Subject: [Idle-dev] Problem with the latest version of Python on macOS

Hello,
I downloaded Python recently on my computer and I have some troubles making it work. It doesn?t allow me to make and if function and elif without the good indentation. I have the latest version of Python (3.7.4) and my mac is updated (macOS Mojave 10.14.5).
As you can see in the picture, the ?if? doesn?t align properly. I tried with else, elif, if, and every time I hit ?send? it sends me to the wrong indentation.
My dad needs this for his work and he?s trying to learn Python but sadly he is stuck.
Thank you for your help.
Best wishes,
Sara

It is in 3.8.0b3, released two days ago, and is working nicely for me on 
Windows.  Thank you Tal.

Most python mail lists do not allow binary attachments.  idledev 
currently does, but attachments do not follow responses.  It is also 
impossible to copy from images to determine what you entered.  Please 
copy and paste instead of attaching screenshots.

 >>> if a > 0:
	print('positive')
if a < 0:
	
SyntaxError: invalid syntax

With 3.7.3 on my Mac and 3.7.4 on my Windows machine, the second 'if' is 
highlighted as an error with black type on brownish red  background. 
But I don't see this on your screenshot.

Did you create a custom theme with this disabled?  If you go to Options 
=> Configure IDLE => Hightlight tab and select Builtin theme IDLE 
classic, is the word 'error' not so highlighted?

> the ?if? doesn?t align properly.

You have mixed together two issues.  First the syntax: '>>> ' in IDLE's 
Shell means 'Enter *one* python statement. An 'if' statement can be 
followed by multiple 'elif' line and one 'else' line.  The second 'if' 
starts a second statement, which is an error when your entry is 
interpreted as one statement.  The following single statement works.

 >>> if a > 0:
	print('positive')
elif a < 0:
	print('negative')
else:
	print('zero')

	
positive

> I tried with else, elif, if, and every time I hit ?send? it sends me to the wrong indentation.

Second, the indentation.  The 'if', 'elif', and 'else' lines have the 
same indentation: none.  You have to ignore the prompt.  It is not 
counted as indentation.  This awkward convention, and the use of tabs, 
is a side-effect of Shell's feature of working with statements instead 
of physical lines.  I am preparing a new tracker issue to do away with 
prompts interfering with code and tab indents.  It will make code entry 
in Shell the same as in IDLE's editor, so one could enter

if a > 0:
	print('positive')
elif a < 0:
	print('negative')
else:
	print('zero')

	
positive

the same in both places.

Not really.  Believe SyntaxError and try to get the error highlighting 
working.

This is in 3.7.4 and 3.8.0b3.  Run => Run Customized, enter in box. 
Entry will be put in box (editable) on next invocation.

It's not bad indentation.  If that were the problem, you'd get
`IndentationErrror`.
(The indention is good despite looking weird because the `>>> ` is not part
of the code - imagine your first `if` starting at colunn 0.)

The problem is that IDLE Shell window expects a single expression/statement
per prompt, and you gave it 2 separate `if` statements.
In many such cases python 3 will give clear "multiple statements" error,
but not here.
You can confirm this by changing second `if` to e.g. `elif` (which makes
them one statement) - that works for me.

Same syntax would be fine in a .py file editor window - most python scripts
contain many statements
It's just limitation of the Shell window - you should execute each
statement separately by pressing Enter (possibly twice).

Tip: if you do want to paste many statements together, put them all inside
an `if True:` block to turn them into 1 statement.
If the copied code was not indented, select all pasted code, press Ctrl+]
(aka Format -> Indent region - this menu is only visible in editor window
but the shortcut works in Shell window too).
