"""
Mini Project: Student Result & Access System
Purpose: Apply control flow concepts using conditions, loops and boolean logic
Output: Evaluates students, assigns grades, and controls access rules

# -----------------------------
# 1. Project Data
# -----------------------------
students = [
    {"name": "Mark", "score": 85, "attendance": 90, "has_id": True},
    {"name": "Sara", "score": 58, "attendance": 80, "has_id": True},
    {"name": "Aaqid", "score": 92, "attendance": 70, "has_id": False},
    {"name": "Lina", "score": 76, "attendance": 88, "has_id": True}
]

# -----------------------------
# 2. Loop through students
# -----------------------------
for student in students:
    name = student["name"]
    score = student["score"]
    attendance = student["attendance"]
    has_id = student["has_id"]

    print("\nStudent:", name)

    # -----------------------------
    # 3. Grade evaluation (if-elif-else)
    # -----------------------------
    if score >= 90:
        grade = "A"
    elif score >= 75:
        grade = "B"
    elif score >= 60:
        grade = "C"
    else:
        grade = "F"

    print("Grade:", grade)

    # -----------------------------
    # 4. Pass / Fail logic (boolean logic)
    # -----------------------------
    if score >= 60 and attendance >= 75:
        print("Status: Passed")
    else:
        print("Status: Failed")

    # -----------------------------
    # 5. Nested condition (access control)
    # -----------------------------
    if score >= 60:
        if has_id:
            print("Certificate: Issued")
        else:
            print("Certificate: ID required")
    else:
        print("Certificate: Not eligible")

# -----------------------------
# 6. while loop example (admin check)
# -----------------------------
attempts = 3
password = "admin123"
user_input = ""

while attempts > 0:
    user_input = await input("\nEnter admin password: ")

    if user_input == password:
        print("Admin access granted.")
        break
    else:
        attempts -= 1
        print("Wrong password. Attempts left:", attempts)

if attempts == 0:
    print("Admin access locked.")

# 7. Notes
# -----------------------------
# 1. Uses for loops to process multiple records.
# 2. Uses if-elif-else for decision making.
# 3. Uses boolean logic (and / or / not).
# 4. Uses nested conditions for deeper checks.
# 5. Uses while loop with break for control.
# 6. This structure mirrors real-world systems.
