python - Unable to convert to datetime using pd.to_datetime -

-

I am trying to read a CSV file and use it as a time frame to convert it into datafree I am CSV file of this type: 

  # on time CO_T1_AHU.01_CC_CTRV_CHW__SIG_STAT 0 NaN NaN% 1 Nain Nain cooling coil Hydronic Valves Status 2 2014-01-01 00:00:00 0 3 2014 - 01-01 01:00:00 0 4 2014-01-01 02:00:00 0 5 2014-01-01 03:00:00 0 6 2014-01-01 04:00:00 0  < / Pre> 
 I have read using this file: 
 
  df = pd.read_csv ('filepath / file.csv', sep = ';', parse_dates = [[0 , 1]]  
 
 produced this result: 
 
  #Date_Time FCO_T1_AHU.01_CC_CTRV_CHW__SIG_STAT 0 no, 1% Ninan cooling coil Hydronic valve position 2 2014-01 - 01 00:00:00 0 3 2014-01-01 01:00:00 0 4 2014-01-01 02:00:00 0 5 2014-01-01 03:00:00 0 6 2014-01-01 04:00:00 0  
 
 To change the string in datetime and continue to use it as an index: 
 
  pd.to_datetime (df.values ​​[,, 0]) df.set_index ([Df.column [0]], inplace = true)  
 
 get: 
 
  FCO_T1_AHU.01_CC_CTRV_CHW__SIG_STAT #Date_Time nan nan% nan nan Cooling Coil Hydronic valve position 2014-01-01 00:00:00 0 01-01-2010 01:00:00 0 01-01-2010 02:00:00 0 01-01-2014 03:00:00 2014-01-01 -01 04:00:00 0  
 
 However, pd.to_datetime Unable to convert to datetime. What is the way to find out? 
 
 Many thanks louis

string entry 'Nain Nain' to to_datetime Can not be changed by using , so replace it with an empty string so they can now convert to NaT : 

 : Df ['Date_Time']. ( 'Nan Nan', '', inplace = true) df out [122]: Date Time Index CO_T1_AHU.01_CC_CTRV_CHW__SIG_STAT 0 0% 1 1 Cooling Coil Hydronic Valves Status 2 2014-01-01 00:00:00 2 0 3 2014-01-01 01:00:00 3 4 2014-01-01 02:00:00 4 5 5/2014-01-01 03:00:00 5 0 6 2014-01-01 04:00:00 6 in [124]: Df [ 'Date_Time'] = pd.to_datetime (df [ 'Date_Time']) DF-out [124]: Date_Time I Ndex CO_T1_AHU.01_CC_CTRV_CHW__SIG_STAT 0 NaT 0% 1 NaT 1 Cooling coil Hydronic valve position 2 2014- 01-01 00:00:00 2 0 3 2014-01-01 01:00:00 3 4 2014-01-01 02: 00:00 4 5 5 2014-01-01 03:00:00 5:00 6 2014 -01-01 04:00:00 6 0

UPDATE

Actually if you just have coded = True is set if it is correct Pantrit becomes: 

  df [ 'Date_Time'] = pd.to_datetime (df [ 'Date_Time'], Corrs = true)

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
