var = 3 string = “var” print(eval(string)) #3 Use of eval() is disadvised though is it’s vulnerable to attacks if you take a user input. Try and use a dictionary. var = 3 string = “var” my_dict = {“var”: var} pring(my_dict[string]) #3

ikon beth you appear to have demonstrated the same misunderstanding of the question as those who downvoted it.

See my answer above. To put it another way. If your variable string = “var”, and your variable var = 3, how do you print the value of the variable var only from using the variable string?
