DataFrame students +-------------+--------+ | Column Name | Type | +-------------+--------+ | student_id | int | | name | object | | age | int | | grade | float | +-------------+--------+ Write a solution to correct the errors: The grade column is stored as floats, convert it to integers. The result format is in the following example.

DataFrame students
+-------------+--------+
| Column Name | Type   |
+-------------+--------+

| name        | object |
| age         | int    |
| grade       | float  |
+-------------+--------+

import pandas as pd


def changeDatatype(students: pd.DataFrame) -> pd.DataFrame:
    students['grade'] = students['grade'].astype(int)
    return students
