I love python and I don&#x27;t like Julia at all.<p>But, I think judging a language (which claims math and scientific computing is it&#x27;s strongest point) by print screen performance is not fair.<p>And, the authors last example is a little bit misleading I think. The C code sets up registers and jumps to the main sprintf routine. I don&#x27;t know why didn&#x27;t he tell that routine&#x27;s instructions count...<p>Has any one counted?
