1 | How To Create PDF (on macOS)
2 | ============================
3 |
4 |
5 | Setup
6 | -----
7 | * Install Adobe Acrobat Pro DC.
8 | * Copy headers and footers from `pdf/acrobat/` folder to `/Users//Library/Preferences/Adobe/Acrobat/DC/HeaderFooter/`.
9 |
10 |
11 | Printing to PDF
12 | ---------------
13 | ### Normal PDF
14 | * Open `index.html` in text editor and first remove element `
` before the `
Libraries
`.
15 | * Then replace the index and footer with contents of `pdf/index_for_pdf.html` file and save.
16 | * Disable internet connection and open Chromium version 108.0.5328.0 (later versions will render the site incorrectly after index is added). Right click anywhere in the window and choose 'inspect'. Go to 'Network' tab and check 'Disable Cache'. Open the `index.html` file while keeping the inspect window open.
17 | * Right click on the border of the site and select inspect. Select `` element under 'Elements' tab and change top margin and top padding from 16 to 0 in 'Styles' tab.
18 | * Change brightness of comments by right clicking on one of them and selecting inspect. Then click on the rectangle that represents color and toggle the color space to HSLA by clicking on the button with two vertical arrows. Change lightness (L) percentage to 77%.
19 | * Change the brightness of text to 13%.
20 | * Select 'Print...' with destination 'Save as PDF', paper size 'A4', 'Default' margins (top 10mm, right 9.5mm, bottom 8mm and left 10mm), 'Default' scale and no headers and footers and save (the document should be 51 pages long with last page empty).
21 | * Check if plots were rendered correctly.
22 |
23 | ### PDF optimized for laser color printing
24 | * Run `./parse.js` again.
25 | * Change all links in text to normal text and add a page number in brackets like that: '(p. )' by running './pdf/remove_links.py' (Links can be found with this regex: `.*a href.*`).
26 | * Open `index.html` in text editor and first remove element `
` before the `
Libraries
`.
27 | * Then replace the index and footer with contents of `pdf/index_for_pdf_print.html` file and save.
28 | * Disable internet connection and open Chromium version 108.0.5328.0 (later versions will render the site incorrectly after index is added). Right click anywhere in the window and choose 'inspect'. Go to 'Network' tab and check 'Disable Cache'. Open the `index.html` file while keeping the inspect window open.
29 | * Right click on the border of the site and select inspect. Select `` element under 'Elements' tab and change top margin and top padding from 16 to 0 in 'Styles' tab.
30 | * Change brightness of elements by right clicking on them and selecting inspect. Then click on the rectangle that represents color and toggle the color space to HSLA by clicking on the button with two vertical arrows.
31 | * Change lightness (L) percentage to:
32 | * 0% for the text.
33 | * 87% for the gray line on the left side of the code.
34 | * 89% for the gray hash characters by the titles
35 | * 37% for the red text and function names (they use their own red).
36 | * 60% for the blue text and the text in the contents (it uses its own blue), but leave color of decorators and the `>>>` intact.
37 | * 58% for the comments.
38 | * Individually change brightness of every comment line that starts with: `# $ pip3 install` and of comments in basic script template to 57%, by adding `color: hsla(0, 0%, 57%, 1);` to their element.style.
39 | * Select 'Print...' with destination 'Save as PDF', paper size 'A4', 'Default' margins (top 10mm, right 9.5mm, bottom 8mm and left 10mm), 'Default' scale and no headers and footers and save (the document should be 51 pages long with last page empty).
40 | * Check if plots were rendered correctly.
41 |
42 |
43 | Adding headers and footers to PDF (the same for both files)
44 | -----------------------------------------------------------
45 | * Open the PDF file in Adobe Acrobat Pro DC.
46 | * Select 'Organize Pages'.
47 | * Right click the second page and select 'Crop Pages...'.
48 | * Select units: 'Inches'.
49 | * In 'Change page size' section select 'A4' for 'Page Sizes' and set 'XOffset' to '0.1 in'. Then click on 'YOffset' input field, so the x offset gets registered. Select page range 'All' and click OK.
50 | * Select 'Edit PDF' tab and add headers and footers by clicking 'Header & Footer' button, selecting a preset from 'Saved Settings' dropdown menu and clicking ok. Popup will say that font 'Menlo' contains invalid encoding. This is fine.
51 | * Start by adding the bottom_line preset and check afterward if bottom line on the first page is aligned properly with the text. If it is not close the file and start over.
52 | * Repeat the process for each preset. When popup asks you if you want to replace existing header or footer click 'Add New'.
53 | * Use this values for font and margins if presets get lost: Borders: left-line: 0.6, left-text: 0.8, top-line: 11.4, bottom-text: 0.27, right-text-odd: 0.57, font-name: menlo, font-size: 8.
54 | * Select 'Organize Pages' tab and remove the last page (it should be empty).
55 | * Select 'File/Properties...' and set title to 'Comprehensive Python Cheatsheet' and author to 'Jure Šorn'.
56 | * Save the progress by running 'Save as' in Format: 'Adobe PDF Files'.
57 | * Run 'Save as' again, this time in 'Adobe PDF Files, Optimized', so that Menlo font error gets fixed.
58 |
59 |
60 | Compressing
61 | -----------
62 | * Compress the two files together with HOW_TO_PRINT.txt instruction file that contains the instructions from the next section using: `zip 'Comprehensive Python Cheatsheet.zip' 'Comprehensive Python Cheatsheet.pdf' 'Comprehensive Python Cheatsheet (optimized for printing).pdf' 'HOW_TO_PRINT.txt'`.
63 |
64 |
65 | Printing the PDF
66 | ----------------
67 | * Open the PDF that was optimized for printing in Chrome and print on A4 on both sides with default margins, scale 98% and no headers and footers.

