stdin, stdout, stderr

stdouta list of all the words in the input in alphabetical order (one per line). TIP use a dict. Set it up so that if the program gets a command line argument, it expects it to be a file name, and if NOT it reads stdin. You can use the following command to make sure it works right: cat filename python myprog.py

Using Python in labeling and field calculations

Use Python in the Label Expression dialog box 1. Using the information provided, write the sequence of the calculation in nontechnical language, as shown in the following list. Then use this sequence to decide the formal structure of the code. The goal is to use Python string-handling techniques to dress up the labels on this map.

Expects as input a spatial-temporal eld represented a an array (Numpy array or cdms2 variable) of two or more dimensions. Internally, any missing values in the array are identi ed and removed. The EOF solution is computed when an instance of eof2.Eof (for cdms2) or eof2.EofSolver (for Numpy) is initialized.

language. In the case of Python, the concepts of immutability and aliasing play a central role. Call by object reference You can use parameter variables anywhere in the body of the function in the same way as you use local variables. The only difference between a parameter variable and a local variable is that Python initializes

Input is done in Python by using the function input Input has one variable, the prompt, which is a string The result is a string, which might need to get processed by using a type conversion (aka cast) The following prints out the double of the input (provided the user provided input is interpretable as an integer), first

Part (b) [Input]: To make this solution more useful, you will modify it to use the number of widgets input by a user instead of always using 1000. The simplest way to obtain input from a user is with the Python input function on the right side of an assignment statement. The input function takes a single argument, called a prompt, of type str
