However, I will say one thing: you seem to have made a really complicated job out of something as simple as be able to run Python programs from the shell. For starters, I'm pretty sure Mac OS X comes with Python automatically. Perhaps not the most recent version, but I'm sure it will be there. Just try running python from the shell, and it should Just Work. If you want to install the most recent version, you shouldn't need to install pygame, then uninstall pygame. It shouldn't take eight steps to install the latest version of Python! (Even installing from source code under Linux, it only takes five: download, extract, configure, make, install.) My suggestion is you try something like the Mac installer for ActivePython: http://www.activestate.com/activepython/downloads The instructions here are pretty old, but they should give you some hints: http://diveintopython.org/installing_python/macosx.html Or just use the Mac installer from here: http://www.python.org/download/ -- Steven ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Well everybody, sorry for the incomplete sentences and overall poor English but I wanted to make this simple to read and understand for someone who is completely inexperienced in any sort of programming, as I am (very first day messing with this stuff, e.g., terminal). This is the result of hours of Googling that was all done in one day. Perhaps someone who is familiar with the commands below (in bold) wouldn’t mind explaining what exactly is taking place. Additionally, this was all done in terminal on a MacBook Pro running Mac OS Lion. 1. Install macport binary (comes with installer; easy) 2. sudo port install py-game a. not sure if this is necessary, as it doesn’t appear to cause pygame to be functional for python version 2.7.1 (stock python on lion) 3. sudo port select --set python python 2.7 a. I believe this set the default python version to 2.7.2 which I also believe was downloaded during step 2 (therefore why I think this ends up being a necessary step) 4. Download setuptools-0.6c11-py2.7.tar 5. In folder gasp-0.3.4, which appears after clicking on the .tar, place setup.py in the gasp folder 6. sudo python gasp/setup.py install a. make sure your directory is the folder gasp-0.3.4 7. sudo port –v install py27-gtk a. takes about an hour for this step to complete 8. sudo port uninstall py-game a. this step is not necessary for gasp to work; I simply didn’t want any unnecessary stuff on my computer that was downloaded during the second step; however, this step put python 2.7.2 on my computer; could install 2.7.2 separately I guess but this way worked for me; a lot of other unnecessary stuff is installed during this step too but I think it’ll remain even after this command, oh well ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

A dollar sign is the generic way of indicating a Unix shell prompt. cat is a Unix command which catenates the output to a file, again using cat like this is a generic way of sayong create a file containing whatever follows cat. In practice you would use a text editor like vim or pico etc. means the python prompt. You are typing a Unix command into Python which doesn't reciognise it, hence the error. My apologies for not being explicit. I assumed since you were using the shell to run sudo port install that you were an experienced Unix shell user and would understand the significance of $. (Incidentally % is the generic way of indicating a rioot user command, so % cat mydfile implies login as root (or use sudo) to type the command) Then use chmod +x to make it executable $ chmod +x myscript.py When I try to run this with one of my files I get the following error: chmod +x tryme1.py Same problem. chmod is the unix command to Change Mode of a file. $ myscript.py Alternatively you can just call python explicitly: $ python myscript.py I get a syntax error doing this too: python tryme1.py And again, you type python on its own to start a Python interpreter session.