1 | Which Python version is this for?
2 | Everything should work in the latest Python version, which is 3.12. Every feature that requires version higher than 3.9 has that mentioned in comments or brackets. There are only two such features, both requiring 3.10.
3 | As of 12th March 2024, the only libraries whose latest version requires Python version higher than 3.8 are: numpy, pandas and matplotlib. They all require Python 3.9. This cheatsheet covers numpy version 2.0 (or higher) that was released on 16th June, 2024 and pandas version 2.0 (or higher) that was released on 3rd April 2023.

6 | How to use it?
7 | This cheatsheet consists of minimal text and short examples so things are easy to find with Ctrl+F / ⌘F. If you're on the webpage, searching for '#<name>' will only search for the titles. To get a link to a specific section click the grey hashtag next to the section's title before copying the address. To search for titles in the text editor use ^<name> with enabled regular expressions option.
8 | I also keep the Python console open at all times to test little snippets of code, to check out the available functions of a module using code completion and above all, to use help(<module/object/function/type/str>) command. If something is still unclear, then I search the Python docs by googling 'python docs <module/function>'.
9 | Recently I started using the ptpython REPL (Python console). It supports multiline editing, syntax validation, IDE-like autocompletion and syntax highlighting. It can be installed with pip3 install ptpython. Even more recently I switched to ipython REPL, which is very similar to ptpython only more responsive. It can be installed with pip3 install ipython.

12 | What does the '<type>' signify?
13 | It is a placeholder for an object. It needs to be replaced by an expression, literal or a variable that returns/is of that type. However, if it is located on the left side of an assignment (=) then it signifies what type of object is produced/returned by the expression on the right side of the assignment.

16 | Why the '<type>' semantics?
17 | It makes examples much less ambiguous.

20 | What exactly is <el>?
21 | El is short for element and can be any object, but it usually denotes an object that is an item of a collection.

23 |
24 | What exactly is <collection>?
25 | Collection is my name for an iterable object. An iterable object in Python is any object that has at least one of iter() and getitem() special methods defined. By convention, <object>.__iter__() should return an iterator of object's items and <object>.__getitem__(<index>) an item at that index. I chose not to use the name iterable because it sounds scarier and more vague than collection, even though it has a precise definition.
26 | To make matters a bit more confusing, an abstract base class called Iterable doesn't fully follow this definition. An expression instanceof(<object>, collections.abc.Iterable) only checks whether an object has iter() special method, disregarding the getitem().
