python

- Write a program that decides if an int value obtained from the user is between 0 and 5 inclusive (0 <= value <= 5). Use a Boolean expression to determine if that is the case or not.

- Write a program that checks to see if one integer evenly divides another. Use short circuit logic to evaluate one condition only if another condition is true or false to protect against run-time error.

- Iterating over sequences can be useful when we want to count 'how many' in a collection. To count we can use what is called the Accumulator Pattern. This pattern works by initializing a variable that keeps track of how much has been counted so far. Without using the len() function, how could you count the number of elements in a list using an Accumulator Pattern?

- A commonly used command in Linux is called cat which stands for catenate. It is often used to print the contents of a file to the screen. A similar program can be written in Python. Assuming that the name of a file is in the same directory as your Python program that you are running how would write this code? Do be mindful that there is a ' ' newline character at the end of each line read from the file. Have your code eliminate the extra line. The snippet below will get you started.

filename = input("Please enter the name of a file: ") catfile = open(filename, "r")

The following code does not work. Do you see why? Can you suggest a way to fix it?

def length(alist): len = 1 for i in range(len(alist)): len = len + 1 return len print(length([1,2,3]))
