Solve the following python programming problem given the following code:
@ tests.test 
def transaction_block() : 
    'Transaction using IoC.' 
    def block(lst) : 
        if lst : 
            lst.append (1) 
            return lst 
return [] 
test_cache = make_test_cache () 
    t = Transaction (block, 'key') 
    t (block) 
    assert (['interrupt', 1] == test_cache.get ('key') [1]) 

    
    

    Fix the buggy line: t = Transaction (block, 'key')
assistant
#Here is Python program to fix the buggy line: t = Transaction (block, 'key')
.

t = Transaction (test_cache, 'key')
