# two_char





Given a string and an index, return a string length 2 starting at the given index. If the index is too big or too small to define a string length 2, use the first 2 chars. The string length will be at least 2.

```
two_char("java", 0) -> "ja"
two_char("java", 2) -> "va"
two_char("java", 3) -> "ja"
```

This exercise was taken from [codingbat.com](https://codingbat.com/prob/p144623) and has been adapted for the Python language. There are many great programming exercises there, but the majority are created for Java.

## Starter Code
```python
def two_char(string: str, index: int) -> str:
    pass


result = two_char('java', 0)
print(result)
```

## Tests
```python
from main import two_char


def test_two_char_1():
    assert two_char('java', 0) == 'ja'


def test_two_char_2():
    assert two_char('java', 2) == 'va'


def test_two_char_3():
    assert two_char('java', 3) == 'ja'


def test_two_char_4():
    assert two_char('java', 4) == 'ja'


def test_two_char_5():
    assert two_char('java', -1) == 'ja'


def test_two_char_6():
    assert two_char('Hello', 0) == 'He'


def test_two_char_7():
    assert two_char('Hello', 1) == 'el'


def test_two_char_8():
    assert two_char('Hello', 99) == 'He'


def test_two_char_9():
    assert two_char('Hello', 3) == 'lo'


def test_two_char_10():
    assert two_char('Hello', 4) == 'He'


def test_two_char_11():
    assert two_char('Hello', 5) == 'He'


def test_two_char_12():
    assert two_char('Hello', -7) == 'He'


def test_two_char_13():
    assert two_char('Hello', 6) == 'He'


def test_two_char_14():
    assert two_char('Hello', -1) == 'He'


def test_two_char_15():
    assert two_char('yay', 0) == 'ya'
