Question

Can someone tell me how to do this question in python.
Question:
What is the output of this code?
a = ‘b’
b = {a: ‘a’, ‘a’: a}
print(b[a])

Answer 1

a = 'b'
b = {a:'a' , 'a':a}
but a = 'b'
this basically means the key a='b' has the value 'a'
and the key 'a' has the value 'b'
b = { 'b' : 'a' , 'a' : 'b' }
now print the value of the key a='b' in the dictionary named b , which is 'a'
