What does %c character formatting do in Python and it's use?

Going through string formatting operations but can't exactly wrap my head about %c operation and its use.

Learn Python the Hard Way, gave the following example but it makes little sense without the proper context.

"%c" % 34 == '"'

Here is the link to if anyone wants to check it out: http://learnpythonthehardway.org/book/ex37.html

The %c is a format character gives the character representation. For example consider the following statements

>>> print "%c" % 'a'
a
>>> print ("%c" % 97)
a
>>> print "%c" %'"'
"
>>> print "%c" %34
"
>>> print "%c" %'asdf'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: %c requires int or char

Breaking up

"%c" % 34 == '"'

would be like

>>> "%c" % 34
"
>> '"' == '"'
True

%c represents character values. It's part of the integer representation types.

You can't enter a value larger than an unsigned byte (255) as a positional argument to it, so be careful where and when you elect to use it.

It gives the character that is represented by the ASCII code "34".

If you look up an ASCII table you will notice that 34 = "
