Practical Examples (OCR Pseudocode & Python)

Example 1: Grade Calculator

OCR Pseudocode:

score = input("Enter score: ")
if score >= 70 then
    grade = "A"
elseif score >= 60 then
    grade = "B"
elseif score >= 50 then
    grade = "C"
elseif score >= 40 then
    grade = "D"
else
    grade = "U"
endif
print("Grade: " + grade)

Python Equivalent:

score = int(input("Enter score: "))
if score >= 70:
    grade = "A"
elif score >= 60:
    grade = "B"
elif score >= 50:
    grade = "C"
elif score >= 40:
    grade = "D"
else:
    grade = "U"
print("Grade:", grade)

Example 2: Login Validation

username = input("Username: ")
password = input("Password: ")
if username == "admin" AND password == "secret123" then
    print("Access granted")
    loggedIn = true
else
    print("Access denied")
    loggedIn = false
endif
