Syntax Highlighting: List of Supported Languages at Qiita --Qiita Wright's memorandum.
Probably Qiita's syntax highlighting engine is Pygments.
The usage and examples of each item are shown.

bash
An example of spamhaus.sh from cowgill / spamhaus.
spamhaus.sh
#!/bin/bash
# based off the following two scripts
# http://www.theunsupported.com/2012/07/block-malicious-ip-addresses/
# http://www.cyberciti.biz/tips/block-spamming-scanning-with-iptables.html
# path to iptables
IPTABLES="/sbin/iptables";
# list of known spammers
URL="www.spamhaus.org/drop/drop.lasso";
# save local copy here
FILE="/tmp/drop.lasso";
# iptables custom chain
CHAIN="Spamhaus";
# check to see if the chain already exists
$IPTABLES -L $CHAIN -n
# check to see if the chain already exists
if [ $? -eq 0 ]; then
# flush the old rules
$IPTABLES -F $CHAIN
echo "Flushed old rules. Applying updated Spamhaus list...."
else
# create a new chain set
$IPTABLES -N $CHAIN
# tie chain to input rules so it runs
$IPTABLES -A INPUT -j $CHAIN
# don't allow this traffic through
$IPTABLES -A FORWARD -j $CHAIN
echo "Chain not detected. Creating new chain and adding Spamhaus list...."
fi;
# get a copy of the spam list
wget -qc $URL -O $FILE
# iterate through all known spamming hosts
for IP in $( cat $FILE | egrep -v '^;' | awk '{ print $1}' ); do
# add the ip address log rule to the chain
$IPTABLES -A $CHAIN -p 0 -s $IP -j LOG --log-prefix "[SPAMHAUS BLOCK]" -m limit --limit 3/min --limit-burst 10
# add the ip address to the chain
$IPTABLES -A $CHAIN -p 0 -s $IP -j DROP
echo $IP
done
echo "Done!"
# remove the spam list
unlink $FILE
python, py, python3, py3
This is the python source as it is. The display is slightly different between python and python3.

pycon
Probably for console output when python is started on the console like ↓.
# python
Python 2.5.2 (r252:60911, Jan 24 2010, 14:53:14)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>
From http://docs.python.jp/2/library/random.html An example of python console output modified with pycon.
pycon
>>> random.random() # Random float x, 0.0 <= x < 1.0
0.37444887175646646
>>> random.uniform(1, 10) # Random float x, 1.0 <= x < 10.0
1.1800146073117523
>>> random.randint(1, 10) # Integer from 1 to 10, endpoints included
7
>>> random.randrange(0, 101, 2) # Even integer from 0 to 100
26
>>> random.choice('abcdefghij') # Choose a random element
'c'
>>> items = [1, 2, 3, 4, 5, 6, 7]
>>> random.shuffle(items)
>>> items
[7, 3, 2, 5, 6, 4, 1]
>>> random.sample([1, 2, 3, 4, 5], 3) # Choose 3 elements
[4, 1, 5]
pytb/py3tb
For stack trace output by python.
In the example below, no difference between pytb and py3tb was visible.
pytb
Traceback (most recent call last):
File "<doctest...>", line 10, in <module>
lumberjack()
File "<doctest...>", line 4, in lumberjack
bright_side_of_death()
IndexError: tuple index out of range
py3tb
Traceback (most recent call last):
File "<doctest...>", line 10, in <module>
lumberjack()
File "<doctest...>", line 4, in lumberjack
bright_side_of_death()

sql For SQL queries.

JSON Although not on the list, syntax highlighting is also valid for JSON.
JSON

"value" : 100,
"list" : ["a", "b", "c"],
