Question

我正在设计简单的代码，从总共5次给定的测试中确定学生的成绩为P（> 65％）或NP。到目前为止，这是我为此设计的代码，基于我的教授的要求，我希望将完全正确的结果显示为百分比，但是我一直在寻找正确的代码编写方法。 / p>

# Initialize Variables
studentName = "no name"
test1 = 0
test2 = 0
test3 = 0
test4 = 0
test5 = 0
totalScore = 0
finalGrade = 0
gradeMessage = None

# Print report title
print("\n Isabelle S - Programming Problem Two")

# Get user input data
studentName = input("Enter name of student ")
test1 = int(input("Enter test score 1: "))
test2 = int(input("Enter test score 2: "))
test3 = int(input("Enter test score 3: "))
test4 = int(input("Enter test score 4: "))
test5 = int(input("Enter test score 5: "))



# Compute values
totalScore = test1 +test2 +test3 + test4 + test5
finalGrade = totalScore / 100 * 100.0
if finalGrade >65:
 gradeMessage = "P"
else:
 gradeMessage = "NP"

# Print detail lines
print("\n Name of student: " , studentName )
print("Total Correct: " , totalScore )
print("Final Grade: " , gradeMessage )

Answer 1

要计算百分比，您需要除以最高总得分，然后将其乘以100得到百分比。

numberOfTests = 5
pointsPerTest = 100
finalGrade = totalScore/(numberOfTests*pointsPerTest) * 100

# Formatting like this allows all sorts of neat tricks, but for now
# it just lets us put that '%' sign after the number.
print("Final Grade percentage: {}%".format(finalGrade))

Answer 2

伊莎贝尔（Isabelle），需要知道每次测试中的最大可能点数（test1，test2，test3，test4和test5）。假设每个测试中的最高得分为 100 ，则可以稍微更改您的代码。可以使用finalGrade = totalScore / 100 * 100.0代替finalGrade = totalScore / 5。

以下为完整代码（具有上述更改）。 =）

from __future__ import division

# Initialize Variables
studentName = "no name"
test1 = 0
test2 = 0
test3 = 0
test4 = 0
test5 = 0
totalScore = 0
finalGrade = 0
gradeMessage = None

# Print report title
print("\n Isabelle Shankar - Programming Problem Two")

# Get user input data
studentName = input("Enter name of student ")
test1 = int(input("Enter test score 1: "))
test2 = int(input("Enter test score 2: "))
test3 = int(input("Enter test score 3: "))
test4 = int(input("Enter test score 4: "))
test5 = int(input("Enter test score 5: "))

# Compute values
totalScore = test1 +test2 +test3 + test4 + test5
finalGrade = totalScore / 5
print finalGrade
if finalGrade >65:
 gradeMessage = "P"
else:
 gradeMessage = "NP"

# Print detail lines
print("\n Name of student: " , studentName )
print("Total Correct: " , totalScore )
print("Final Grade: " , gradeMessage )

获取输出以在python中显示为百分比
