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 "<interactive 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'
