Why does a list append the same item everytime

Python

I have a generator which yields a new dictionary whenever called. Although despite the generator producing a new dictionary the list keeps appending the same dictionary over and over again. My code is like follows.

def dictionary_generator():
    dictionary = {}
    # I create a dictionary.
    ... 
    yield dictionary 

def my_function(var):
    my_list = []
    for i in range(var):
        my_list.append(next(dictionary_generator))
    return my_list

My generator yields the following dictionary for example,

{
'name': 'john',
'age': 26,
'work':'politician'
}
{
'name': 'tom',
'age': 34,
'work':'cricketer'
}
{
'name': 'jimmy',
'age': 99,
'work':'actor'
}

Although my list will look something like this

[
{
'name': 'jimmy',
'age': 99,
'work':'actor'
},
{
'name': 'jimmy',
'age': 99,
'work':'actor'
},
{
'name': 'jimmy',
'age': 99,
'work':'actor'
}
]

Note:
The code is simplified and narrowed to the lines of code where the bug exists

What I have tried:

I have tried different methods of appending the list but all worked as the same way as I described
