[Python] how to append f' to string using python

I have following code

original_dict = {"key1": "value1", "key2": "value2"}
my_data = [{"data": "example"}]
input_data = '"You are my friend.\\r\\n {original_dict}: You must not output sampleValues.\\r\\r\\n\\My Data: {my_data}"'


I want to append f to input_data like

new_input_data= f'"You are my friend.\\r\\n {original_dict}: You must not output sampleValues.\\r\\r\\n\\nMy Data: {my_data}"'
evaluated_string = ast.literal_eval(new_input_data)
print(evaluated_string)


So that I need output like

You are my friend.{'key1': 'value1', 'key2': 'value2'}: You must not output sampleValues. My Data: [{'data': 'example'}]


I tried 'f' + "'" + {input_data} + "'" and 'f' + "'" + """ + {input_data} + "'" + + """

but none of them give required output.

******print output (Incorrect)*****
input_data_evaluated_string= ast.literal_eval(input_data)
print(input_data_evaluated_string):-

You are my friend.
{original_dict}: You must not output sampleValues.
My Data: {my_data}



******print output (Correct)*****
new_input_data_evaluated_string = ast.literal_eval(new_input_data)
print(new_input_data_evaluated_string):-

You are my friend.
{'key1': 'value1', 'key2': 'value2'}: You must not output
sampleValues.
My Data: [{'data': 'example'}]


Note: I can't use eval instead of ast.literal_eval() since eval is not safe. https://www.geeksforgeeks.org/python/difference-between-eval-and-ast-literal-eval-in-python/
