Welcome to another issue of Full Circle magazine. nd welcome to another new series! I promised you LAMP, and here it is: creating your own LAMP server. LAMP stands for Linux, Apache, MySQL and PHP (sometimes Python) and is the foundation upon which many an Internet server sits, so it is very widely used. In part one (this month) ARichard Bosomworth discusses the installation and administration of a LAMP server and, next month, will touch on FTP and Firewalls, so stay tuned!
Also this month, Greg has a small correction to his Python Part 1 series, so make sure you check that out, and he goes on to talk more about variables. Ubuntu is a complete operating system that is perfect for In other news, just last week Karmic Koala (Ubuntu 9.10) reached Alpha 4, and laptops, desktops and servers.

For example if we I will introduce before we get to Mar has 31 days. assign the string 'The time has word 'time' is, we could use our next programming Apr has 30 days. come' to a variable named example. When we want to May has 31 days. pos = strng.find('time') print something that includes Jun has 30 days. strng, and then wanted to Jul has 31 days. know what the second literal text as well as variable Now, the variable pos (short Aug has 31 days. character would be, we could text, we can use what's called Sep has 30 days. for position) contains 4, saying type: Variable Substitution. To do this Oct has 31 days. that 'time' starts at position 4 is rather simple. If we want to Nov has 30 days. in our string. If we asked the Dec has 31 days. strng = 'The time has come' substitute a string, we use '%s' print strng[1] find function to find a word or and then tell Python what to Something important to sequence that doesn't exist in substitute. For example, to understand here is the use of The result would be 'h'. the string like this: print a month from our list single quotes and double Remember we always count above, we can use: from 0, so the first character pos = strng.find('apples') quotes. If you assign a variable would be [0], the second would print 'Month = %s' % to a string like this: be [1], the third would be [2], the returned value in pos would month[0] st = 'The time has come' and so on. If we want to find be -1. the characters starting at This would print 'Month = or like this: position 4 and going through We can also get each Jan'. If we want to substitute an position 8, we could say: separate word in the string by integer, we use '%d'. Look at using the split command. We the example below: st = “The time has come” print strng[4:8] will split (or break) the string at each space character by using: Months = the result is the same. ['Jan','Feb','Mar','Apr','May However, if you need to include which returns 'time'.
