if-statement

问题 Is it possible to put multiple conditions inside a single if statement in Shopify Liquid? For example this is what I have: {% if product.type != "A" and product.type != "B" and product.type != "C" %} //do something {% endif %} The reason I'm wondering is because syntax highlighting stops after the first "and" operator , as if everything after that has incorrect syntax. 回答1: Your syntax is 100% valid and will work in Shopify {% if product.type != "A" and product.type != "B" and product.type !=

问题 I need to update several thousand X coordinates in BlueZone. I'm using VBA to enter key commands in BlueZone VT. Unfortunately, there is no "set cursor position" command, so I am limited to using "tabs" to put the cursor where it needs to go. At the coordinate updating screen there are two possibilities: 6 or 7 tabs depending on the presence of a 0 or not on the screen. For example: location 241054 has a 1 and needs 7 tabs, location 241051 has a 0 and needs 6 tabs to get to the X location

问题 I want to bind the Start_Button with 2 possible functions: If Choice_1_Button is clicked and then the Start_Button , the Start_Button should call foo1 . But when the user clicks Choice_2_Button then the same Start Button should call foo2 . Here is the code I currently have: from tkinter import * root=Tk() Choice_1_Button=Button(root, text='Choice 1', command=something) #what should it do?

问题 I have 2 tables with a 1:1 relation. I'm trying to select everything from table1 and table2 using PK from table1. I want to select everything from table1 and, IF table1 PK = table2 FK THEN (and, only THEN) select from table2. To make it short, I want to select from table1 even if the query result doesn't have any relation in table2. If it has, then select from table2 as well. Anyone know how to do this? 回答1: It's a left outer join select table1.*, table2.* from table1 left outer join table2

问题 I am creating a procedure that uses an if statement to perform a decision. I have four variables: Altitude , Velocity , Angle and Temperature . The procedure is as follows: procedure Test3 is begin if (Integer(Status_System.Altitude_Measured)) >= Critical_Altitude and (Integer(Status_System.Velocity_Measured)) >= Critical_Velocity and (Integer(Status_System.Angle_Measured)) >= Critical_Angle and (Integer(Status_System.Temperature_Measured)) >= Critical_Temperature then DT_Put ("message 1");

问题 I start from the following question to seek generalization properties: if statement with dates in R df <- data.frame(date = as.Date(c("16.04.2015", "04.08.2014", "11.09.2013", "20.11.2015", "04.04.2014"), '%d.%m.%Y')) I want to identify all the dates between 07-15 (%m-%d) and 12-31, e.g. > date value > 16.04.2015 0 > 04.08.2014 1 > 11.09.2013 1 > 20.11.2015 1 > 04.04.2014 0 My solution is based on a solution by @rawr posted in the above question: Function for the interval: `%between%` <-

问题 I am trying to get a hit on my if-statement. I fetch qDiff (integer32) from the Core Data db and everything works except get a hit on the if-statements: NSString *diff; NSArray *fetchedObjects = [qContext executeFetchRequest:fetchRequest error:&error]; for (NSManagedObject *info in fetchedObjects) { NSLog(@"idQ: %@", [info valueForKey:@"idQ"]); NSLog(@"qDiff: %@", [info valueForKey:@"qDiff"]); //<<<<<<<<<Print correct number diff = [info valueForKey:@"qDiff"]; NSLog(@"diff: %@", diff); //<<<<

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . I need to analyze a string in JAVA to find out if it has both letters and numbers. So this is what I have so far. The variable pass is a String of maximum 8 characters/numbers that is inputted by the user. if
