conditional-statements

I have a pandas dataframe and I need to create a new column based on an if-else condition. This question already came up here multiple times (e.g., Creating a new column based on if-elif-else condition ). However, I cannot apply the proposed solution, since I also need to look up values in a list in order to check the condition. I cannot do this with the proposed solution, because I am not sure how I can access my lookup-list in the external function. My lookup-list would need to be global, which I want to avoid. I have the feeling there should be a better way to do this. Consider the

My code contains a lot of multiple if statements. Is there any other way to get rid of these statements. For example suppose I have the following conditions if(t1 >= 1 && t2 == 0 && t3 == 0) $('div.b_class').fadeIn(); if(t1 == 0 && t2 >= 1 && t3 == 0) $('div.c_class').fadeIn(); if(t1 == 0 && t2 == 0 && t3 == 1) $('div.d_class').fadeIn(); if(t1 && t2 >= 1 && t3 == 0) $('div.b_class.c_class').fadeIn(); if(t1 && t3 >= 1&& t2 == 0) $('div.b_class.d_class').fadeIn(); Is there any way to simplify these statements? You could use a switch case structure with conditions inside like this : switch(true)

I was doing a simple calculator with the following code. Right now it executes perfectly. When I tried to change things around, however, it doesn't work. I used BOOL program to check whether to continue asking for input from the person or finish the program. If I change the expression of while statement to just (program) and change YES / NO in the program statements, why does the code fail to do what is inside the while ? // A simple printing calculator { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init] Calculator *deskCalc = [[Calculator alloc] init]; double value1; char operator

the line "if(arg2 & 1)" in C++(arg2 is DWORD) is equal to "if(arg2 & 1==0)" in C#(arg2 is Uint32),right? I am trying to translate a function from C++ to C#,but I get an error: Operator '&' cannot be applied to operands of type 'uint' and 'bool' I'd be also thankful if you could see further in the whole function for any other mistakes. C++ DWORD Func_X_4(DWORD arg1, DWORD arg2, DWORD arg3) { LARGE_INTEGER result = {1, 0}; LARGE_INTEGER temp1 = {0}; LARGE_INTEGER temp2 = {0}; LARGE_INTEGER temp3 = {0}; LARGE_INTEGER temp4 = {0}; for(int x = 0; x < 32; ++x) { if(arg2 & 1) { temp1.LowPart = arg3;

I came across a bizarre issue with PHPmailer (version 5.1) that I'm trying to work around. I've seen quite a bit of good feedback on here, so I thought I would give it a try. I've found that when I attempt to create a customized confirmation message with a conditional statement based on $mail->send() , I receive duplicate emails. I can duplicate it with the generic testemail.php script that comes with the phpmailer download. Here's the code: require '../class.phpmailer.php'; try { $mail = new PHPMailer(true); //New instance, with exceptions enabled $mail->SMTPDebug = 1; $mail->IsSMTP(); //

I have a quick question about which I did not find specific information on the web. I want to perform a Do...Loop Until loop, but I would like to insert more than one condition at the end. I would like to do: Do ' ...my code... Loop Until [Condition 1] And [Condition 2] And....And [Condition n]` Is this possible? Thank you very much in advance, Orlando The below example shows lazy evaluation implementation: Do ' some operations Select Case False Case Condition1 Case Condition2 Case Condition3 Case ConditionN Case Else Exit Do End Select Loop Such code allows to improve performance and speed up

I'm trying to figure out how to make multiple events happen with just one condition using .vbs. (Here I attempted to use the case statement.) Is there a such command, or do I have to rewrite the command for every line? (This is to be typed on notepad by having it already activated in previous lines of code.) msgbox("I was woundering how old you are.") age=inputbox("Type age here.",,"") Select Case age Case age>24 x=age-24 WshShell.SendKeys "I see you are "&x&" years older than me." WshShell.SendKeys "{ENTER}" Case age<24 x=24-age WshShell.SendKeys "I see you are "&x&" years younger than me."
