from pathlib import Path
 
filename = Path("source_data/text_files/raw_data.txt")
 
print(filename.name)
# prints "raw_data.txt"
 
print(filename.suffix)
# prints "txt"
 
print(filename.stem)
# prints "raw_data"
 
if not filename.exists():
    print("Oops, file doesn't exist!")
else:
    print("Yay, the file exists!")
