Answer 1

Below is a screen shot of the python program to check indentation. Comments are given on every line explaining the code.

1 # QUESTION 1: 2 -with open("exam_file.txt","r") as f: #open file 3 C = 0 for line in f: #Loop line by line 5 C += 1 #increment by 1 6. if c % 2 != 0: #if odd lines, then enter 7 A print(line) 8 9 #QUESTION 2: 10 fout = open("question2.out", "a") #Open file to write 11 with open("exam_file.txt","r") as f: #open file 12 for line in f: #Loop line by line 13 words = line.strip().split() 14 for win words: #loop word by word 15 fout.write(w+"\n") #write to file 16 fout.close() 17 18 #QUESTION 3: 19 import re 20 line = "1. Hello Mr. President, I am Nathan D. Green and this is my friend Johan T. Popsicle" 21 li = re.findall(" [A-Z]\. ", line) #Regex matches "space"+"1 A-Z character"+" . character"+ "space" 22 for x in li: 23 print(x[1]) 24 25 #QUESTION 4: 26 import re 27 sentence = "I will join Jon Snow on his adventure to the North to find the Wildlings" 28 print(re.sub(r' [B-DF-HJ-NP-TV-Z] [^\s]*', ' BEEP ', sentence)) 29 30 #QUESTION 5: 31 inp = input("Enter one topping: ") 32 toppings = {'peperoni': True m'olives': False pineapple': True "sausage': False mjalapenos': False} 33 toppings[inp. lower()] = True 34 print("This pizza contains", end="") 35 for x, y in toppings.items(): 36 if y is True: 37 A print(x, end=", ") 38

Below is the output of the program:
Question 1 output:

1 2 exam_file.txt fedur this is line 1 this is line 2 this is line 3 this is line 4 3 4

this is line 1 this is line 3


Question 2 output:

#CODE STARTS HERE----------------

# QUESTION 1:
with open("exam_file.txt","r") as f: #open file
   c = 0
   for line in f: #Loop line by line
      c += 1 #increment by 1
      if c % 2 != 0: #if odd lines, then enter
         print(line)

#QUESTION 2:
fout = open("question2.out","a") #Open file to write
with open("exam_file.txt","r") as f: #open file
   for line in f: #Loop line by line
      words = line.strip().split()
      for w in words: #loop word by word
         fout.write(w+"\n") #write to file
fout.close()

#QUESTION 3:
import re
line = "1. Hello Mr. President, I am Nathan D. Green and this is my friend Johan T. Popsicle"
li = re.findall(" [A-Z]\. ", line) #Regex matches "space"+"1 A-Z character"+" . character"+ "space"
for x in li:
   print(x[1])

#QUESTION 4:
import re
sentence = "I will join Jon Snow on his adventure to the North to find the Wildlings"
print(re.sub(r' [B-DF-HJ-NP-TV-Z][^\s]*', ' BEEP ', sentence))

#QUESTION 5:
inp = input("Enter one topping: ")
toppings = {'peperoni':True,'olives':False,'pineapple':True,'sausage':False,'jalapenos':False}
toppings[inp.lower()] = True
print("This pizza contains ", end="")
for x, y in toppings.items():
   if y is True:
