Python Practice

Common Question Types

1. Algorithm Implementation

Example: "Write a function that finds the largest number in a list"

python

def find_largest(numbers):
    largest = numbers[0]
    for num in numbers:
        if num > largest:
            largest = num
    return largest

2. String Manipulation

Example: "Write a function that counts vowels in a string"

python

def count_vowels(text):
    vowels = "aeiouAEIOU"
    count = 0
    for char in text:
        if char in vowels:
            count += 1
    return count

3. Data Structure Operations

Example: "Create a dictionary from two lists (keys and values)"

python

def create_dict(keys, values):
    result = {}
    for i in range(len(keys)):
        result[keys[i]] = values[i]
    return result

4. List Comprehensions

Example: "Create a list of even numbers from 1 to 20"

python

evens = [x for x in range(1, 21) if x % 2 == 0]

Python Tips

Before Writing Code:

Read the question twice
Identify inputs and outputs
Plan your approach
Consider edge cases

While Coding:

Use meaningful variable names
Comment complex logic
Follow proper indentation
Test as you go

Common Mistakes to Avoid:

Forgetting to return values
Off-by-one errors in loops
Incorrect indentation
Not handling edge cases
Using = instead of ==

SQL Practice

Common Question Types

1. Basic SELECT

Example: "Select all students from the Students table"

sql

SELECT * FROM Students;

2. Filtering with WHERE

Example: "Select students with grades above 80"

sql

SELECT name, grade
FROM Students
WHERE grade > 80;

3. JOINs

Example: "List all students and their enrolled courses"

sql

SELECT Students.name, Courses.course_name
FROM Students
INNER JOIN Enrollments ON Students.id = Enrollments.student_id
INNER JOIN Courses ON Enrollments.course_id = Courses.id;

4. Aggregate Functions

Example: "Count the number of students in each course"

sql

SELECT course_id, COUNT(*) as student_count
FROM Enrollments
GROUP BY course_id;

5. Subqueries

Example: "Find students who scored higher than average"

sql

SELECT name, grade
FROM Students
WHERE grade > (SELECT AVG(grade) FROM Students);

SQL Tips

Before Writing Query:

Review the database schema
Identify which tables you need
Determine relationships between tables
Plan your joins

While Writing:

Use proper capitalization (convention)
Indent for readability
Use aliases for clarity
Test incrementally

Common Mistakes to Avoid:

Missing JOIN conditions
Wrong join type (INNER vs LEFT)
Forgetting GROUP BY with aggregates
Incorrect WHERE clause logic
Missing semicolons

Database Schema Reference

Most questions will include a schema description like:

Students Table:

id (INT, Primary Key)
name (VARCHAR)
grade (INT)
class_id (INT, Foreign Key)

Classes Table:

id (INT, Primary Key)
class_name (VARCHAR)
teacher (VARCHAR)

Understanding Schema:

Primary Key: Unique identifier
Foreign Key: Links to another table
Data Types: INT, VARCHAR, DATE, etc.

Example Questions

Python Example (Medium Difficulty - 8 marks)

Question: Write a function calculate_average(marks) that takes a list of student marks and returns the average, rounded to 2 decimal places. If the list is empty, return 0.

Sample Input: [85, 92, 78, 88, 95]Expected Output: 87.6

Sample Solution:

python

def calculate_average(marks):
    if len(marks) == 0:
        return 0
    total = sum(marks)
    average = total / len(marks)
    return round(average, 2)

# Test
print(calculate_average([85, 92, 78, 88, 95]))  # Output: 87.6

SQL Example (Medium Difficulty - 6 marks)

Question: Write a query to find all courses with more than 10 enrolled students, showing the course name and student count, ordered by student count (highest first).

Tables:

Courses (id, course_name)
Enrollments (id, student_id, course_id)

Sample Solution:

sql

SELECT c.course_name, COUNT(e.student_id) as student_count
FROM Courses c
INNER JOIN Enrollments e ON c.id = e.course_id
GROUP BY c.course_name
HAVING COUNT(e.student_id) > 10
ORDER BY student_count DESC;

Common Errors and Fixes

Python

Error: IndentationErrorFix: Ensure consistent use of spaces (4 spaces per level)

Error: NameError: name 'x' is not definedFix: Check variable spelling and scope

Error: IndexError: list index out of rangeFix: Check list length before accessing indices

Error: TypeError: unsupported operand type(s)Fix: Ensure compatible data types in operations

SQL

Error: Unknown column 'x' in 'field list'Fix: Check column names and table schema

Error: Syntax error near 'X'Fix: Review SQL syntax, check for missing keywords

Error: Column 'x' in field list is ambiguousFix: Use table aliases (e.g., Students.id)

Error: Every derived table must have its own aliasFix: Add alias to subqueries
