What is the output of the following snippet? dct = {‘one’: ‘two’, ‘three’: ‘one’, ‘two’: ‘three’} v = dct[‘three’] for k in range(len(dct)): v = dct[v] print(v)

dct = {'one': 'two', 'three': 'one', 'two': 'three'}
v = dct['three']
 
for k in range(len(dct)):
    v = dct[v]
 
print(v)

• (‘one’, ‘two’, ‘three’)
• one
• two
• three

Explanation: Let’s analyze the code:

• Line 1: the dct dictionary containing three key:value pairs is created
• Line 2: the v variable is created and assigned the dictionary value associated with the ‘three’ key, that is the string “one”
• Lines 4-5: the for loop performs three iterations (the length of the dct ctionary is 3):
• after k = 0 v = “two”
• after k = 1 v = “three”
• after k = 2 v = “one”
• the string “one” assigned to the v variable is then printed to the screen.
