Answer:
I am going to use the Python programming language to answer this. The source code is given below:
print("Enter your tweet here")
user_tweet = input()
decoded_tweet = user_tweet.replace('TTYL', 'talk to you later')
print("This is the decoded tweet: ")
print(decoded_tweet)
Explanation:
In the program the replace() module was used to replace 'TTYL' with 'talk to you later.'
Attached is the screenshot of the output.
Answer:-
(10111.001)₂
Explanation:
To convert a decimal number to a binary number we have to constantly divide the decimal number by 2 till the decimal number becomes zero and the binary number is writing the remainders in reverse order of obtaining them on each division.
Hence the binary number is 10111.001
To convert binary to hexa decimal we to make a group 4 binary bits starting from the decimal and moving outwards if the last group is not of 4 then add respective 0's and write the corresponding hexa decimal number.
<u>0001</u> <u>0111</u> . <u>0010</u>
1 7 2
Hence the hexadecimal number is 17.2
Answer:
In Python:
import os.path
from os import path
fname = input("Filename: ")
if path.exists(fname):
with open(fname) as file_in:
lines = []
for line in file_in:
lines.append(line.rstrip('\n'))
f = open("stat.txt","r+")
f.truncate(0)
f = open("stat.txt", "a")
f.write("Names\tTotal\tSubjects\tAverage\n")
for i in range(len(lines)):
rowsum = 0; count = 0
nm = lines[i].split()
for j in nm:
if (j.isdecimal()):
count+=1
rowsum+=int(j)
average = rowsum/count
f.write(nm[0]+"\t %3d\t %2d\t\t %.2f\n" % (rowsum, count, average))
f.close()
else:
print("File does not exist")
