I need to split a text like:
//string
s = CS -135IntrotoComputingCS -154IntroToWonderLand...
in array like
inputarray[0]= CS -135 Intro to computing
inputarray[1]= CS -154 Intro to WonderLand
.
.
. and so on; I am trying something like this:
re.compile("[CS]+\s").split(s)
But it's just not ready to even break, even if I try something like
re.compile("[CS]").split(s)
If anyone can throw some light on this?
You may use findall with a lookahead regex as this:
>>> s = 'CS -135IntrotoComputingCS -154IntroToWonderLand'
>>> print re.findall(r'.+?(?=CS|$)', s)
['CS -135IntrotoComputing', 'CS -154IntroToWonderLand']
Regex: .+?(?=CS|$) matches 1+ any characters that has CS at next position or end of line.
re.findall(r'.+?(?=CS -|$)', s)Although findall is more straightforward but finditer can also be used here
s = 'CS -135IntrotoComputingCS -154IntroToWonderLand'
x=[i.start() for i in re.finditer('CS ',s)] # to get the starting positions of 'CS'
count=0
l=[]
while count+1<len(x):
l.append(s[x[count]:x[count+1]])
count+=1
l.append(s[x[count]:])
print(l) # ['CS -135IntrotoComputing', 'CS -154IntroToWonderLand']
135IntrotoComputingCSto-135 Intro to computing? (Unless they are all in "intro to x" format which I don't think it is) Where are you getting this data? Maybe you can get it in a better format.
