如何从python中的最后一个单词到第一个单词读取txt文件上的单词（或字符）？

Question

Example: I have a file as :
filename1 = "I am a student" (inside filename1 have I am a student )

f = open(filename1)
string = f.read()
spl = re.split('\s|(?<!\d)[,.](?!\d)',string)
f.close

print spl will show: I am a student , but I need the result as [student a am I] could you answer me please... Thanks in advance.

Answer 1

You can reverse the list with a martian smiley :

spl = spl[::-1]

Or, if you just need an iterator:

spl = reversed(spl)

Answer 2

str=['im a student','im a teacher']
list=[]
for x in str:
   new=""
   for y in [x for x in reversed(x.split())]:
       new+=y
       new+=' '
   list.append(new)

print list // ['student a im ', 'teacher a im ']
