>>> sum(i*i for i in range(10)) # sum of squares 285 >>> xvec = [10, 20, 30] >>> yvec = [7, 5, 3] >>> sum(x*y for x,y in zip(xvec, yvec)) # dot product 260 >>> from math import pi, sin >>> sine_table = {x: sin(x*pi/180) for x in range(0, ...
In this example, we import themathmodule and use itssqrtandsinfunctions to calculate the square root of 25 and the sine of pi/2, respectively. You can also import specific functions or variables from a module using thefromkeyword. For example: ...
(Python) You know that the Taylor Series for sin x is sum_k=0 ^infty (-1)^k x^2k+1 (2k+1)! . We can truncate the series to get an approximation for sin x as follows: sin x = x - x^3 3! + x^5 5! Create a program that calculate and print the monthly paycheck for ...
You can learn to program using any high-level programming language such as Python, Java, C++, or C#. Once you know how to program in one language, it is easy to pick up other languages, because the basic techniques for writing programs are the same. So what are the benefits of ...
