Predict the output:

fruit = {}
L1 = ['Apple', 'banana', 'apple'] 
for index in L1 :
  if index in fruit: 
    fruit[index] += 1
  else :
    fruit[index] = 1
print(len(fruit))
print(fruit)

Predict the output:

arr = {}
arr[1] = 1 
arr['1'] = 2 
arr[1] += 1 
sum = 0
for k in arr:
  sum += arr[k]
print(sum)

Predict the output

a = {'a':1, 'b':2, 'c':3}
print(a['a','b'])

Find the error/output. Consider below given two sets of codes. Which one will produce an error? Also, predict the output produced by the correct code.

(a)

box = {}
jars = {'Jam' :4}
crates = {}	
box['biscuit'] = 1	
box['cake'] = 3	
crates['box'] = box	
crates['jars'] = jars	
print(len(crates[box]))

(b)

box = {}
jars = {'Jam' :4}
crates = {}	
box['biscuit'] = 1	
box['cake'] = 3	
crates['box'] = box	
crates['jars'] = jars	
print(len(crates['box']))
