#93975 — Need assistance

I need help writing a homework program. 

I'll write it, but I can't figure out how to incorporate what I have read in the book to work in code.

The assignment wants us to take a users first, middle and last name in a single input ( name=('enter your full name: )).

Then we must display the full name rearranged in Last, First Middle order. 

I tried to use the search function in Python to locate any spaces in the input. It spot back the index 5 (I used Craig Daniel Sirna)

That is correct for the first space, but I can't figure out how to get it to continue to the next space. 

The indexing process is also a bit confusingto me. 

I get that I can use len(fullName) to set the length of the index, and how the index is counted, but after that I'm lost. 

I have emailed my professor a few times, but haven't gotten a response.(online course)

Any help would be greatly appreciated.

Which search function are you talking about?  Is it a string method or
something else?

One of the first string methods I learned about when I first started
with Python was the .split() method. For example, in the interactive
shell try this:

>>> a="one,two,three"
>>> a.split(',')

Does this help at all?

Which part of indexing is confusing?  The syntax for slicing? I admit I
sometimes find it a bit complicated to know when and where to use -1 as
the index.

#93980

I am in bed, on my phone,  gotta be up in 4 hours for work. I will get back with you guys tomorrow after I take care of my Math class stuff. I need to step away from this for a day lol. 

Worst part...this is the C assignment and it's driving me crazy. 

I do recall the list fuction. But isn't it imperative that I have the index of the spaces in the string name?

I use the Fullname.isspace function.

Sounds good. I had hoped to merely point him in the right way, and that
he would put things together.  I hope this is indeed the case.

1) Use the interactive console.  Set x = 'Craig Daniel Sirna' and play 
with indexing and slicing it until you really internalize what they 
mean.  x[3], x[-3], x[0:10], x[0:-1].  It's not actually relevant to the 
problem at hand, but right now is the time in your education to get 
indexing down cold; skimp on it now and you'll pay for it forever.  
Should take you about 5 minutes.

2) https://docs.python.org/3/library/stdtypes.html#string-methods
You can do what you're trying to do, but you're swinging a hammer with a 
powered nailgun at your feet.  Search is an inefficient way to try to 
split a string into parts based on a delimiter.

Most likely it's not him. They will learn it later during the course. ;-)

I'll throw in something to emphasize a major difference between indexing 
and slicing.

 >>> x = 'Craig Daniel Sirna'
 >>> x[100]
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
IndexError: string index out of range
 >>> x[100:]
''

Inefficient I don't know about, and mostly don't care about either, but 
certainly not the cleanest way to code, at least IMHO.

To generate a list of words from a string, split the string up on the 
spaces between words. See the split method of strings.

Having a list of words, get a copy of the list in reverse order. See the 
reversed function (and maybe the list function).

Note - reversed returns an iterable, list will convert the iterable to a 
list.

To join the elements of a list into a string, see the join method of 
strings.

That won't really help, because the desired order is, with the example 
the OP used: Sirna Daniel Craig. So here indexing is necessary, but 
indexing of the list elements, not of the characters in the string.

(Necessary is too strong, because this could be done with rpartition. 
But I doubt that's the right answer for a beginner course.)

Oh, then it's even easier, yes, it's mainly a case of list indexing.

1) Split the original string into a list of words (string.split() method)
2) create a sublist (s1) of the last element
3) create another sublist (s2) of the first to penultimate elements
4) combine the two sublists
5) use the string.join() method to combine the sublist elements into a 
single string

I think most pythonistas would probably combine steps 2 through 4 in a 
single line of code, possibly even steps 2 through 5.

If you use rsplit, you can do it in one line.

You don't have to index them.  You can unpack them into a tuple

	That only works if the input IS three names (My Birth Certificate reads
"Dennis Lee James Bieber"; and I often used to include my confirmation name
into the thing; I've grown out of that phase but do still sometimes use
dljjb as initials).

	Simple .split() and a {HP calculator} roll operation should get the
desired order.

HP calculators were proper in that they used RPN entry.

i.e. 2 enter 2 + would show 4 instead of 2 + 2 =

Gawd it's so long but ISTR there were 3 stack registers and the display. 
So you could press

1 enter
2 enter
3 enter
4

and Z = 1, Y = 2, X = 3 and display = 4. Roll would rotate the entries 
through the display register.

ROLL and Z = 2, Y = 3, X = 4 and display = 1

and so on. There was an INV ROLL to go the other way.

The 3 level stack was equivalent to nesting parentheses three times. I 
only had a TI-59 as it was half the price of an HP67. The TI had more 
memories and program steps and was faster. But it didn't say HP on the 
front!

I have an hp35.  But to be 'really' cool you have to have an hp35 that
just says hp.  Those were the very first ones
