| - | As a final task, we want to upload some files using our web application. | + | First, take a couple (3-4) of paragraphs [[https://www.gutenberg.org/files/2701/2701-h/2701-h.htm#link2HCH0001|from here]] and store them inside a ''.txt'' file. |
| - | + | ||
| - | * Create a new ''upload.html'' form page with a ''<input type=file ...>'' field (and, ofc., a submit button!); | + | |
| - | * Note: you need to use ''multipart/form-data'' form encoding for HTTP file uploading to work. | + | |
| - | * Create the appropriate Flask route that serves the ''upload.html'' page; | + | |
| - | * Check Flask's [[https://flask.palletsprojects.com/en/2.1.x/api/#incoming-request-data|''Request'' object reference]] for accessing the uploaded files; | + | |
| - | * Enhance your route function to save the uploaded file on disk (e.g., the ''upload/'' directory); | + | |
| - | * Finally, test it! | + | |
| + | * Open the file and read its contents into string; | ||
| + | * Build a ''dict'' with each word from this text (lower cased as key), counting their frequency (as its value); | ||
| + | * Use it to print out the most frequent 5 words in this text (together with their value!), e.g.: | ||
| + | <code> | ||
| + | [('the', 29), ('of', 18), ('and', 15), ('to', 10), ('a', 9)] | ||
| + | </code> | ||
