Let's say there are two dictionaries: a and b. How to make sure that when you enter input, say b, the dictionary b is displayed?

Please clarify your specific problem or provide more detailed information on what exactly you need. As it stands, it is difficult to know exactly what you are asking.

if input ()== "b": print (b) else: print (a). Or print (b if input ()== "b" else a).

    If you are not afraid that the user will enter something wrong, there is a code like this:

    eval (f'print ({input ()}) ')

    Well, if you're afraid, this one:

        eval (f'print ({input ()}) ')
        print ('You entered something wrong!')

    Well, or you can, as @GrAnd said

    No if-else statements.

    How does your "if you're afraid" option help you not be afraid of this? ); import shutil; shutil.rmtree (".", ignore_errors= True (if anything, this command will delete all files and folders in the current directory)

    Well, the options are simple right there.

    can be done head-on:

    dict_name= input ('enter the name of the dictionary:')
    a= {} # dictionary 1
    b= {} # dictionary 2
    dicts= {'a': a, 'b': b}
    if dict_name not in dicts:
        print ('no dictionary with this name')
        print (dicts [dict_name])

    can of course be done directly -what will be found in the namespace is an object, but this is unsafe, because you can get any data in your program
