What is the Tkinter eval() function?

Question

I am currently building a calculator in Tkinter. I've been searching a few youtube videos to define a few functions and I came across this:

result = eval(self.string.get())

I understand that it is creating a new variable called result that holds the contents of string.get(), but I am unsure what eval() does.

Answer 1

This takes the string as an expression and determines its value. For instance, the string "3 + 5" would return 8.
