Hello
Suppose I have a textfile (text1.txt) with following four words:
Apple
balcony
cartridge
damned
paper
bold
typewriter
and I want to have a python script that prints the words following the
word starting with the letter b (which would be cartridge) or
differently put, a script that prints the element following a
specified element:
I am more experienced in Perl, and a beginner in python
I wrote a script that - of course - does not work, that should print
the element in a list following the element that starts with a b
import re
f = open('text1.txt', 'r')
list1 = []
list2 = []
for line in f:
list1.append(line)
a = re.compile("^b")
int = 0
while(int <= list1[-1]):
int = int + 1
a_match = a.search(list1[int])
if(a_match):
list2.append(list1[int + 1])
print list2
I did not find information about addressing previous or following list
elements. So some help would be magnificent
Thanks a lot
