# Method 2 (Python 3.9+)
merged_dict = dict1 | dict2

print(merged_dict)

4. How to find the intersection of two lists?

list1 = [1, 2, 3, 4]
list2 = [3, 4, 5, 6]

intersection = list(set(list1) & set(list2))
print(intersection)  # [3, 4]

5. How to generate a list of even numbers from 1 to 100?

even_numbers = [i for i in range(1, 101) if i % 2 == 0]
print(even_numbers)

6. How to find the longest word in a sentence?

def longest_word(sentence):
    words = sentence.split()
    return max(words, key=len)

print(longest_word("Python is a powerful language"))  # "powerful"

7. How to count the frequency of elements in a list?

from collections import Counter

my_list = [1, 2, 2, 3, 3, 3, 4]
frequency = Counter(my_list)
print(frequency)  # Counter({3: 3, 2: 2, 1: 1, 4: 1})

8. How to remove duplicates from a list while maintaining the order?

def remove_duplicates(lst):
    return list(dict.fromkeys(lst))

my_list = [1, 2, 2, 3, 4, 4, 5]
print(remove_duplicates(my_list))  # [1, 2, 3, 4, 5]

9. How to reverse a linked list in Python?

class Node:
    def __init__(self, data):
        self.data = data
        self.next = None

def reverse_linked_list(head):
    prev = None
    current = head
    while current:
        next_node = current.next
        current.next = prev
        prev = current
        current = next_node
    return prev

# Create linked list: 1 -> 2 -> 3
head = Node(1)
head.next = Node(2)
head.next.next = Node(3)

# Reverse and print the list
reversed_head = reverse_linked_list(head)
while reversed_head:
    print(reversed_head.data, end=" -> ")
    reversed_head = reversed_head.next

10. How to implement a simple binary search algorithm?

def binary_search(arr, target):
    low, high = 0, len(arr) - 1
    while low <= high:
        mid = (low + high) // 2
        if arr[mid] == target:
            return mid
        elif arr[mid] < target:
            low = mid + 1
        else:
            high = mid - 1
    return -1

print(binary_search([1, 2, 3, 4, 5, 6, 7], 4))  # 3

𝗗𝗮𝘁𝗮 𝗦𝗰𝗶𝗲𝗻𝗰𝗲 𝗿𝗼𝗮𝗱𝗺𝗮𝗽 𝘁𝗼 𝘀𝗵𝗮𝗽𝗲 𝘆𝗼𝘂𝗿 𝗰𝗮𝗿𝗲𝗲𝗿: 👇

-> 1. Learn the Language of Data
Start with Python or R. Learn how to write clean scripts, automate tasks, and manipulate data like a pro.

-> 2. Master Data Handling
Use Pandas, NumPy, and SQL. These are your weapons for data cleaning, transformation, and querying.
Garbage in = Garbage out. Always clean your data.

-> 3. Nail the Basics of Statistics & Probability
You can’t call yourself a data scientist if you don’t understand distributions, p-values, confidence intervals, and hypothesis testing.

-> 4. Exploratory Data Analysis (EDA)
Visualize the story behind the numbers with Matplotlib, Seaborn, and Plotly.
EDA is how you uncover hidden gold.

-> 5. Learn Machine Learning the Right Way

Start simple:

Linear Regression

Logistic Regression

Decision Trees
Then level up with Random Forest, XGBoost, and Neural Networks.


-> 6. Build Real Projects
Kaggle, personal projects, domain-specific problems—don’t just learn, apply.
Make a portfolio that speaks louder than your resume.

-> 7. Learn Deployment (Optional but Powerful)
Use Flask, Streamlit, or FastAPI to deploy your models.
Turn models into real-world applications.

-> 8. Sharpen Soft Skills
Storytelling, communication, and business acumen are just as important as technical skills.
Explain your insights like a leader.
