The question asks which statement about f-strings is false, and you’re given one proposed option but no list of alternatives to compare against.

Option provided: 'Replacement-text expressions may contain values, variables or other expressions, such as calculations, but may not contain function calls.'

To analyze this, recall how f-strings work in Python: the expressions inside the braces {} are evaluated as Python expressions, which can include variables, literals, arithmetic, and function calls. For example, f'{len(s)}' or f'{compute_value(x, y)}' are perfectly valid and will embed the result of those expressions into the string. This means that function calls are allowed inside replacement-field expressions.

Therefore, the claim that replacement-text expressions may not contain function calls is false, because function calls are indeed permitted within f-strings. The rest of the statement—that they may contain values, variables or other expressions such as calculations—is generally true, since expressions can involve literals, variables, arithmetic, and other computable expressions.

However, since the problem only provides this single option and omits the list of other choices, we cannot compare this option to others to determine which ones are false or true in this context. Without the full set of answer options, we cannot definitively identify all false statements or confirm which one is intended as the false option.

What can be concluded from the given content is that the specific claim about disallowing function calls inside f-string replacement expressions is incorrect, because Python permits function calls within f-strings as part of the embedded expressions.

If you obtain the complete list of answer choices, you would compare each option against Python’s f-string semantics: verify which statements correctly describe what can appear inside the braces and which do not, noting that function calls are valid inside replacement expressions.
