Add a print statement to the sqrt function defined in section 6.14 that prints out better each time it is calculated. Call your modified function with 25 as an argument and record the results.<br />
<br />
Here is 6.14:<br />
<br />
def sqrt(n):<br />
&nbsp; &nbsp; approx = n/2.0<br />
&nbsp; &nbsp; better = (approx + n/approx)/2.0<br />
&nbsp; &nbsp; while better != approx:<br />
&nbsp; &nbsp; &nbsp; &nbsp; approx = better<br />
&nbsp; &nbsp; &nbsp; &nbsp; better = (approx + n/approx)/2.0<br />
&nbsp; &nbsp; return approx<br />
<br />
I tried adding print better but it keeps saying better is not defined.

How do I add a print statement to this function so that It prints &quot;better&quot; everytime it is calculated?

Python is a widely used general-purpose, high-level programming language. Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in other languages. Python supports multiple programming paradigms, including object-oriented, imperative and functional programming or procedural styles. It features a dynamic type system and automatic memory management and has a large and comprehensive set of standard libraries, including NumPy, SciPy, Django, PyQuery, and PyLibrary.

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.
