How can I solve this problem? Using a list comprehension - Read each entry in the string arrays into dictionary objects to create two lists of dictionaries - Iterate over the two lists, first_list and second_list one at a time and produce two new lists of dictionaries. - Call them first_dicts and second_dicts. - Print the first 2 entries in each list

You are most welcome! Thank you very much for the kind words! Stay curious and eager to learn! :) --- Best, A., The 365 Team

Hey Jaiswal, I think you actually offer an interesting problem in its own right, which is very nice. Would you mind expanding it a bit, maybe give a small example of what needs to be done? ---------------------------------------- To my mind, you have two lists of 'string' objects (which are first_list & second_list) and you want to use a list comprehension to produce a set of two dictionaries. If that is the case, I would assume the two dictionaries have the same key-value pairs, but swapped (this may not be the case; if you have something different in mind, do let us know by writing here again ;)). The following code does the trick: ---------------------------------------- I would also like to offer a brief explanation to the code. When you need to iterate two (or more) lists (or iterables, generally) simultaneously, you can always opt for the zip function. It produces tuples of size = the number of lists. When you write - ... for (first_str, second_str) in zip(first_list, second_list), you iterate over both lists, namely - first_str iterates over first_list and second_str iterates over second_list. To get dictionaries, you just need to place whatever you need in curly brackets {entry_1 : entry_2}. ---------------------------------------- Let us know if more clarification is needed or the problem is different (sorry for the misunderstanding, if that is the case). On a positive note, maybe the picture can help you get the result you are looking for. The code is a very popular way to iterate over two lists in a list comprehension. If you can adapt it to your needs,it would be wonderful. You can always drop a line to share a success story :) Regards, A., The 365 Team

Oh! so it was just removing the curly brackets! Thank you so much! May I call for your help again soon!

I would love to add that on my cheat sheets! Thank you so much! May I shoot another question here or should I post it as another question?

I'm just gonna post it here for now. Do tell me if I have made the wrong move! :D Suppose I have a Json file dummy.json. I would like to open it and read its contents into a string. Here is another phrasing: I want to open dummy.json and store the text it contain into a string variable called dummy_string. After that, I would like to print the first 500 characters of dummy_string. Here was my attempt: dummy_string = open('dummy.json','r') for char in dummy_string: print(char[0:500]) dummy_string.close() The problem I am encountering is that I am printing the first 500 entries instead of only the first 500 characters.

Also, following up the output of the list comprehension, How do i prove that the entries in the list is a dictionary? Here was my attempt:¨ type(products_dicts[0]) and it outputs: str

Hey Jaiswal, Of course, you can ask freely as you like, my only piece of advice is -- if you mark a question as resolved, it's better to post a new topic in the Q&A section. It's just a bit of organisation, also, think about other students having the same issues. Different questions can help them navigate their way better to the answers. ---------------------------- Now, on to the first question. You have a dummy.json file. A JSON is a special file format and Python comes with built-in tools to manipulate json files. This is where you need to decide do you work with dummy.json as a regular text file (including '{', '}', '[', ']', etc. as characters) or you need to work with it like you would with a json file. I will give a small example for both, then you will make your mind what you really need and adapt it to your situation. Reading from a text files is done with readlines() - see appropriate lecture on I/O operations with Python. Note that every time you read the file, you need to use seek(0) to return to the beginning if you wish to read again! ----------------------------- I attach ny code using a json file I got from https://jsonplaceholder.typicode.com/. My dummy.json is actually the 'comments' json file. I hope you will be able to reproduce the results and see that if you want to print the first 500 characters, there are minor changes you have to take care of. As for the list comprehension, use a print() statement to see what products_dicts[0] is. Maybe you need to change the indexing? ------------------------------------ Best regards, A., The 365 Team

Hey! What should be the indexing be? any suggestion? products_dicts[0] outputs a dictionary structured data, but if i check it's type type(products_dicts[0]), it says it's a 'str'

Hi, If products_dicts[0] has a set of quotes '...', this is still a string. I would assume you are reading from the json file, which consists of various dictionary-like entries. If you want to convert such a string to a dictionary, you can use dict(my_str), where my_str is the string in question. Otherwise, I would suggest looking up online the workflow with json files in python. Without knowing what you aim to achieve, we can only offer some general tips.Still, I think you can cast to dictionary and be able to proceed smoothly from there on. Regards, A. The 365 Team

Sure, we are always looking forward to interesting questions! Delighted to have helped!

Hey! I Referring to what you've said previously. This is indeed the problem if products_dicts[0] has a set of quotes '...', this is still a string. I would assume you are reading from the json file, which consists of various dictionary-like entries. If you want to convert such a string to a dictionary, you can use dict(my_str), where my_str is the string in question. here is my output: ['{"Username": "bkpn1412", "DOB": "31.07.1983", "State": "Oregon", "Reviewed": ["cea76118f6a9110a893de2b7654319c0"]}\n', '{"Username": "gqjs4414", "DOB": "27.07.1998", "State": "Massachusetts", "Reviewed": ["fa04fe6c0dd5189f54fe600838da43d3"]}\n'] It's from this one: reviewers_dicts = [rev for rev in reviewers_list] reviewers_dicts[:2] How do I make the outputs be dictionary entries instead of string?
