 Eventually, the \python\ interpreter could free the corresponding memory to use it for something else.

+Of course, we can have multiple variables.
 The command \pythonil{float_var = 3.5} creates a variable named \pythonil{float_var}.
 It also allocates a piece of memory, writes the floating point value \pythonil{3.5} into it, and lets \pythonil{float_var} point to that piece of memory, as illustrated in \cref{fig:variable:assignment3}.
 We can use this variable in an \pgls{fstring}\pythonIdx{f-string}\pythonIdx{str!f} as well:

+In \python, we can assign values to multiple variables at once~(of course, always exactly one value to one variable).
 In this case, we separate both the variable names and the values with commas.
 The first line~\pythonil{a, b = 5, 10}\pythonIdx{=!multiple}\pythonIdx{,} in \cref{lst:variables:multi_and_swap} is equivalent to the two lines~\pythonil{a = 5} and~\pythonil{b = 10}.
 It assigns the value~\pythonil{5} to the variable~\pythonil{a} and the value~\pythonil{10} to the variable~\pythonil{b}.

+A first step to avoiding any type-related errors in programs is, of course, careful programming.
 The second step is to use tools that check whether your program code contains ambiguities or errors.
 In languages like \pgls{C} and \pgls{Java}, the compiler will take care of that for you to a some extend, because these languages are statically and strongly typed.
