Python Practice Exercises for New Learners

🔹 Exercise 1: Working with Lists

Write a program that:

• Creates a list of 5 numbers

• Adds a new number to the list

• Removes the second number

• Prints the list

🔹 Exercise 2: Conditions with Loops

Create a list of numbers from 1 to 10. Use a for loop to:

• Print whether each number is even or odd

🔹 Exercise 3: Tuple and Indexing

Create a tuple with the names of 4 fruits.

• Print the first and last fruit using indexing

• Loop through the tuple and print each fruit in uppercase

🔹 Exercise 4: Set Operations

Create two sets:

• set1 = {1, 2, 3, 4}

• set2 = {3, 4, 5, 6}

Then:

• Print the union of the sets

• Print the intersection

• Add 7 to set1

🔹 Exercise 5: Dictionary and Conditionals

Create a dictionary of student marks:

marks = {
    "Alice": 85,
    "Bob": 56,
    "Charlie": 72
}

Then:

• Print only students who passed (marks ≥ 60)

• Add a new student "Diana" with mark 90

• Print the average mark of all students

✅ Answers

✅ Exercise 1:

numbers = [10, 20, 30, 40, 50]
numbers.append(60)
del numbers[1]  # Removes the second element (20)
print(numbers)  # Output: [10, 30, 40, 50, 60]

✅ Exercise 2:

nums = list(range(1, 11))
for num in nums:
    if num % 2 == 0:
        print(num, "is even")
    else:
        print(num, "is odd")

✅ Exercise 3:

fruits = ("apple", "banana", "mango", "orange")
print(fruits[0])     # Output: apple
print(fruits[-1])    # Output: orange

for fruit in fruits:
    print(fruit.upper())

✅ Exercise 4:

set1 = {1, 2, 3, 4}
set2 = {3, 4, 5, 6}

print(set1 | set2)  # Union: {1, 2, 3, 4, 5, 6}
print(set1 & set2)  # Intersection: {3, 4}
set1.add(7)
print(set1)         # Output: {1, 2, 3, 4, 7}

✅ Exercise 5:

marks = {
    "Alice": 85,
    "Bob": 56,
    "Charlie": 72
}

for name, score in marks.items():
    if score >= 60:
        print(name, "passed with", score)

marks["Diana"] = 90

average = sum(marks.values()) / len(marks)
print("Average mark:", average)
