[Solved] What is the benefit of using assigning a default value to a parameter in a function in python

It’s because when doing: def calc_tax(sales_total,tax_rate=0.04): print(sales_total * tax_rate) You can do: calc_tax(100) Then here tax_rate is an argument that’s assigned to a default value so can change it by: calc_tax(any thing here,any thing here) OR: calc_tax(any thing here,tax_rate=any thing here) So in the other-hand, this code: def calc_tax(sales_total): print(sales_total*0.04) Is is only able to … Read more

[Solved] Convert image to binary to apply Image Steganography [closed]

[Solved] eps estimation for DBSCAN by not using the already suggested algorithm in the Original research paper

Try using OPTICS algorithm, you won’t need to estimate eps in that. Also, I would suggest recursive regression, where you use the python’s best curve fit scipy.optimize.curve_fit to get best curve, and then find the rms error of all the points wrt the curve. Then remove ‘n’ percent of points, and recursively repeat this untill … Read more

[Solved] Javascript – What is wrong with my code?

Javascript works with pointer, so passing the array as a paramater will edit that array from where it was called. This should do the job : function queue(arr, item) { arr.push(item); return arr.shift(); } var myArr = [1,2,3,4]; console.log(“Before: ” + JSON.stringify(myArr)); console.log(queue(myArr, 1)); // Modify this line to test console.log(“After: ” + JSON.stringify(myArr)); 0 … Read more
