Predict the output.

tuple_a = 'a', 'b'  
tuple_b = ('a',  'b')  
print (tuple_a == tuple_b)  

Find the error. Following code intends to create a tuple with three identical strings. But even after successfully executing following code (No error reported by Python), The len( ) returns a value different from 3. Why ?

tup1 = ('Mega') * 3 
print(len(tup1))

Predict the output.

x = (1, (2, (3, (4,))))  
print(len(x))  
print( x[1][0] )   
print( 2 in x )  
y = (1, (2, (3,), 4), 5)  
print( len(y) )   
print( len(y[1]))  
print( y[2] + 50 )
z = (2, (1, (2, ), 1), 1)
print( z[z[z[0]]])

What will the following code produce ?

Tup1 = (1,) * 3
Tup1[0] = 2 
print(Tup1)
