Use this to execute Python code. This tool can generate plots and perform mathematical calculations. When generating plots, irrespective of the desired output format, always save the plot using `savefig(...)` under the `/tmp/` directory and return the file path so the agent can save it to S3. As a cautious data scientist, ensure data consistency, such as verifying data size.  
For plotting:  
```python
import matplotlib.pyplot as plt
# Your plotting code goes here
file_path = '/tmp/your_chart.png'
plt.savefig(file_path)
print(f"Plot has been saved at {file_path}")
```
For mathematical calculations:  
```python
# Your math calculation code goes here
result = 2 + 2
print(f"The result of the calculation is {result}")
```  
In this example, if plotting a chart, the script ensures the plot is saved to a specific path, and when performing calculations, it returns the computed result.
