# Check if a word is correct

To check if a word is correct, you need to use the `is_correct` method of the `Proofreader` class. This method takes a word as an argument and returns a boolean value indicating whether the word is spelled correctly or not.

For example, suppose you have created an instance of the `Proofreader` class called `pr`:

```python
pr = Proofreader()
```

Then, you can check if a word is correct by calling the `is_correct` method on `pr` and passing the word as an argument:

```python
pr.is_correct("hello") # returns True
pr.is_correct("helo") # returns False
```

The `is_correct` method compares the word with the words in the wordlist file. If the word is found in the wordlist file, it returns True. Otherwise, it returns False.

You can also check multiple words at once by using a loop or a list comprehension:

```python
words = ["hello", "helo", "world", "wrold"]
[pr.is_correct(word) for word in words] # returns [True, False, True, False]
```

The `is_correct` method is case-insensitive, which means that it does not matter if the word is in uppercase, lowercase, or mixed case. The method will convert the word to lowercase before comparing it with the words in the wordlist file. For example:

{% code fullWidth="false" %}

```python
pr.is_correct("Hello") # returns True
pr.is_correct("HELLO") # returns True
pr.is_correct("HeLlO") # returns True
```

{% endcode %}

All of these words are considered correct, because they are the same as “hello” in lowercase.
