Question

Can someone fix this python program? I'm trying to do three things: Create a function that takes in a string as a parameter. Then create a dictionary of characters to integers, where the integer represents how many times the number of times the character appears in the word. Create a function that takes two lists as parameters and returns the elements they have in common of the two lists. Ask the user to create a list of numbers and keep asking them for entries until they enter a negative number. Then print the list and return the size of the list.

def getFreq(string):
    freq={}
    for i in string:
        freq[i]=freq.setdefault(i,0)+1
    return freq

def intersectLists(List1,List2):
    common=[]
    for i in List1:
        if i in List2:
            if i not in common:
                common.append(i)
    return common

def listOfNumbers():
    List=[]
    a=float(input('Enter number: '))
    while a>=0:
        List.append(a)
        a = float(input('Enter number: '))
    print(List)
    return len(List)
