Which of the following statements is false? $(4\mathrm{.}2\mathrm{.}3)$

Function calls can be embedded in expressions.

The following return statement first terminates the function, then squares number and gives the result back to the caller:

return number $**2$

The following code calls square first, then print displays the result:

print$(\text{'}$The square of $7$ is$\text{'},$ square$(7))$

Executing a return statement without an expression terminates the function and implicitly returns the value None to the caller. When there's no return statement in a function, it implicitly returns the value None after executing the last statement in the function's block.
