Program freezes

[FlamingoRider]

When my program enters the fearList() function it will sit at a blank line and I'm unable to enter anything.

 
myFears=[]
def firstFear():
    if len(myFears) < 1:
        print "You have not entered any fears yet. Please enter one now."
        fear=raw_input("What is a fear of yours?")
        myFears.append(fear)
        return
 
def fearList():
    Running = True
    print "Your current fears are", myFears
    toDo=raw_input("Do you want to delete a fear, add one, or leave? (del, add, lev)")
    while Running:
        if toDo =="add" "ADD" "Add":
            addFear=raw_input("What is your fear?")
            myFears.append(addFear)
        elif toDo == "del" "DEL" "Del":
            delFear=raw_input("What fear have you overcome?")
            myFears.remove(delFear)
            print "Fear has been deleted"
        elif toDo == "lev" "LEV" "Lev":
            print "Goodbye"
            Running = False
            break
        else:
             global toDo
 
firstFear()
fearList()
 
 

Thanks for the help.

Your code makes comparisons that will never return True, so it enters an infinite loop.

>>> todo = "add" "ADD" "Add"
>>> todo
'addADDAdd'
>>> if todo == "add" "ADD" "Add":
...     print 1
...     
1
>>> 

Try this:

if toDo in ["add", "ADD", "Add"]

or try Boxfish's suggestion to use string method lower() in your other thread.

O.K. I've been trying at this for awihle now and I think I'm about to lose it lol.

I can't figure a way to properly loop fearList() so the LEV sequence will work. I also can't get the DEL sequence to work. The only thing that looks like it works correctly is adding new fears.

Any insight will be of great relief.

myFears = []
def firstFear():
    print "You have not entered any fears yet. Please enter one now."
    print
    fear=str.upper(raw_input("What is a fear of yours?"))
    myFears.append(fear)
    return
 
def fearList():
    print
    toDo=str.upper(raw_input("Do you want to delete a fear, add one, or leave? (del, add, lev)"))
    print
    if toDo == "ADD":
        addFear=str.upper(raw_input("What is your fear?"))
        myFears.append(str.upper(addFear))
        print str.upper(addFear), "has been added to the list." 
        print myFears
        print
        return
    elif toDo == "DEL":
        delFear=str.upper(raw_input("What fear have you overcome?"))
        print str.upper(delFear), "has been deleted"        
        for i in myFear:
            if i == delFear:
                del myFear
            print myFears
            print
        else:
            print "That is not on the list"     
            print
    elif toDo == "LEV":
        print "Goodbye"
    else:
        pass
 
firstFear()
fearList()
 

Trying to delete gives an UnboundLocalError: local variable myFear referenced before assignment

[boxfish]

This line should give you the UnboundLocalError:
for i in myFear:
There is no list called myFear to loop through. Either use
for i in myFears:
or
for myFear in myFears:

But the following code won't delete anything from myFears

for myFear in myFears:
    if myFear == delFear:
        del myFear

because myFear is just a copy of one of the elements of myFears.

What you have to do is really ugly. You need to loop through all the list indices, not the list items. So:

for i in xrange(len(myFears)):
    if myFears[i] == delFear:
        del myFears[i]
        break

The break statement exits the for loop as soon as the fear is found, otherwise, with one of the items missing, the indices will go out of the bounds of the array.

As for leaving, you can use a break statement here too, to exit the while loop:

elif toDo == "LEV":
    print "Goodbye"
    break

I hope this helps. I know how frustrating it can be to learn a programming language.

Well that did it! It works perfectly now lol. Thanks so much for all the help. I didn't know about the xrange function, I'll have to look that up. And putting [i] after myFears, I wouldn't have thought about it. I have a lot more reading to do I guess :(
