going form a list to a bunch of strings

[Patrick C]

lets say i have a list called

thelist = ['student A got a 78 on their exam;\n student B got a 68 on their exam;\n student C got a 58 on their exam;\n']

Now if I wanted to make each word its own string I could do .split(), but lets say I wanted to break it up per sentence (ie:'student A got a 78 on their exam' is one string)

What if I wanted to do it simply by the # of items in the string...that is, which might work in this situation....go ever 8 items (that is, words) then make a new sentence. Of if I wanted to be weird i could go ever 2 words o i'd get...
'student A', 'got a', ' 78 on', 'their exam'

lastly, if i wanted to break up upon a character, such as the semicolon at the end of each sentence.

Thanks

For the first part, use the optional argument to str.split():

>>> s = 'student A got a 78 on their exam;\n student B got a 68 on their exam;\n student C got a 58 on their exam;\n'
>>> s
'student A got a 78 on their exam;\n student B got a 68 on their exam;\n student C got a 58 on their exam;\n'
>>> sentences = s.split('\n')
>>> sentences
['student A got a 78 on their exam;', ' student B got a 68 on their exam;', ' student C got a 58 on their exam;', '']

Try this for splitting on words:

def splitwords(words, n): # number of words
    return [' '.join(words[i:i+n]) for i in range(0, len(words) - n, n)]
 
thelist = ['student A got a 78 on their exam;\n student B got a 68 on their exam;\n student C got a 58 on their exam;\n']
words = thelist[0].split()
new = splitwords(words, 2)

>>> s
'student A got a 78 on their exam;\n student B got a 68 on their exam;\n student C got a 58 on their exam;\n'

Don't know why you'd want to do this, but:

>>> for sentence in sentences:
...     print [" ".join(tup) for tup in zip(sentence.split()[::2], sentence.split()[1::2])]
...     
['student A', 'got a', '78 on', 'their exam;']
['student B', 'got a', '68 on', 'their exam;']
['student C', 'got a', '58 on', 'their exam;']
[]
>>>

I'd like you to notice the "new" in red. "new" is a python reserved word and should not be used as a variable name (just like "list", "dict", etc).

Are you sure though?:

>>> new
 
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    new
NameError: name 'new' is not defined
>>> 
 

That's wierd. Maybe it's in older versions?

Oh Opps. It's a module. Not as bad as a reserved word though. Plus, I've never heard of the new module. And just checked, the module is deprecated.
