+# to test the DataInterpreter's issue solving ability.

+# Requirement
+Below is a github issue, solve it. Use FileManager to search for the function, understand it, and modify the relevant code.
+Write a new test file test.py with FileManager and use Terminal to python the test file to ensure you have fixed the issue.
+When writing test.py, you should import the function from the file you modified and test it with the given input.
+Notice: Don't write all codes in one response, each time, just write code for one step.
