Python Programming Practice-example programs It is a valuable skill is to be able to read code. In this section we will look in depth at some simple programs and try to understand how they work. Example 1 The following program prints Hello a random number of times between 5 and 25. from random import randint…

Python Programming Practice-SWAPPING Example 1 This program will add up the numbers from 1 to 100. The way this works is that each time we encounter a new number, we add it to our running total, s . s = 0 for i in range (1,101): s = s + i print ( ‘ The…

Python Programming Practice-Miscellaneous Topics I Counting Very often we want our programs to count how many times something happens. For instance, a video game may need to keep track of how many turns a player has used, or a math program may want to count how many numbers have a special property. The key…

If statements Quite often in programs we only want to do something provided something else is true. Python’s if statement is what we need. A Simple Example Let’s try a guess-a-number program. The computer picks a random number, the player tries to guess, and the program tells them if they are correct. To see if…

Numbers This chapter focuses on numbers and simple mathematics in Python. Integers and Decimal Numbers Because of the way computer chips are designed, integers and decimal numbers are represented differently on computers. Decimal numbers are represented by what are called floating point num- bers. The important thing to remember about them is you typically only…

Python Programming Practice: For Loops Introduction For loops are a fundamental control flow structure in Python, allowing you to iterate over sequences such as lists, tuples, strings, or other iterable objects. In this blog post, we will explore several Python programming exercises involving for loops. Each exercise comes with a description, Python code solution, and…

Python Programming Practice-Optional arguments There are two optional arguments to the print function. They are not overly important at this stage of the game, so you can safely skip over this section, but they are useful for making your output look nice. sep Python will insert a space between each of the arguments of the…

Python Programming Practice- TYPING THINGS IN The argument to the print function is the calculation. Python will do the calculation and print out the numerical result. This program may seem too short and simple to be of much use, but there are many websites that have little utilities that do similar conversions, and their code…
