如何在每行中拆分单词？

Question

I wrote a code to get each word in a line of a text file. Please see below.

fname = input('Enter your file name:')
try:
    fhand = open(fname)
except:
    print('File cannot be opened:', fname)
word=[]
for word in fhand:
    word = word.split()
    print(word)

I run this code and I got what I want it. But, when I just run print(word) , it only shows words of the last line. I think I didn't define word in the beginning. Then I added word = [] but the results are the same.

Answer 1

in your loop -

for word in fhand:

you reassign the variable 'word' everytime it loops. Since you made 'word' a list, you would need to append to it the new lines instead of reassigning it. Also, there is probably some issue with using 'word' twice, once as a list and once in your for loop counter. Try something like-

word = []
fname = input('Enter your file name:')
with open(fname, 'r') as file:
   for line in file:
       word.append(line.split())
