Here is how to check if a text file is empty in Python.

import os 

# Print out 'File is empty!' if nodata.txt is empty
if os.path.getsize('nodata.txt') == 0:
    print("File is empty!") 

---

You can try this yourself below. Try changing 'nodata.txt' to 'data.txt' in line 3 and you will get a different output.
