about size/resize, and measurements: when assigning width or height, px is often! how many px's are there per inch or per cm? for width, it is convenient, with some other measurements applicable, but for height? px's is rather imperceptible! I tried to attribute a certain height in my code, what is best: px, rows, number of lines or what?

Python provides an inbuilt function 'print' which h automatically generates a line break when it is called, then how can we generate a pattern as : 1 2 2 3 3 3 4 4 4 4 and so on.. using while loop ???

You shall write a program that reads, from standard input, an arbitrary number of case-insensitive card descriptions, the totality of which shall be considered a hand. When standard input is exhausted, the program shall print one line to standard output describing the value of the hand. The program shall generate no other output.

Hmm. But in the case we delete a row (toghether with the ID) there will be a gap between the sequence of the ID's. Does auto_increment fill that gap when a new user is created, or will it just add 1 to the last id in the table?

when adding a pointer in any main body like a inventory displayer , does it matter about the order of placement? Is it necessary to have " return 0;" at the end of it if or is it included with original maroon body? thanks in advance!

When I get to the console application part and put in the project name etc.. once I hit next it does not continue and I basically get a failed message. I assume because I'm using a mac and it does not have a c drive. What's the work around?

CSS The text-indent property I do not understand why you would use this when the </br> tag takes the text back to the left hand side of the page, and as soon as I start a new class the first line of text in a paragraph even with a class it imprints onto every other paragraph like it or not. Why is this please?

Hey there, I don't know why, but when I import tkinter on IDLE like this: from tkinter import * And I say: window = Tk() Even known I use python 3.2.5, which should be able to use Tkinter, the python shell raises a ValueError that says that Tk() is not defined. I am very sure I use python 3.2.5 and tutorials from the Python Foundation say that is what I have to do. But it still doesn't work. Does anyone have an idea of how to solve this problem? Thank you!

Write a program that uses a dynamic array that contains 5 items of double values. The size of the array is entered when the program is run. Aldo the 5 values must be entered. These tasks are done in the main ( ) function. Then write a function to display the 5 values. The function must have a pointer variable as a parameter. The function is called from the main ( ).
