import os

def _delete_files_with_extension(path, extension):
  """Delete all files with a given extension.
  """
  for root, dirs, files in os.walk(path):
    for file in files:
      if file.endswith(extension):
        os.remove(os.path.join(root, file))

# Enter the path
path = "/Users/
Rosey/Desktop/test"

# Enter the extension
extension = ".txt"

# Calling the function
print((_delete_files_with_extension(path, extension)))

#Example Output
