Is there a way to print a list when you have its name as a string?

Say we have the list l= [1,2,3] and the string s= 'l'. Is there a way to get s to print l?

it depends on in wich scope is the variable... if it's a global variable in the current module: print(global()[string_variable_name]) if it's a local variable: print(local()[string_variable_name]) if it's a variable in another module: import other_module print(getattr(other_module,string_variable_name))

another option instead of eval could be using a dictionary or a class. dictionary example: dict[‘I’] = [1,2,3] class example: class myClass(): pass myString = myClass() myString.I = [1,2,3]

eval == evil well, eval() works too, but should be avoided as could be used to do anything else (unsafe) if the string is given by untrusted user ^^

_dict = {"l" : [1,2,3,4]} s = "l" print(_dict[s]) This si the best way i just found for doing that, It works, because you can call a dictionary Index by string. For accesing a value from the list you just: _dict[s][value_index]

In any programming language the same pedagogy applies - iterate through the list and list the items 🌻
