The NumPy arccos() function is the trigonometric inverse cosine function so that, if y = cos(x), then x = arccos(y). If you apply it to a NumPy array, it performs the function element-wise. Arguments Type Description x array_like x-coordinate on the unit circle. For real arguments, the domain is [-1, 1]. out ndarray, None, or … Read more
Python is powerful — you can condense many algorithms into a single line of Python code. So the natural question arises: can you write a while loop in a single line of code? This article explores this mission-critical question in all detail. How to Write a While Loop in a Single Line of Python Code? … Read more
Problem: Given a collection. You want to create a new list based on all values in this collection. The code should run in a single line of code. How do you accomplish this? Do you need a lambda function? Example: Given an array a = [1, 2, 3, 4]. You need to create a second … Read more

Summary: The most Pythonic way to define a function in a single line is to (1) create an anonymous lambda function and (2) assign the function object to a variable name. You can then call the function by name just like any other regularly-defined function. For example, the statement f = lambda x: x+1 creates … Read more
The numpy.polymulx function multiplies the polynomial c with a value x which is the independent variable. Arguments Type Description c array_like or poly1d object The input polynomials to be multiplied The following table shows the return value of the function: Type Description Return Value ndarray or poly1d object The polynomial resulting from the multiplication of … Read more
The numpy.polymul function finds the product (multiplication) of two polynomials a1 and a2. As an input, use either poly1d objects or one-dimensional sequences of polynomial coefficients. If you use the latter, arange this polynomial sequence naturally from highest to lowest degree. Arguments Type Description a1, a2 array_like or poly1d object The input polynomials to be … Read more
