I keep pressing enter out of habit. How do I start a new line?

print "Halt!"
user_reply = raw_input("Who goes there? ")
print "You may pass,", user_reply

[Melchoire]

try "Who goes there? \n"

[iargue]

You start a new line by pressing enter...

[Ozonewolf]

Nawwwwww like I didn't try the enter button....

And the /n didn't work either. I'm using Python 2.6 if that helps

[Melchoire]

ur just trying to add a newline after "who goes there?" right?

[Ozonewolf]

Yeah. I'm literally just trying to add a new line.

print "Boo"
print "I see you"

Posts as

Boo
I see you

[iargue]

I really dont see what problem your having...

[Ozonewolf]

print "Boo"
print "I see you"

DOESN'T come out as

Boo
I see you

I can't get the next print on the line underneath. The best I can do is one string.

Are you using IDLE?

[Ozonewolf]

Yes

[iargue]

Idle uses line by line processing, so you cannot execute two things at once, unless they are part of a function.

To do this in python, type

def printit():
	print "Boo"
	print "I see you"

Then press enter twice.

Then type

printit()

Idle is good for testing out an idea, but for real programming, get an editor such as, Gvim, and then execute it using Python.

I'm just starting out for now, thanks i'll try that.

Can you tell me what the 'def' means?

[iargue]

Essentially "define"

It basically creates a function.

When you type Def printit():

You are defining the function printit. Then everything past that point that is indented, is part of that function.

After you decrease the indent, then you leave the function.

Nawwww F*CKING H*LL this is soooo f*cking simple and I'm screwing it up (wait can you swear uncensored here??)

I seriously can't get a simple line underneath a line. What do I press? Enter doesn't work, neither does /n or :

It goes

>>> print "blah"
>>> print "blah

and then I can't edit the first print so its a seperate command alltogether. *turns to google*

[iargue]

Press enter twice and it will unindent and end the function.

[Ozonewolf]

Nope...ugh im gonna browse google for answers, i sound like a idiot on here. Thanks for trying though, its 99% likely its my fault

[Dan]

def hello_world:

	print "hello\r\n"

	print "world"



hello_world()

Hmm, I believe someone earlier said to use \n not /n for a newline character in most languages.

tried that too it says 'unexpected characters after liine continuation character'

[SmokingKush]

Strings automatically end with a new line character ( \n ), other than that you can edit the ending character with the (, end = ' ' ) argument. If I understand correctly, your problem is you're entering the code on idle python shell command prompt and not in the editor. Just press Ctrl + N (or file --- new window) and there you'll be able to enter print statements on multiple lines.

I read most of the posts and kinda got the jist of the problem...

print "Halt!"
user_reply = raw_input("Who goes there?\n")
print "You may pass, ", user_reply 

is what your going to want.

Here is the following "line breaks" for the different platforms:
Unix (linux, etc)... \n
Windows \r\n
Mac \r

to use "print" and not have it put a new line out you type:

print "my text without a new line", #note the trailing comma
print "my text with a new line"

import sys
sys.stdout.write("a much faster way to write without a new line")
sys.stdout.write("lets add a new line\n")

Let me know if that clears things up
