✅ Solution — Python Intermediate Task (Part 2)

Here’s a clean, Pythonic solution using filtering and lambda expressions:

def above_average(numbers):
avg = sum(numbers) / len(numbers)
return list(filter(lambda x: x > avg, numbers))

numbers = [3, 10, 7, 14, 1, 9, 20]
print(above_average(numbers))

🔎 Why this works

Average is calculated once

filter() expresses intent clearly

lambda keeps logic inline

💡 Alternative solutions using list comprehensions are equally valid.

✅ Solution — Python Intermediate Task (Part 1)

Here’s a more advanced and functional-style solution using dictionary comprehension:

def count_words(words):
return {word: words.count(word) for word in set(words)}

words = ["apple", "banana", "apple", "orange", "banana", "apple"]
print(count_words(words))

🔎 Why this works

set(words) removes duplicates

words.count() maps each word to its frequency

Dictionary comprehension keeps the solution concise

⚠️ Note: This is elegant, but not optimal for very large lists — a good interview discussion point.

🐍 Python Intermediate Task (Part 2)

This task focuses on mapping, filtering, and numerical logic.

🔍 Task

You are given a list of numbers.

Your task is to:

Calculate the average of the list

Return a new list containing only numbers greater than the average

Assume the list is not empty.

📥 Example Input
numbers = [3, 10, 7, 14, 1, 9, 20]

📤 Expected Output
[10, 14, 20]

🧠 Challenge

Write a function that:

Uses functional or declarative style

Minimizes temporary variables

Is readable and efficient

🔥 Bonus: Solve it in a single expression.

🐍Python Intermediate Task (Part 1)

This task focuses on data aggregation, dictionaries, and Pythonic thinking.

🔍 Task

You are given a list of strings.

Your task is to:

Count how many times each string appears

Return the result as a dictionary

Keys = words, Values = frequency

📥 Example Input
words = ["apple", "banana", "apple", "orange", "banana", "apple"]

📤 Expected Output
{"apple": 3, "banana": 2, "orange": 1}

🧠 Challenge

Implement a function that:

Solves the task in a Pythonic way

Avoids explicit for loops if possible

Does NOT use collections.Counter

What is Test Strategy?
✅Test Strategy is a well-described document in software testing which clearly defines the exact software testing approach and testing objectives of the software application. Test document is an important document for QA teams which is derived from actual business requirements that guides the whole team about software testing approach and objectives for each activity in the software testing process.

A Test strategy answers all the questions like what you want to get done and how you are going to accomplish it, etc. Writing an effective Strategy document is a skill that a tester develops with experience. Testing strategy plan should be communicated with the entire team so that the team will be consistent on approach and responsibilities.

✅Test Plan Vs Test Strategy
There is great confusion about Test Plan and Test Strategy documents. A different organization has their unique processes and standards to manage these documents. For example, some organization include test strategy facts in Test Plan itself while some organization includes strategy as a subsection within the testing plan.
