Lists and tuples can be easily generated from strings depending on how you wish to split them. A primitive example: usr_inp = input() print(list(usr_inp)) print(tuple(usr_inp)) A dictionary is tricker. You can rely on literal_eval https://docs.python.org/3/library/ast.html#ast.literal_eval or just parse it yourself if you can be sure that the input string will always conform to how a dict is represented in Python. https://stackoverflow.com/questions/988228/convert-a-string-representation-of-a-dictionary-to-a-dictionary

On SL you can try the following way of getting the user to enter a dictionary in python. out_dct={i.strip():j.strip() for i,j in [tuple(k.split(':')) for k in input().split(',') ]} print(out_dct) Enter text on one line as: a : apple juice, b : banana juice , c : carrot juice https://code.sololearn.com/c6YFNWDMNm06/?ref=app

To show in SL how your code works you can use samples or random data.

mm not entirely sure what you mean, but you can use the exec function to execute python code based on input and string value (in this example I entered the value of “test” in input to create a list) createlist = input() + " = []" exec(createlist) #I entered “test” as input which created a list named test test.append("hi") print(test) however, I would assume this method should be avoided if at all possible...
