Note that once the above if fails such that the below elif is tested,
you already know that curraverage>= 90 from the if above failed, so
on the elif below you really don't need to test if curraverage < 90.
elif curraverage >= 80 and curraverage < 90:
grade= "B"
lettergrades.append(grade)
elif curraverage >= 70 and curraverage < 80:
grade= "C"
lettergrades.append(grade)
elif curraverage < 70:
grade= "F"
lettergrades.append(grade)
You can also move the lettergrades.append(grade) outside the if tests.
Combining both simplifies this to:
if curraverage>= 90: grade="A"
elif curraverage >= 80: grade = "B"
elif curraverage >= 70: grade = "C"
elif curraverage >= 60: grade = "D"
else: grade = "F"
lettergrades.append(grade)
