Dear Group,
I am trying to search the following pattern in Python.
I have following strings:
(i)"In the ocean" (ii)"On the ocean" (iii) "By the ocean" (iv) "In
this group" (v) "In this group" (vi) "By the new group"
.....
I want to extract from the first word to the last word, where first
word and last word are varying.
I am looking to extract out:
(i) the (ii) the (iii) the (iv) this (v) this (vi) the new
.....
The problem may be handled by converting the string to list and then
index of list.
No need for a regular expression.
py> sentence = "By the new group"
py> words = sentence.split()
py> words[1:-1]
['the', 'new']
Does that help?
I thought OP wanted:
words[words[0],words[-1]]
But that might be just my caffeine deprived misinterpretation of his
terminology.
>>> sentence = "By the new group"
>>> words = sentence.split()
>>> words[words[0],words[-1]]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: list indices must be integers, not tuple
So why would the OP want a TypeError? Or has caffeine deprivation
affected your typing skills? :)
