole group.

```python
week1 = pf.get_group("Week 1")
```

#### `create_group(item_data)`
Creates and returns a `Group` or `ExerciseGroup` instance based on `item_data`.

```python
group = course.create_group(item_data)
```

----

## `Group`

Represents an item in Themis, which can be either a folder (non-submittable) or an assignment (submittable).

### Methods
#### `get_items()`
Returns all items (groups and assignments) under this group.

```python
items = week1.get_items()
```

#### `get_item_by_title(title)`
Returns a single item by its title (case-insensitive).

```python
item = week1.get_item_by_title("Exercise 2")
```

#### `get_status(text=False)`
Retrieves the status of the group. When `text=True`, returns the status as strings. Otherwise, returns submission objects or strings.

```python
status = group.get_status()
leading_submission = status["leading"]
```

#### `download_files(path=".")`
Downloads all files available for this group to a directory `path`. Defaults to the current directory.

```python
group.download_files()
```

#### `download_tcs(path=".")`
Downloads all test cases for this group to a directory `path`. Defaults to the current directory.

```python
group.download_tcs()
```

#### `submit(files, judge=True, wait=True, silent=True)`
Submits the files to the group. Default arguments are `judge=True`, `wait=True`, and `silent=True`.

```python
group.submit(["solution.py"], silent=False)

#### `get_info()`
Returns detailed information about the submission.

```python
info = submission.get_info()
