hello,

I am a newbie to python, I have dwelled in c,qt none in java. php a lot,
though I don't make money with any of those.

The best thing I find is python is very easy, the best part maybe
because of my inexperience with other languages are the List and Dict
data types that just solved problems I had in real life made solvable
with python very easily. when I had to worry about memory and pointers
to memory in those other languages, python just made me focus on the
solution I want. also the way I can read python program just like they
are written in plain eglish :)

a personal problem I tried to solve is that how many characters  exist
in  a sequence statistically (with 2 or more characters in len)  in any
given file and then their count.  For a 100kb file I used practially all
programming knowledge in from the other languages but failed miserably
as the computation were taking more time with each bigger chunck of
file. I would have to do a lot of memery management with python using
those style like deleting list and dict before adding another. but when
I tried to solve the problem natively with python it just took a blink
of an eye for them to solve upto 50kb file. but for larger files
although instant it is just memory consuming since I was limit with 2 gb
I ddin't poke further.

this was my exp and I find programming fun in python like ironman
talking to jarvis

keep computing!!!

Nice point!
First class concrete data structures is a blessing especially for
a C programmer.

Here is an old Guido workout of dicts
https://www.python.org/doc/essays/graphs/

Probably can be improved to use comprehensions

Definitely! Worth noting.

There've been some nice concepts mentioned; concrete suggestions would
be good too. Some specific feature or exact line of code that would
show off Python's awesomeness.
