10. 例子的另一种实现方法

OverallHighest = 0
OverallLowest = 100
OverallTotal = 0
Mark = 0
#for n in range(1,4):
#    print(n)

for Test in range(1, 5):
    SubjectHighest = 0
    SubjectLowest = 100
    SubjectTotal = 0

    if( Test ==1 ):
        SubjectName ="Maths"
    if( Test == 2 ):
        SubjectName ="Science"
    if( Test == 3 ):
        SubjectName ="English"
    if( Test == 4 ):
        SubjectName ="IT"

    for StudentNumber in range( 1, 4):

        print("Enter Student", StudentNumber,"‘s mark for",SubjectName)
        Mark = int(input ())
        if(Mark < 101 and Mark > -1):
  
            if (Mark < OverallLowest):
                OverallLowest = Mark
                
            if (Mark < SubjectLowest):
                SubjectLowest = Mark
            if (Mark > OverallHighest):
                OverallHighest = Mark
            if (Mark > SubjectHighest):
                SubjectHighest = Mark
            OverallTotal = OverallTotal + Mark
            SubjectTotal = SubjectTotal + Mark

        SubjectAverage = SubjectTotal/3
    print (SubjectName)
    print ("Average is", SubjectAverage)
    print ("Highest Mark is", SubjectHighest)
    print ("Lowest Mark is", SubjectLowest)

OverallAverage = OverallTotal/12
print ("Overall Average is", OverallAverage)
print ("Overall Highest Mark is", OverallHighest)
print ("Overall Lowest Mark is", OverallLowest)

其他的一些例子：：：：

11.

grade = 111
if grade == 'A':
    print("Excellent")
elif grade == 'B':
    print("Good")
elif grade == 'C':
    print("Average")
else:
    print("XXXX")

12.

Cost = 10**3 ##^
Price = Cost *2
Tax = Price*0.12
print(Cost,Price,Tax)
SellingPrice = Price + Tax
print(SellingPrice)
Gender = 'M   '+'hello'
Chosen = False #boolean zheshiyigezhushi
print(Gender,Chosen)
