Charles Sharon, and other listeners,
No, the indentations are necessary for the program to run
correctly.
The indentation is instead of braces.
If you check out Edsharp’s documentation and look for the word
“brace” or “{“ you will (eventually) get to a section which allows programmers
to use braces the way they are used in most other languages.
As I recall, there is a utility to convert from braces to indented lines.
I have not tried it.
What you have to realize is that to either run your code you have to use the
utility to make indents for the Python interpreter.
And if you are working collabrativly, where different programmers are not using
braces as other languages do,
then you will be obliged to run the utility on whatever piece of code you have
written or modified.
The same goes for every piece of code that you input from the shared folders.
I started to run into this problem when I was doing code development in Python
where
I was using Tabs for indenting and everyone else was using spaces (which
conforms to Python coding style standards).
everybody using spaces to indent (3-4 spaces for each level).
My boss was "scared silly" with this solution to the conversion problem,
because I was transforming code,
and if it didn't work it could really mess things up for whatever code was
being transformed.
What you might do instead is to use "# {" instead of "{".
You cannot do it at the beginning of a line, or the line is commented out.
But could do it on a separate line or at the end of a line.Even so, you would
probably have the single line comment-brace indented to the same level as the
previous line
and the correxponding right brace would have to be outdented once
from the previous line.
Edsharp has the ability to match corresponding braces may discover that it's a
problem in Python.
I'm not sure it's smart enough to skip any braces in quotes or comments.So it
might not work too well for what I have suggested above.
Look, I hear ya, and I've been there.
I've wasted a good chunk of time when I rarely get the indents wrong and have
to figure out where the problem is.
So lack of braces may seem to create problems.
But after awhile you get used to it.
and stop making as many mistakesI'd say this problem became rare after about 4
weeks of python usage.
One additional problem is that braces and brackets are both used in real code,
just not to define a block of code.
One trick that could save you a lot of time:
After you select a block of text,
if you press "tab" or "shift-tabb" you will put or remove a tab at the
beginning of each line in the block of text.
This is not so useful when writing code,
but it can be of great value in importing a section of code from another
program where the indentation may be different from what you need.
and after testing, run a utility to change the leading tabs to the appropriate
number of spaces that your group is using to do an indent.
You will find more detail in Edsharp documentation.

Are there different levels on indentation? If so, wouldn't the program run
differently when different lengths of indentation is used? Or are you speaking
only of representation for reading purposes rather than for actual code
writing? Thanks.

A close relative to Sharon’s code format issue is how many spaces to use in
code examples. This may be controversial.
Although four spaces is the most common indentation, I suggest two spaces per
indentation level will work better especially for email. Two and four spaces
are both common standards, but four spaces eats too much page territory.

Maybe you could type, indent 2, indent 4, ectcetera, then type the colon before
skipping the line?
