Consenting to these technologies will allow us and our partners to process personal data such as browsing behavior or unique IDs on this site. If the word key is just a variable, as you have mentioned then the main thing to note is that when you run a 'FOR LOOP' over a dictionary it runs through only the 'keys' and ignores the 'values'. In this scenario, use the .items() method, which returns each key-value pair as a two-value tuple.. To pre-split the tuple, specify two variables in your for loop so that the first tuple value (the key) and the second (the value) are stored in the first and second variables respectively. Then print each key-value pair within the loop: Alternatively, you can access the keys and values simultaneously using the items() method: Sometimes, you might want to output the result in reverse order. So the code you are looking for will be as followed: And if you were to use Python 2.x rather than 3.x, you would use this line in the for loop: I hope this has answered your question, just next time try to do a little more research, as there is probably another question answering this available.
