I am brand new to python and I've been set some work on dictionaries. I'd say I had a good go at it but it appears to be wrong. If you could explain where I went wrong and maybe provide the right answer that would be appreciated and I'd understand it a bit more.
def list_uniqueness(the_list):
'''
Return a dictionary with two key-value pairs:
1. The key 'list_length' stores the length of the_list as its value.
2. The key 'unique_items' stores the number of unique items in the_list as its value.
Arguments
the_list: A list
Examples
l = [1, 2, 2, 4]
dictionary = list_uniqueness(l)
print(dictionary['list_length']) # prints 4
print(dictionary['unique_items']) # prints 3
'''
# ====================================
# Do not change the code before this
# CODE1: Write code that will create the required dictionary
dictionary =
# ====================================
# Do not change the code after this
return dictionary
if __name__ == '__main__':
l = [1, 2, 2, 4]
dictionary = list_uniqueness(l)
print(dictionary['list_length'])
print(dictionary['unique_items'])My attempt at this challenge was: dictionary {list_length, unique_items}
list_length = len(l)
a_set = set(l)
unique_items = len(a_set)
