Re: [Tutor] Adding numbers within a string

2016-10-13 Thread D . V . N . Sarma డి . వి . ఎన్ . శర్మ 
Then Isaac's function does that(but you have to leave a space after
last number in the string).

def foo(x):
a, b = 0, ""
for i in x:
if i != " ":
b += i
else:
print ("this is b", b)
a  += int(b)
print ("this is a",a)
b = ""
print ("final a ",a)

foo("10 5 8 ")

Sarma.

   You can write your own str.split or just use while loop.

 To whom it may concern,
 Can someone enlighten me as to how you can create a function such
 that sum_numbers('10 5 8'), when run, will give an answer of 23, without
 using str.split() and using a for loop

It is even more confusing - split() may NOT be used
but 'for' MUST be used...

def string_sum(s):

  for item in items:
   total += int(item)

You can call the function as

string_sum("10 4 5 ")

Output will be 19.

this should help you solve it. figure a way to add the last number. if any 
troubles ask again.

def sum_numbers(x):
for x in [1]:
print(23)

Your instructor will probably be displeased with that answer, but it meets
the requirements.

It would be nice if our teachers could models writing good requirements.

What do you think a good requirement statement would be?

I'm assuming this is some kind of classroom exercise?
Otherwise the advice is just use string split()!

If it is a class  exercise then the easiest option
is to write your own string split(). That is a
function that takes in a string and spits out
substrings. To do that you need to traverse the
string and look for separators. Store the characters
between separators in a list. return the list.

Another way to do it is to use a regular expression
to detect the groups of characters - do you know
about regex?

Once you have done the splitting you need to
convert the substrings into numbers and add
them.
