Answer:
A firewall is used to monitor and control incoming and outgoing (or in better terms, inbound and outbound) traffic in a network based on some pre-defined security rules set by either an individual or a business.
Now, using firewall to block outgoing packets that have source addresses which are not in an organization's address space means rejecting requests that, though originate from the organization's address space, are not in the organization's allowable address.
This is necessary and of utmost importance because even though an hacker (or simply an attacker) gains access into the organization's network, there is a limit to what harm they can do. If for example, they manage to get some malicious programs into the system's via network processes such as using infected e-mails or using a browser, they might also want to make some requests to the Internet to get some additional programs downloaded which altogether is harmful to the system. Disabling or blocking outgoing packets or traffic will stop this combined hazard from happening.

Answer:
def analyze_text(sentence):
count = 0
e_count = 0
for s in sentence:
s = s.lower()
if s.isalpha():
count += 1
if s == "e":
e_count += 1
return "The text contains " + str(count) + " alphabetic characters, of which " + str(e_count) + " (" + str(e_count*100/count) + "%) are ‘e’."
Explanation:
Create a function called analyze_text takes a string, sentence
Initialize the count and e_count variables as 0
Create a for loop that iterates through the sentence
Inside the loop, convert all letters to lowercase using lower() function. Check each character. If a character is a letter, increment the count by 1. If a character is "e", increment the e_count by 1.
Return the count and e_count in required format
