Hi,
I'm having a go at using ipython as a command prompt for data
analysis. Coming from Matlab, I'm used to typing multiple commands on
the same line then using the up arrow to go through my history.
How can I write multiple python commands on the same line?
You can write multiple *simple* statements using ';'.
E.g. "x = 0; while x< 10: x = x + 1;" returns an "invalid syntax"
error on the 'e' in while.
All compound statements, like while, must start on own line.
Also, how can I produce a new line, without it running the command?
Use an editor, as with IDLE, rather than a shell. Interactive mode runs
*1* statement (including simple;simple) at a time.
would have expected a ctrl-enter or shift-enter to produce the
expected results.
E.g. I want:
"x = 0;<ctrl-enter>
This is one statement
while x< 10:<ctrl-enter>
x = x + 1;<ctrl-enter>
This is another.
I can understanding wanting to rerun initialized loops with one enter,
but you cannot. Sorry.
