Q2:
List & Dict Comprehension (2 Marks)
Create a dictionary, with single line of code whose ,

keys are odd numbers till 99
values are square of its respective key.
#Sample output
{ 1: 1, 3: 9, 5: 25,...... }
From the created dictionary get the keys, whose values >= 3000


ANS:
# ditionary with odd keys and values as square of odd keys
my_dictionary = { i:i*i for i in range(1,100) if i%2 != 0 }
print(my_dictionary)

# list with keys of dictionary whose value is >= 3000
my_list = [k for k,v in my_dictionary.items() if v >= 3000]
print(my_list)

Q5:
Tuple to Dict (3 Marks)
Given a list of tuples, write a function to convert the tuples into Dictionary. 

Always use the first element of each tuple as key.
If there are duplicates in the keys, add the values as list
#Sample input
data = [('key1',9), ('key2',23),('key1','hello'), ('key3','Bilbo')]
​
#Sample output
{'key1': [9, 'hello'], 'key2': 23, 'key3': 'Bilbo'}


ANS:
data = [('key1',9), ('key2',23),('key1','hello'),('key3','Bilbo')]
keys = []
values = []
for index, tup in enumerate(data):
    if tup[0] in keys:
        i = keys.index(tup[0])
        temp = [values[i]]
        values[i] = temp
        values[i].append(tup[1])
    else:
        keys.append(tup[0])
        values.append(tup[1])
        
result = dict(zip(keys, values))
print(result)
