file = ctx.web.get_file_by_server_relative_url(file_url)
ctx.load(file)
ctx.execute_query()
print("File Name: ", file.properties['Name'])
Replace "Shared Documents/yourfile.txt" with the appropriate path to your file.
Uploading Files to SharePoint
To upload a new file to SharePoint, follow these instructions:
“`python
file_name = “new_document.txt”
with open(file_name, ‘rb’) as content_file:
file_content = content_file.read()
target_folder_url = “Shared Documents”
ctx.web.lists.get_by_title(target_folder_url).root_folder.upload_file(file_name, file_content).execute_query()
print(“File uploaded successfully.”)
“`
Make sure to change new_document.txt to the file you wish to upload.
Working with SharePoint Lists
Besides handling files, interacting with SharePoint lists can be essential. Here’s how to retrieve items from a SharePoint list:
“`python
