[Question]
  [
***This contest is officially over, the winner is [jimmy23013](https://codegolf.stackexchange.com/users/25180/user23013). Congratulations!***
The challenge is to make a program that prints `Hello World!` to stdout. The catch is that your program must have a [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance) of 7 or less from the program in the answer submitted before yours.
# How This Will Work
Below I have already submitted the first answer using Python: `print("Hello World!")`.
The next person to answer must modify the string `print("Hello World!")` with up to 7 single character insertions, deletions, or substitutions so that when it is run in any language that hasn't been used so far (only Python in this case) the output is still `Hello World!`.
For example the second answerer might use 1 substitution (`r -> u`), 2 deletions (`in`), and 1 insertion (`s`) to make the string `puts("Hello World!")` which prints `Hello World!` when run in Ruby.
The third person to answer must do the same thing in a new language, but using the program of the second person's answer (e.g. `puts("Hello World!")`) as their starting point. The fourth answer will be in relation to the third answer and so on.
This will continue on until everyone get stuck because there is no new language the last answer's program can be made to run in by only changing 7 characters. The communal goal is to see how long we can keep this up, so try not to make any obscure or unwarranted character edits (this is not a requirement however).
# Formatting
Please format your post like this:
```
# Answer N - [language]
    [code]
[notes, explanation, observations, whatever]
```
Where N is the answer number (increases incrementally, N = 1, 2, 3,...).
You do not have to tell which exact characters were changed. [Just make sure the Levenshtein distance is from 0 to 7.](http://planetcalc.com/1721/)
# Rules
The key thing to understand about this challenge is that **only one person can answer at a time and each answer depends on the one before it**.
There should never be two answers with the same N. If two people happen to simultaneously answer for some N, the one who answered later (even if it's a few seconds difference) should graciously delete their answer.
Furthermore...
* **A user may only submit one answer per 8 hour period.** i.e. Each of your answers must be at least 8 hours apart. (This is to prevent users from constantly watching the question and answering as much as possible.)
* A user may not submit two answers in a row. (e.g. since I submitted answer 1 I can't do answer 2, but I could do 3.)
* Each answer must be in a different programming language.
	+ Different versions of the same language count as the same language.
	+ Languages count as distinct if they are traditionally called by two different names. (There may be some ambiguities here but don't let that ruin the contest.)
* You may only use tabs, newlines, and [printable ASCII](http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters). (Newlines count as one character.)
* The output should only be `Hello World!` and no other characters (a leading/trailing newline is not an issue).
* If your language doesn't has stdout use whatever is commonly used for quickly outputting text (e.g. `console.log` or `alert` in JavaScript).
**Please make sure your answer is valid.** We don't want to realize there's a break in the chain five answers up. Invalid answers should be fixed quickly or deleted before there are additional answers.
**Don't edit answers unless absolutely necessary.**
# Scoring
Once things settle down, the user who submits the most (valid) answers wins. Ties go to the user with the most cumulative up-votes.

This question works best when you [sort by oldest](//codegolf.stackexchange.com/questions/40376/evolution-of-hello-world-testing-new-type-of-challenge?answertab=oldest#tab-top).
*NOTE: This is a trial question for a new challenge type I have in mind where each answer depends on the last and increases in difficulty.

# Answer 1 - Python

There's got to be dozens of languages this could morph into.

## Answer 59 - HTML
**What? No HTML ??**
```
<echo o[.]c;cat<<;#&&alert" ">Hello World!</vsh
```
Distance from [Answer 58](https://codegolf.stackexchange.com/a/40474/31414) : 6
**Voodoo Magic ? Nah. Here is how it works:**
You can have any arbitrary tag in HTML, so the first part `<echo o[.]c;cat<<;#&&alert" ">` is an `echo` tag, which now becomes a blank tag with no CSS applied by default by the browser.
The `o[.]c;cat<<;#&&alert" "` part is actually two properties set on that tag separated by space. So the first property has the key `o[.]c;cat<<;#&&alert"` and second key is `"` and both the values are blank.
Second part is just plain text `Hello World!` which is the text contents of the `echo` tag.
Next up, HTML tries to find the closing `echo` tag, but instead, finds a closing `vsh` tag. It then ignores the closing `vsh` tag (i.e. `</vsh`) and auto closes the `echo` tag.

# Answer 85 - [GDB](http://www.gnu.org/software/gdb/) (GNU Debugger)
```
#[]([.]c;main()&alert"  "
    echo Hello World!
#[;]:;#bye;dnl</vsh>
```
I think this can also be qualified as a programming language. It has even [`if` and `while` commands](https://sourceware.org/gdb/current/onlinedocs/gdb/Command-Files.html#Command-Files).
[`echo`](https://sourceware.org/gdb/current/onlinedocs/gdb/Output.html) is another built in command in GDB.
To run this code:
```
gdb --batch -x file
```

```
**Voodoo magic ?? Nah!! Here is how it works:**
* `[text](link)` creates a link.
So the first part of the code is
```
[](#[.]c;cat;#&&alert"  "
        @echo)
```
Which creates an empty text link with location
```
#[.]c;cat;#&&alert"  "
     @echo
```
* Next part `Hello World!` is printed as is
* Then `[;]:;#bye;dnl</vsh>` creates a reference link for `;` which can be used anywhere in the markdown.
Ex:
```
[Some text][;] // Outputs a link with text "Some text" and url ";#bye;dnl</vsh>"
```

I think this works, an interpreter is [here (Kona)](https://github.com/kevinlawler/kona). `/` begins a one-line comment in K. I've cleaned up some of the `#]trace=:(` mess.
