- This contains the text 'It works!' Referred to in the post. What I did was duplicate that file in the same folder and changed the duplicate's name to 'index.html', leaving the original in situ. Both local and user sites then loaded. After which, I was able to delete the duplicated file and everything now works without issue.
- Create an HTML file. In the TextEdit app on your Mac, choose File New, then choose Format Make Plain Text. Enter the HTML code. Choose File Save, type a name followed by the extension.html (for example, enter index.html), then click Save. When prompted about the extension to use, click “Use.html.”.

Lesson Goals
This lesson uses Python to create and view an HTML file. If you writeprograms that output HTML, you can use any browser to look at yourresults. This is especially convenient if your program is automaticallycreating hyperlinks or graphic entities like charts and diagrams.
Here you will learn how to create HTML files with Python scripts, andhow to use Python to automatically open an HTML file in Firefox.
Files Needed For This Lesson

If you do not have these files from the previous lesson, you candownload programming-historian-5, a zip file from the previous lesson.
Creating HTML with Python
At this point, we’ve started to learn how to use Python to downloadonline sources and extract information from them automatically. Rememberthat our ultimate goal is to incorporate programming seamlessly into ourresearch practice. In keeping with this goal, in this lesson and thenext, we will learn how to output data back as HTML. This has a fewadvantages. First, by storing the information on our hard drive as anHTML file we can open it with Firefox and use Zotero to index andannotate it later. Second, there are a wide range of visualizationoptions for HTML which we can draw on later.
If you have not done the W3 Schools HTML tutorial yet, take a fewminutes to do it before continuing. We’re going to be creating an HTMLdocument using Python, so you will have to know what an HTML documentis!
“Hello World” in HTML using Python
One of the more powerful ideas in computer science is that a file thatseems to contain code from one perspective can be seen as data fromanother. It is possible, in other words, to write programs thatmanipulate other programs. What we’re going to do next is create an HTMLfile that says “Hello World!” using Python. We will do this by storingHTML tags in a multiline Python string and saving the contents to a newfile. This file will be saved with an .html extension rather than a.txt extension.
Typically an HTML file begins with a doctype declaration. You sawthis when you wrote an HTML “Hello World” program in an earlier lesson.To make reading our code easier, we will omit the doctype in thisexample. Recall a multi-line string is created by enclosing the text inthree quotation marks (see below).
Save the above program as write-html.py and execute it. Use File ->Open in your chosen text editor to open helloworld.html to verify thatyour program actually created the file. The content should look likethis:
Now go to your Firefox browser and choose File -> New Tab, go to thetab, and choose File -> Open File. Select helloworld.html. Youshould now be able to see your message in the browser. Take a moment tothink about this: you now have the ability to write a program which canautomatically create a webpage. There is no reason why you could notwrite a program to automatically create a whole website if you wantedto.
Using Python to Control Firefox
We automatically created an HTML file, but then we had to leave oureditor and go to Firefox to open the file in a new tab. Wouldn’t it becool to have our Python program include that final step? Type or copythe code below and save it as write-html-2.py. When you execute it, itshould create your HTML file and then automatically open it in a new tabin Firefox. Sweet!
Mac Instructions
Mac users will have to specify to the precise location of the .htmlfile on their computer. To do this, locate the programming-historianfolder you created to do these tutorials, right-click it and select “GetInfo”.
You can then cut and paste the file location listed after “Where:” andmake sure you include a trailing slash (/) to let the computer know youwant something inside the directory (rather than the directory itself).
If you’re getting a “File not found” error you haven’t changed thefilename path correctly.

Windows Instructions
***
Not only have you written a Python program that can write simple HTML,but you’ve now controlled your Firefox browser using Python. In the nextlesson, we turn to outputting the data that we have collected as an HTMLfile.

Code Syncing
To follow along with future lessons it is important that you have theright files and programs in your “programming-historian” directory. Atthe end of each lesson in the series you can download the “programming-historian” zipfile to make sure you have the correct code. If you are following alongwith the Mac / Linux version you may have to open the obo.py file andchange “file:///Users/username/Desktop/programming-historian/” to thepath to the directory on your own computer.

So I created an html page with TextEdit on my mac saving it at an HTML file, however when I click on it, to open it with safari, the all coding appears on my web page:
<!DOCTYPE html><html> <head> <meta charset='utf-8'> <title> My page </title> </head> <body> <p> Lorem blabla </p> </body></html>
Normally i should be able to only see the title My page and Lorem blabla.
But it's not the case at all (you can check out what i see by copy pasting this: file:///Users/paulinefaure/Desktop/Index%20copy.html
What should I do?
I Know why!
you need to convert your file on text edit, to simple instead of rich text. You do this by going to format, and looking for the simple text format, and select it. Then when you save the file, next to what ever name you use for it put .htmland de-selecting the option that says that it'll automatically be a txt file if nothing else is selected.
Then if you want to view it on you web page, go to your file and select open with, and select whatever browser you use. Then you can just edit your code at will and save it and refresh your page in order to view what it looks like.
Hi Pauline,
Open Html File On Mac
Make sure you have closed all of your HTML tags. If you need help, you can use Markdown here to display your code and we can help review it. (Use the 3 backticks around your code to display it inline as code, as the Markdown Cheatsheet shows.)
We won't be able to see what you see with your link. That link indicates a file stored locally on your computer.
Hi Pauline,
TextEdit is a word processor and needs to be configured to work with text files.
I would recommend that you switch to a text editor like sublime text or do a search for 'mac text editor' for more options.
How To Open Html File On Mac

Hi Pauline,Unfortunately, I can't see your HTML file as it's local to your machine and not on a public web server. I noticed that you are using Text Edit on a Mac. I use this from time to time as well! My best and initial guess stems from this answer I came across on stack overflow. (http://stackoverflow.com/questions/6758706/why-isnt-html-rendering-on-my-web-browser) It would be a good idea to make sure that you are producing your files in 'Plain Text'. To check this in Text Edit, click Text Edit in the top menu bar and then Preferences. Click the 'Plain Text' radio button and then create your file.
I hope this helps!Brenton
To correct some previous responses: You can open local HTML files in Safari and they should be interpreted and displayed correctly.
Edit Html File On Mac
As some other users advised, I also would recommend you to use a text editor primarily developed for editing code.When using TextEdit there are two ways to write your markup properly:
- Under TextEdit > Preferences: New Document: Format select the radio 'Plain Text'. Then create a new document.
- Simply create a new document regardless of your preferences. After that click Format > Convert to plain text (or simply hit
[cmd]+[shift]+[t]).
Can You Do Html On A Mac
Write your code into the newly created file (plain text) and save it with the file extension '.html'.You can open this file in Safari or any other web browser properly.
Actually, to see the website you will need to host it online because its saved locally on your mac. Can you post whats inside of your html file here to see exactly whats wrong? Also make sure you save your file as name_of_file.html
