I was a Python novice when I first posted this question. Now I know the language very well. Your use case of writing a Python script to download a file from a command line can be covered by utilities like wget or curl. Also, your function downloadFile as posted seems to call itself. Did you intend to indent the second block of code?
In stackoverflow you can correct that by out-denting that. I'd also like to suggest you have a look at Python's argparse library. You can use it to make nice command line utilities. It will take care of the parameters for you. I do like your use of a context manager with open Your code is neatly written.
You are on a good path to learning Python. Good luck! Thanks for the reply, Jim! I've edited the post, and indeed I did not "intend to indent" :D the main part of the program. Thanks for your advices! Nima Sajedi Nima Sajedi 61 6 6 bronze badges. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. BSD License. If none of the Python solutions described here fit your situation, see the section [Other Tools][] for more information. In most cases, you can use the included command-line scripts to extract text and images pdf2txt.
Install it with pip. The package includes the pdf2txt. The command supports many options and is very flexible. Some popular options are shown below. See the usage information for complete details. Note that the package cannot recognize text drawn as images because that would require optical character recognition. It does extract the corresponding locations, font names, font sizes, etc. Often this is good enough—you can extract the text and use typical Python patterns for text processing to get the text or data into a usable form.
The package also includes the dumppdf. This is very useful when you have a problematic PDF and you want to know the exact object IDs that it contains. For example, you might need to know the object ID corresponding to an image in the PDF so you can extract only that image. You run the command with the -a option first so you can review the objects and their IDs, find the object you want images have a SubType of Image , then re-run the command with the -i option to extract only that object.
For example, to extract text from a PDF:. The convert function is called with the name of the PDF file in question, and optionally, a list of pages to process.
By default, all pages are converted to text. The function returns a string containing the text. To retrieve the text extracted from myfile. Note: If you change line 11 to read toc. A typical entry looks like this:. In this example, the URL would look like this:.
How do you know how to piece everything together, what with the manager, the parser, the document, etc.? The documentation for the package is helpful, but in addition, the source code for the command-line commands is straightforward and shows how you can configure your own code. The following example will demonstrate how to use a list in order to select the pages to keep from the original document.
Be aware that the pages that are not specified will not be part of the output document. In our case the output document contains the first, second, and fourth pages only. It provides the methods newPage for adding completely blank pages, and insertPage in order to add an existing page. Table of Contents. Save Article. Improve Article. Like Article.
