Re: Projects for the Beginner

Click to Expand / Collapse  Quote originally posted by XxAaronxX ...
Hi,
This is the first Python code i have written without the aid of a tutorial, i was wondering if you could look over it and provide me with your feed back on any bad habits i may have and if there was an easier way to write this, Your feedback would be greatly appreciated.

Thanks

import time
print "Welcome to my measurement converter"
print "This converter will convert meters into yards"

Meters = int(raw_input("Enter the number of meters"))
Yards = Meters * 1.094
print Meters, "Meters is equal to", Yards, "yards"

time.sleep(5)

Why don't you post it in a new thread so that we don't muddy up the tutorial thread with random comments.

Editor: Thanks, this post has been moved to its own thread.

Re: Projects for the Beginner

Python is very well suited for text modifications. Write a small Python program that modifes this typical raw email text:

Re: Projects for the Beginner

You pay 2 Dollars and you are allowed to throw 4 dice. If the sum of the dice is less than 9, you win 12 Dollars, otherwise you lose your investment. Should you play this game?

Let a small Python program help you.

Re: Projects for the Beginner

How about making a program that will get your weather forecast for tomorrow?

You can use modules such as urllib2 and things like that to get the source code of your favourite web weather forecaster and then scrape off all of the html tags to leave you with your forecast for the next few days.

Re: Projects for the Beginner

Let's have some fun with mathematics, write a Python program for each question:

1) What do you get when you add up the numbers 1-100 consecutively?

2) What number multiplied by itself gives the number 12345678987654321?

3) What five digit number, when multiplied by the number 4, gives a number with the digits in reverse order?

Re: Projects for the Beginner

Write a simple calendar program. One that will remember dates that you have set. For this you would have to save it in some place.
Perhaps take a look at Pickle modules. This can be used to save instances and the like.

This program could be used very well in a GUI in fact wxPython has a specific built in object for making a calendar...

Python30 has been released, install it and go through much of the existing sample Python code and rewrite it so it will work on Python30.

Re: Projects for the Beginner

Write a programmer's calculator that shows a numeric integer entry in denary (base10), binary(base2), octal(base8) and hexadecimal (base16). Allow entry in any of these bases.

Also does some simple binary stuff like shift-left and shift-right, binary or, binary and and binary xor.

If the integer falls into the ASCII range, display its character or meaning.

Re: Projects for the Beginner

Write a program that gets that latest comic from your favourite webcomic.
For this you could use urllib to download the images.
