loops

问题 I am trying to use a loop for iterating through two lists. Unfortunately, the second for loop does not work: it only checks the first item within the list, but not with rest. Could you please tell me why? Thanks Lists: low_cars_engines=['Audi', 'Bentley', 'Bugatti', 'Porsche', 'Skoda'] low_planes_engines=['Pratt & Whitney','Rolls-Royce','GE Aviation'] I would like to add two more columns (Cars and Planes) to my original dataset based on if statements: if an object from list 'Engine to check'

问题 I'm trying to get the previous value for a certain calculation in the same loop. As I've highlighted in the code. I'm not sure if that's possible or unsure about how to go about it. start_year = 2001 year_list = list(range(2000, start_year + 1, 1)) month_day = [('JAN', 31), ('FEB', 28), ('MARCH', 31), ('APRIL', 30), ('MAY', 31), ('JUNE', 30), ('JULY', 31), ('AUG', 31), ('SEPT', 30), ('OCT', 31), ('NOV', 30), ('DEC', 31)] r_no ={2000: {'JAN': 705, 'FEB': 705, 'MARCH': 705, 'APRIL': 705, 'MAY':

问题 I would like to make this simplified so that I can control how many nested for loops there are. Essentially this would be 3 for d1 in ['left','right','up','down']: for d2 in CreateDirectionList(d1): for d3 in CreateDirectionList(d2): #Do something with list [d1, d2, d3] return False and 4 would be for d1 in ['left','right','up','down']: for d2 in CreateDirectionList(d1): for d3 in CreateDirectionList(d2): for d4 in CreateDirectionList(d3): #Do something with list [d1, d2, d3, d4] return False

问题 hope someone can help i have this code bellow working fine because i determined the range and exactly gave A1 numeric value as loop counter and starting point. Private Sub Worksheet_Change(ByVal Target As Range) If (Range("A1") <> "") And (IsNumeric(Range("A1"))) And (Range("A1") > 0) Then Dim X As Integer If Not Intersect(Target, Range("A1")) Is Nothing Then For X = 1 To Range("A1").Value Sheet4.Range("b" & X).Value = Range("A1").Value Next X MsgBox "done" Else End If Else MsgBox "no numeric

问题 I have refocused my questions and have tried to be as specific as possible. below, I also include code I have used so far; (1) When pulling data from SQL, my time is in a mixed format that contains a letter which is hard to work with. To avoid issues with that, i tried to apply; df.time=pd.to_timedelta(df.time, unit='ms'), which is fine by dont know how to extract the hours and minutes. Example;2019.11.22D01:18:00.01000, i just need to have column 'time' in following format; '01:18:00.01000'.
