<td width="20%"><b>Introduction</b></td>

This programming assignment is designed to show how Python functions can define

other Python code (in this case, a class) in an unexpected way: the function

can build a huge string that represents the definition of a Python class and

then call <b>exec</b> on it, which causes Python to define that class just as

if it were written in a file and imported (in which case Python reads the

file as a big string and does the same thing).

Your code will heavily rely on string formatting operations: I suggest using

the <b>str.format</b> method to do the replacements: now is a good time to

learn about this function if you don't know already know it; but you are free

to use whatever string processing tool(s) you want.

<p>

I suggest that you first read the description below and define/test/debug as

much of the <b>Point</b> class as you can, writing it directly in Eclipse

(especially the<b>__getitem__</b>, <b>__eq__</b>, and <b>_replace__</b>

methods).

You might want to write a small batch file to help you test this class.

</p><p>

Once you have written/debugged the code for the <b>Point</b> class, define the

general <b>pnamedtuple</b> function, which when given the appropriate

arguments (for the <b>Point</b> class: <b>pnamedtuple('Point', 'x y')</b>)

constructs a huge string containing the same code as the <b>Point</b> class

you wrote.

Much of the code from your <b>Point</b> class will be turned into strings and

made generic: generalized for calls to <b>pnamedtuple</b> with different

arguments.

Use the <b>.format</b> method to replace the generic parts with the actual

strings needed for the class being defined.

return 1;

}

/* read s1 s2 from the file */

s1=fgets(s1, MAX, fp);

s2=fgets(s2, MAX, fp);
