Your task is to write a program or function that takes a string as input, and prints Hello (input), I'm (language name).

Examples

Python:
Input: Oliver
Output: Hello Oliver, I'm Python

C++:
Input: Jacob
Output: Hello Jacob, I'm C++

etc.

Remember, this is , so the code with the lowest number of bytes wins.

Leaderboards

Here is a Stack Snippet to generate both a regular leaderboard and an overview of winners by language.

To make sure that your answer shows up, please start your answer with a headline, using the following Markdown template:

# Language Name, N bytes

where N is the size of your submission. If you improve your score, you can keep old scores in the headline, by striking them through. For instance:

# Ruby, <s>104</s> <s>101</s> 96 bytes

If there you want to include multiple numbers in your header (e.g. because your score is the sum of two files or you want to list interpreter flag penalties separately), make sure that the actual score is the last number in the header:

# Perl, 43 + 2 (-p flag) = 45 bytes

You can also make the language name a link which will then show up in the leaderboard snippet:

# [><>](http://esolangs.org/wiki/Fish), 121 bytes

    \$\begingroup\$ @muddyfish The addition of the input isn't sufficient to distinguish this from the birthday challenge in my opinion. If you want to be picky, this is a half-dupe of cat and a half-dupe of happy birthday. Two half-dupes with a trivial combination makes a whole dupe. \$\endgroup\$ – Mego Sep 25 '16 at 22:59

Python, 29 bytes

"Hello {}, I'm Python".format

Strings methods for the win! The built-in method format of a string substitutes the arguments (here a single string) into any replacement fields (here {}).

Usage:

"Hello {}, I'm Python".format 
print f("xnor")
Hello xnor, I'm Python

Previous 30-byte:

Assembly (x86-64, Linux), 217 205 bytes

4927 segmentation faults later...

.global main
.data
s:.ascii"Hello %qs, I'm Assembly\n"
f:.ascii"%qs"
i:.ascii""
main:mov $i,%rsi
mov $f,%rdi
mov $0,%rax
call scanf
mov $0,%rax
mov $i,%rsi
mov $s,%rdi
call printf
end:mov $0,%rax
call exit

Doesn't work for inputs with a length greater than 7, because this exceeds the memory limits of a quadword(?). Also, because I'm a noob in Assembly.

Explanation:

.global main

.data

output_string: .ascii "Hello %qs, I'm Assembly\n"
format_input: .ascii "%qs"
input_string: .ascii ""

main:
    mov $input_string, %rsi     # Place the memory address to the second argument
    mov $format_input, %rdi     # Place the format string to the first argument
    mov $0, %rax                # Set RAX to 0
    call scanf                  # Call scanf with RDI and RSI as the arguments

    mov $0, %rax                # Set RAX to 0
    mov $input_string, %rsi     # Place the input string to the second argument
    mov $output_string, %rdi    # Place the output format to the first argument
    call printf                 # Call printf with RDI and RSI as the arguments

end:
    mov $0, %rax                # Set RAX to 0 (which is the exit code)
    call exit                   # Call the exit function

Save in a file called myProgram.s and do the following:

$ gcc -o myProgram myProgram.s
$ ./myProgram

Jelly, 16 bytes

“' ṗr>ƊḳȧT°ḋZ»Ỵj

Try it online!

How it works

Call the argument of the main link s.

“' ṗr>ƊḳȧT°ḋZ»

represents an integer in bijective base 256 that encodes a sequence of dictionary words and/or characters. In this specific case, it encodes the dictionary word Hello, followed by ¶, I'm with a leading space ( represents a linefeed), followed by the dictionary word Jelly with a leading space.

The result is as follows.

Hello 
, I'm Jelly

The atoms splits this string at linefeeds, yielding the following array.

["Hello ", "", I'm Jelly"]

Finally, the j atom joins that array, using the string s as separator.

  • \$\begingroup\$ @ConorO'Brien Normally, two words separated by a space are pushed as two separate tokens. For example, 2 3 pushes a 2 and a 3, while 2\ 3 pushes 2 3. There's no special processing to distinguish literal words from literal numbers, they are all represented by scalars in Perl. \$\endgroup\$ – PhiNotPi Sep 27 '16 at 19:00
