Defining if a parquet file exists in a Notebook

All

I need to check if a parquet file exists before running some code.  Is there a way of checking if a file exists in a notebook.  I just need it to return a true or false.

 

Thanks

 

Neil

Thanks for this, but they didn't work as I needed to use wildcards in my pathway.  However this worked

 

Import glob

 

search_pattern = '/root_folder/*/*/*/target_file.txt'

 

files = glob.glob(search_pattern)
if files:
    print(f"File found: {files[0]}")
else:
    print("File not found.")
