You can go into creative by opening the command bar (key /, I use G) or chat bar (key T, I use J) and type:
Either /gamemode c (slash already there if in command bar)
or /gamemode 1 (same)
Note that you cannot get certain items usually, you must craft and/or give yourself them, such as fireworks and command blocks.
Hope this helped and happy building!

If you are playing on a PC single player mode, type /gamemode s This will toggle the gamemode back to survival mode.
No, multiplayer has no effect on your already existing single player worlds.
single player mode on minecraft
I believe that creative mode is the online version of minecraft that can be found on the website that does not require an account. Improved answer: Actually, that's not entirely true. The version that you can find online for free is Minecraft classic - which IS a form of creative mode (as you can't die, and you have unlimited amounts of all blocks available), but it's very outdated and people don't refer to it as "creative mode". Minecraft Creative is available in and part of 1.8 Beta with all regular blocks that you know from the current Minecraft version. I don't play online, so i don't know how to switch to creative there, but when you're in single player this is how you get creative mode: 1) In single player, click on "create new world" 2) Choose mode "creative mode" instead of "survival mode" And that's it. Very easy. :D Improved answer yet again: Yes all of those answers are correct, but they don't entirely answer the question. In single player you do select survival, hardcore, or creative mode, but in multiplier you must be and operator to be creative or an operator must set you to creative. The command for that is you type /gamemode (username) 0 for survival and 1 for creative. :D And there you have it!
You need the single player commands mod. Then you type /gamemode 1. This will change your survival world to creative. To put it back use /gamemode 0.
