Python Code Tracer
Determine the output of a code snippet by tracing variables line-by-line.
1: my_list = [10, 50, 20, 40, 30]
2: value = 0
3: for num in my_list:
4: if num > value:
5: value = num
6: print(value)
Trace Table:
| Line | Action | Variable `num` | Condition `num > value` | Variable `value` |
Understanding SQL INNER JOIN
Combine data from multiple tables. The INNER JOIN selects records that have matching values in both tables.
Students Table
| StudentID | Name |
|---|
| 1 | Amal |
| 2 | Bimal |
| 3 | Kamala |
Enrollments Table
| StudentID | Course |
|---|
| 1 | Maths |
| 2 | ICT |
| 3 | Physics |
The SQL Query:
SELECT Students.Name
FROM Students
INNER JOIN Enrollments
ON Students.StudentID = Enrollments.StudentID
WHERE Enrollments.Course = 'ICT';
