=>
f = open("a.txt","r")
l = f.readlines()
f.close()
print(l) 




2. WAP to read a file line by line and store it in a array.
=>
import random
from array import array
f = open("a.txt","r")
l = f.read().splitlines()
a = array('i',[])
for i in l:
    a.append(int(i))    
print(a)




3. WAP to read a random line from a file.
=> 
import random
f = open("a.txt","r")
l = f.read().splitlines()
print(random.choice(l))
f.close()




4. WAP to combine content of 2 files line by line.
=>
f1 = open("a.txt","r")
f2 = open("B.txt","r")
l1 = f1.read().splitlines()
l2 = f2.read().splitlines()
n = min(len(l1),len(l2))
for i in range(n):
    print(l1[i],l2[i])
if len(l1) > len(l2):
    print(*l1[i+1:])
else:
    print(*l2[i+1:])




5. Write a Python Program to generate 26 files named A.txt to Z.txt.
=>
name = ord("A")
extension = ".txt"
for i in range(26):
    filename = chr(name)+extension 
    x = open(filename,"w")
    x.close()
    name += 1




6. Write a program to create a file where all letters of english alphabet are listed by specified no. of letters in each new line.
=>
import string
letters = string.ascii_uppercase
print(letters)
n = int(input("Enter a no. to print no. of char. in each line "))
i=0
f = open("a.txt","a")
while(i<26):
    f.write(letters[i:i+n]+"\n")
    i += n   
f.close()





7. Show data of coronavirus for india and all over the world.
=>
import requests
import time
from bs4 import BeautifulSoup
url = "https://www.worldometers.info/coronavirus/country/india/"
page = requests.get(url)
soup = BeautifulSoup(page.content,'html.parser')
b = soup.findAll("h1")
c = soup.findAll("div",{"class":"maincounter-number"})
b = b[1:]
t = time.ctime().split(" ")[3].split(":")[0] # for updating each hour
while(True):    
    if int(time.ctime().split(" ")[3].split(":")[0]) > int(t) : # for eg. t=2 then as 3 o'clock will be the time we will update the data
        t += 1                                         # here now current time is 3 then data will be update at 4
        print("CoronaVirus cases in India =>")
        for i in range(len(b)):
            print(b[i].text,c[i].text)
        url = "https://www.worldometers.info/coronavirus/"
        page = requests.get(url)
        soup = BeautifulSoup(page.content,'html.parser')
        b = soup.findAll("h1")
        c = soup.findAll("div",{"class":"maincounter-number"})
        print("\n")
        print("Corona cases all over the world =>")
        for i in range(len(b)):
            print(b[i].text,c[i].text)
