Help Please When i test this function i get error object of

Help Please! When i test this function i get error \"object of type \'function\' has no len()\", on line 35, if len(scoreList) >=1:

scoreList(Rack) takes as input a Rack which is a list of lower-case letters and returns a list of all of the words in the global Dictionary that can be made from those letters and the score for each one. Specifically, this function returns a list of lists, each of which contains a string that can be made from the Rack and its Scrabble score. Here are some examples using the tiny Dictionary above:

scrabbleScores = [ [\"a\", 1], [\"b\", 3], [\"c\", 3], [\"d\", 2], [\"e\", 1], [\"f\", 4],
[\"g\", 2], [\"h\", 4], [\"i\", 1], [\"j\", 8], [\"k\", 5], [\"l\", 1],
[\"m\", 3], [\"n\", 1], [\"o\", 1], [\"p\", 3], [\"q\", 10], [\"r\", 1],
[\"s\", 1], [\"t\", 1], [\"u\", 1], [\"v\", 4], [\"w\", 4], [\"x\", 8],
[\"y\", 4], [\"z\", 10] ]

Dictionary = [\"a\", \"am\", \"at\", \"apple\", \"bat\", \"bar\", \"babble\", \"can\", \"foo\", \"spam\", \"spammy\", \"zzyzva\"]

def letterScore(letter, scoreList):
for i in scoreList:
if i[0] == letter: #if letter in score[0]
return i[1] #return value[0][1]   

def wordScore(S, scoreList):
di = convertToDict(scoreList) #convert to dictionary
if (len(S) ==1): #base condition
return di[S[0]] #return score of first element
else:
return di[S[0]]+wordScore(S[1:],di) # if len of list is greater than
#1, call the function with list
#elements from 1 to remaining

def convertToDict(list):
if(type(list)==dict): # if type of passed element is dict
return list
di = {}
for i in list: # For each element in list
di[i[0]] = i[1] # add it to dict
return di

def scoreList(rack):
if len(scoreList) >=1:
return scoreList
for i in scoreList:
for j in dict:
L = [scoreList(rack-1)]
scoreList(rack-1)
return L

Solution

Hey, Here you are defining a function \"scoreList\" with rack as a argument.

When you are calculating length of you have to pass \"rack\" to len.

But here you are doing with function instead of rack array variable.

Check with this, len(rack).
