У меня проблема с кодом моего уни-проекта, особенно в разделе модуля turtle.Эта программа отображает оценки студентов, и мы должны показать гистограмму, используя модуль черепахи.Проблема, с которой я сталкиваюсь, заключается в том, что, хотя рабочая область черепахи появляется, курсор не двигается, чтобы нарисовать гистограмму.
Это код:
def menu():
allStudentsMarks = {}
while True:
userinput = input("Enter 1 to store student details \n"+
"Enter 2 to display student report \n"+
"Enter 3 to exit \n")
if userinput == "1":
enterMarks(allStudentsMarks)
elif userinput == "2":
displayReports(allStudentsMarks)
elif userinput == "3":
print("You have left the program. Thank you.")
break
def enterMarks(allStudentsMarks):
studentName = input("Please enter the student's name: ")
while True:
DFMarks = input("Please enter the marks from 0-20: ")
DFMarks = float(DFMarks)
if DFMarks >= 0 and DFMarks <= 20:
break
while True:
ProjectMarks = input("Please enter the marks from 0-30: ")
ProjectMarks = float(ProjectMarks)
if ProjectMarks >= 0 and ProjectMarks <= 30:
break
while True:
FinalMarks = input("Please enter the marks from 0-50: ")
FinalMarks = float(FinalMarks)
if FinalMarks >= 0 and FinalMarks <= 50:
break
marksList = [DFMarks, ProjectMarks, FinalMarks]
allStudentsMarks[studentName] = marksList
studentDetails = sum(marksList)
def getBelowAvgDFMarks(studentDetails):
marks = list(studentDetails.values())
dfTot = 0
dfLen = 0
for marksList in marks:
dfTot += marksList[0]
dfLen += 1
dfAvg = dfTot / dfLen
print("Displaying the student(s) whose DF marks are below the average of", dfAvg)
belowAvgDF = {}
for student in studentDetails:
if studentDetails[student][0] < dfAvg:
belowAvgDF[student] = studentDetails[student][0]
print(belowAvgDF)
return

projectLen = 0
for marksList in marks:

projectAvg = projectTot / projectLen
print("Displaying the student(s) whose project marks are below the average of", projectAvg)
belowAvgProject = {}
for student in studentDetails:
if studentDetails[student][1] < projectAvg:
belowAvgProject[student] = studentDetails[student][1]

belowAvgOverall[student] = sum(studentDetails[student])
print(belowAvgOverall)

Когда вы вводитезначение «6» («получить гистограмму итоговых оценок»), в меню «Отображение отчета о студентах» второго уровня должна быть показана гистограмма со значением итогового экзамена для каждого учащегося.
Спасибо.
