goto, cls, wait commands

[BOOGIEMAN]

I've just finished reading Python turtorial for non-programmers
and I haven't found there anything about some usefull commands I used in
QBasic. First of all, what's Python command equivalent to QBasic's "goto" ?
Secondly, how do I clear screen (cls) from text and other content ?
And last, how do I put program to wait certain amount of seconds ?
If I remeber correctly I used to type "Wait 10" and QBasic waits 
10 seconds before proceeding to next command.
