Thanks to all who responded. Now I have so much to think
about. This will probably be my last post on this list; I am not a Perl
programmer and will be looking into Python, Ruby etc lists that I do program
in.
My thoughts on how I like to learn to program:
[1] Playing with the program after skimming through a tutorial.
For instance in python 3.0 it is interesting that
4*'cat'
catcatcatcat
But I found this:
0*'cat'
' '
-5*'cat'
' '
In other words any number<0 0r =0 multiplied by a string gets
the single quotes with nothing between. Can't work out why that is.
[2] Modifying a program that already works. For instance I took
a Ruby calculator program and added the ** exponentiation function to it.
[3] comparing the same idea in different languages such as a
loop.
Perl and Java are very hard to do [1] and [2] with. [3] might
be possible in them. Ruby and Python are easy for doing all 3. Perl might be
a great language. But I have not found it to be beginner friendly for tyros
like me.
