A good tutorial for beginners is at:
http://www.byteofpython.info/
Also read through the Starting Python "sticky" and the Python code snippets here on DaniWeb. Above everything, run the code and experiment with it! Change it a little at first and then get braver!
I have bought a number of Python books, but don't think much of them. They are often outdated, poorly organized and indexed, also have quite a few mistakes in the code. Get books used, if possible!
Python is much easier to learn and understand than C or C++. Much of Python (eg. Python24.dll) is written in C and/or C++, but you don't have to be concerned with that.
Research has been published that claims that Python is about 10 times faster for developing a program than C++ or Java. They are talking about rather large and complex client requested programs. Both Google and Yahoo rely heavily on Python.
A typical example of Python code is ...
# print out a given year's monthly calendar
import calendar
# if you want September 2005 use ...
calendar.prmonth(2005, 9)
... try to do this with C++
