Answer:

See explaination

Explanation:

import os

import time

from stat import *

file = input("Enter file name: ")

details = os.stat(file)#stores statistics about a file in a directory

print("File size: ", details[ST_SIZE])#retreiving size

print("File last accessed time: ", time.asctime(time.localtime(details[ST_ATIME])))#access time

print("File last modified time: ", time.asctime(time.localtime(details[ST_MTIME])))#modified time

print("File creation time: ", time.asctime(time.localtime(details[ST_CTIME])))#creation time

print("First character: ", file[0])

print("Middle character: ", file[len(file) // 2])

print("Last character: ", file[len(file) - 1])

num_words = 0

num_lines = 0

f=open(file, "r")

lines = f.readlines()

for line in lines:

num_lines = num_lines + 1

num_words = num_words + len(line.split())#add no. of words in that line

print("Number of lines: ", num_lines)

print("Number of words: ", num_words)

Write a shell (text-based) program, called first_word.py, that opens the file stuff.txt and prints out the first word of every l
postnew [5]

Answer:

See explaination

Explanation:

Please check below for the code for first_word.py file which will print first word of an input file stuff.txt. So the open function will open file in read mode. We had maintained a count variable so that we can skip printing first word of first line. Also the command line.strip() checks whether string is empty or not so that we will not get index error while calling split function over line to get first word.

#!/usr/local/bin/python

stuff = open("stuff.txt", "r");

count = 0;

for line in stuff:

count+=1;

if (count>1 and line.strip()):

print(line.split(maxsplit=1)[0])
