by Allen B. Downey This will be the first edition of Think Python. It uses Python 2, with notes on differences in Python 3. If you're using Python 3, you might need to switch to your second edition.
Example programs and answers to some issues are here links to specific examples come in the book.
Think Python is an breakdown of Python programming for novices. It starts with basic concepts of programming, and is also carefully created to define all terms when they're first used and develop each new idea in a logical progression. Larger pieces, like recursion and object-oriented programming are split up into a sequence of smaller steps and introduced over several chapters.
Some examples and workouts are based on Swampy, a Python package provided by the author to indicate aspects of software design, also to give readers the opportunity to experiment with simple graphics and animation.

PDFMiner can be a tool for extracting information from PDF documents. Unlike other PDF-related tools, it focuses entirely on getting and analyzing text data. PDFMiner allows someone to obtain the location of text in a very page, in addition to other information for instance fonts or lines. It includes a PDF converter which could transform PDF files into other text formats including HTML. It has an extensible PDF parser which could be used in other purposes than text analysis.
Written entirely in Python. for version 2.4 or newer
Parse, analyze, and convert PDF documents.
PDF-1.7 specification support. well, almost
CJK languages and vertical writing scripts support.
Various font types Type1, TrueType, Type3, and CID support.
Basic encryption RC4 support.
PDF to HTML conversion having a sample converter web app.
Tagged contents extraction.
Reconstruct the first layout by grouping text chunks.
PDFMiner is around 20 times slower than other C/C-based counterparts for example XPdf.
In order to process CJK languages, you will need an additional the answer to take during installation:
command, paste the subsequent commands over a command line prompt:
extracts text contents from your PDF file. It extracts every one of the text that happen to be to be rendered programmatically, text represented as ASCII or Unicode strings. It cannot recognize text drawn as images that might require optical character recognition. It also extracts the related locations, font names, font sizes, writing direction horizontal or vertical for every single text portion. You need to give you a password for protected PDF documents when its access is fixed. You cannot extract any text at a PDF document which don't even have extraction permission.
Note: Not all characters inside a PDF may be safely changed to Unicode.
o extract text being an HTML file whose filename is -V - c euc-jp - o extract a Japanese HTML file in vertical writing, CMap is essential -P mypassword - o extract a text from an encrypted PDF file
Specifies the output file name. By default, it prints the extracted contents to stdout in text format.
Specifies the comma-separated list from the page numbers to become extracted. Page numbers start at one. By default, it extracts text from every one of the pages.
Specifies the output codec.
Specifies the output format. The following formats are presently supported.
HTML format. Not recommended for extraction purposes since the markup is messy.
XML format. Provides the most information.
Tagged PDF format. A tagged PDF features its own contents annotated with HTML-like tags. pdf2txt attempts to extract its content streams in lieu of inferring its text locations. Tags used listed here are defined inside the PDF specification See 10.7 Tagged PDF.
Specifies the output directory for image extraction. Currently only JPEG images are supported.
These include the parameters used by layout analysis. In an authentic PDF file, text portions may be split into several chunks within the middle of its running, with respect to the authoring software. Therefore, text extraction should splice text chunks. In the figure below, two text chunks whose distance is closer compared to charmargin shown as M is recognized as continuous and obtain grouped into one. Also, two lines whose distance is closer compared to linemargin L is grouped being a text box, which is really a rectangular area containing a cluster of text portions. Furthermore, it usually is required to insert blank characters spaces as necessary when the distance between two words is greater versus the wordmargin W, to be a blank between words is probably not represented being a space, but indicated by the location of each word.
Each value is specified not as a possible actual length, but to be a proportion on the length on the size of every character under consideration. The default values are M 1.0, L 0.3, and W 0.2, respectively.
Specifies the amount a horizontal and vertical position of an text matters when determining a text order. The value needs to be within the selection of - 1.0 only horizontal position matters to just one.0 only vertical position matters. The default value is 0.5.
Suppress object caching. This will limit the memory consumption but slows down the task.
Suppress layout analysis.
Forces to execute layout analysis for all of the text strings, including text incorporated into figures.
Allows vertical writing detection.
Specifies that this page layout must be preserved. Currently only relates to HTML format.
preserve the actual location of each and every individual character a considerable and messy HTML.
preserve the positioning and line breaks in each text block. Default
preserve the location of every text block.
Specifies the extraction directory of embedded files.
Specifies the output scale. Can be used in HTML format only.
Specifies the absolute maximum number of pages to extract. By default, it extracts each of the pages inside a document.
Provides the consumer password to get into PDF contents.
Increases the debug level.
dumps the inner contents of any PDF file in pseudo-XML format. This program is primarily for debugging purposes, however it is also possible to extract some meaningful contents for example images.
a dump each of the headers and contents, except stream objects -T dump the table of contents -r - i6 extract a JPEG image
Instructs to dump each of the objects. By default, it only prints the document trailer as being a header.
Specifies PDF object IDs to come up with. Comma-separated IDs, or multiple
Specifies the page number to become extracted. Comma-separated page numbers, or multiple
options are accepted. Note that page numbers start at one, not zero.
Specifies the output format of stream contents. Because the belongings in stream objects may be very large, they can be omitted when none from the options above is specified.
option, the raw stream contents are dumped without decompression. With
option, the decompressed contents are dumped being a binary blob. With
option, the decompressed contents are dumped in the text format, similar to
option is offered, no stream header is displayed for that ease of saving it to your file.
Shows the table of contents.
Extracts embedded files on the pdf in to the given directory.
Provides anyone password to get into PDF contents.
Increases the debug level.
