hi i have a list (after reading from a file), say data = [ 'a','b','c','d','a','b','e','d']
I wanted to insert a word after every 'a', and before every 'd'. so i
use enumerate this list:
for num,item in enumerate(data):
if "a" in item:
data.insert(num+1,"aword")
if "d" in item:
data.insert(num-1,"dword") #this fails
but the above only inserts after 'a' but not before 'd'. What am i
doing wrong? is there better way?thanks
