to open a file in python and print the first word and the last word of the first line, and so on with all the lines of the file.

Question

Hello everyone !! I have a problem: I want to open a file in python and print the first word and the last word of the first line, and so on with all the lines of the file. Can anybody help me ?

Answer 1

f = open("filename.ext", "r") # open the file in readonly mode
lines = [] # create an empty list to store the lines in the file

for line in f:
lines.append(line) # loop over the lines in the file and store them in the lines list

for line in lines:
words_in_line = line.split() # create a list of the words in each line
print(word_in_line[0], words_in_line[-1]) # print out the 1st and last word of each line

OR do it all in 1 loop

f = open("filename.ext", "r")

for line in f:
words = line.split()
print(words[0], words[-1])

Answer 2

if I wanted to do that, I would use the shutil module for the file handling

https://docs.python.org/3.0/library/shutil.html

after using that to open the file I would write a for loop to iterate over each line and print the first and last word
