String question

[Andreu]

I want to split a sentence and assign each word to a variable.
In Ruby I can do it as:

v1,v2,v3,v4,v5 = str1.split

Which will be the Python equivalent ? Thanks.

Andrew.

That would be:

str1 = "The quick brown fox jumps"
v1, v2, v3, v4, v5 = str1.split ()

Well a straight copy would be...

>>example = "Hello, how are you"
>>v1, v2, v3, v4 = example.split()
>>print v1, v2, v3, v4

Hello, how are you

>>print v1

Hello,

However I would make a list of it.

>>v_list = example.split()
>>print v_list

['Hello,', 'how', 'are', 'you']

>>for word in v_list:

print word
Hello,
how
are
you

That seems to me to be the more pythonic way to do it, since it is
dynamic.

Re: String question

Yes, ... don't ask me why, but in fact v1,v2,v3 = str1.split()
does not seem to work. My original problem was I forgot about
the parenthesis as Tim point out. So I ended up converting to a
list as in: v = str1.split() and accessing the elements using
v[0] v[1] ect...it is working now. Thanks.

v1,v2,v3 = str1.split() will only work if there are exactly three things in
str1.

>>s = 'this is a test'
>>v1,v2,v3 = s.split()

Traceback (most recent call last):
File "<interacti ve input>", line 1, in <module>
ValueError: too many values to unpack

>>v1,v2,v3 = s.split(' ',2) # limit to two splits maximum
>>v1

'this'

>>v2

'is'

>>v3

'a test'

In Python 3k I believe you can put a * next to one of the variables to
hold multiple arguments. That'll be aidful!

IDLE 3.0b1

>>a,b,*c=[1,2,3,4,5]
>>c

[3, 4, 5]

>>a,*b,c = [1,2,3,4,5]
>>b

[2, 3, 4]

>>a,b,*c=[1,2]
>>c

[]

Augmented assignment is quite similar to argument passing:
at most one starred target;
at least as many items as un-starred targets (as now).
