Lets break apart this command $currentuserid = Get-WmiObject -Class win32_computersystem -ComputerName $workstation | Select-Object -ExpandProperty Username In powershell $ is the identifier for a variable. This means $currentuserid will equal the output of the last command in the pipe, In this case Select-Object. Also in powershell -whatever after a command is a parameter. The | … Read more

Your code in LocationFilter make no sense at all. ParticularEntries.Select(pg => pg.Region.Location == _selectedLocation); It returns an IEnumerable<bool> but it is never assigned. If you want to filter, you have to use Where. But even if you change your code to ParticularEntries = ParticularEntries.Where(pg => pg.Region.Location == _selectedLocation); you will see a change, but you … Read more

How would you attempt write an empty range? let someRange = … ?? That doesn’t make much sense, and if you specify either the upper or lower bound, … Read more
The solution is to pass the function as a lambda: from Tkinter import * root =Tk() def callback(parameter): print parameter button = Button(root, text=”Button”, command=lambda: callback(1)) button.pack() root.mainloop() Also, as @nbro already correctly pointed out, the button attribute is command, not function. 1 solved Tkinter Function attached to Button executed immediately [duplicate]
The Taylor series for the sin function is straightforward to implement. Note that any reference which gives a Taylor series for a trigonometric function will assume the input is in radians, unless specified otherwise. PI = 3.141592653589793238462643383 def sin_taylor_series(x, terms=9): # map x into the range -PI/2 to PI/2 for greatest accuracy x %= 2*PI … Read more
