Im having trouble with my inputCheck statement. I need to be able to remove things from the list but they have to be on there. Thank you!

I tried to make a iputCheck variable that checks the list for the input to make sure it matches something in the list, but it all went downhill.

There were numerous mistakes in your code. Instead of pointing then all out I have fixed them and will allow you to figure it out on your own.

global classes
classes = []
    
print("Welcome to class registration!")
    
def printClasses():
    print("You are currently taking these courses: ")
    count = 1
    for item in classes:
        print('{}. {}'.format(count, item))
        count  = 1
    
while True:
    if(len(classes) < 5):
        course = str(input("What course(s) would you like to take?: \n"))
        classes  = course.split(",")
        for i in range(len(classes)):
            classes[i] = classes[i].strip().title()
        printClasses()
    elif (len(classes) > 5):
        removeClass = str(input("Please select a class to remove: \n"))
        classGone = removeClass.split(",")
        for item in classGone:
            i = str(item)
            if i.strip().title() in classes:
                classes.remove(i)
            else:
                print("Please select a class that exists...")
        printClasses()
    
    else:
        print("Done!")
        break

CodePudding user response：

Had a pretty hard time understanding what you meant but I think I got it. You want to check if the selected class for removal is in the list? If that's the case you can use the following code:

#The list
classes=["English","Math","Coding"]

##Asking what classes to remove
Class_To_Remove=input("What class do you want to remove?")

#Removing the classes and checking if they are
for x in classes:
    if Class_To_Remove.capitalize() in x:
        classes.remove(Class_To_Remove.capitalize())
        print("Class removed")
    else:
        print("Class isn't added")

If I understand everything correctly this will replace your:

    removeClass = input("Please select a class to remove: \n")
    removeClass = removeClass.title()
    removeClass = str(removeClass)
    removeClass = removeClass.strip()
    classGone = []
    classGone = removeClass.split(",")
    for i in range(len(classGone)):
        classGone[i] = classGone[i].strip()
    for item in classGone:
        removeClass = []
        inputCheck = classGone.count(removeClass)
        if inputCheck > 0:
            classes.remove(item)
        else:
             print("Please select a class that exists...")

For future reference try to only use the few lines you are having trouble with and explaining the problem more clear.

CodePudding user response：

I've been trying to understand this for some time. For the next one please be more clear. Since there's several mistakes on your code, I tried to make a solution that could work for you. Here it is!

global classes
classes = []

print("Welcome to class registration!")


def printClasses():
    print("You are currently taking these courses: ")
    for i in range(0, len(classes)):
        print(i 1, ".", classes[i])


control = True
while control:
    if(len(classes) < 5):
        course = str(input("What course(s) would you like to take?: \n"))
        classes  = course.split(",")
        for i in range(len(classes)):
            classes[i] = classes[i].strip().title()
        printClasses()
    elif (len(classes) >= 5):
        option = input("Do you want to remove a class?\n 1.Yes\n 2.No\n")
        if option == "1":
            classGone = []
            for i in range(1):
                removeClass = input("Please select a class to remove: \n")
                if (removeClass == classes[0] or
                    removeClass == classes[1] or
                    removeClass == classes[2] or
                    removeClass == classes[3] or
                        removeClass == classes[4]):
                    classes.remove(removeClass)
                    classGone.append(removeClass)
                    print("Classes removed are: ", classGone)
                    printClasses()
                    i  = 1
                    break
                else:
                    print("Please select a valid class")
        elif option == "2":
            print("Done!")
            break

Hope it works!
