# Task Implement **`solution.py`** with `parse_int_list(text: str) -> list[int]`: parse a string containing a JSON array of integers (e.g. `"[1, 2, 3]"`) into a Python list of ints.
Proposed solution
```python
import json
def parse_int_list(text: str) -> list[int]:
"""
Parse a string containing a JSON array of integers into a Python list of ints.
Args:
text (str): A string representing a JSON array of integers, e.g., "[1, 2, 3]"
Returns:
list[int]: A Python list containing the integers from the JSON array
Raises:
json.JSONDecodeError: If the input string is not valid JSON
TypeError: If the parsed JSON is not a list
ValueError: If any element in the list is not an integer
"""
try:
parsed = json.loads(text)
# Verify that the parsed result is a list
if not isinstance(parsed, list):
raise TypeError("Input must be a JSON array")
# Verify all elements are integers and convert them to Python int
result = []
for item in parsed:
if not isinstance(item, int) or isinstance(item, bool):
raise ValueError(f"All elements must be integers, got {type(item).__name__}")
result.append(item)
return result
except json.JSONDecodeError as e:
raise e
