I am working on correcting the steering angle. Steps: 1) Filter the data based on backstretchend and backstretchstart of a race track 2) Calculate the mean of existing values by per car 3) Calculate the difference between the mean calculated per car and the actual values of steering in collected data 4) Calculate the mean of this difference
I have filtered and have calculated mean on overall column
Sample data:
car lap steering
00 20 10
00 21 -12
00 22 8
00 21 9
1 20 2
1 21 3
1 21 -9
1 22 8
Code:
backstretchstart = 0.5
backstretchend = 0.59
#Step 1: Filter the data based on backstretchend and backstretchstart of a race track
df = df.query('corrected_lap__frac > 0.50 & corrected_lap__frac < 0.59')
avgsteerback = df["steering"].mean()
df["steering_correct"] = df["steering"] - avgsteerback
avgsteer = df["steering_correct"].mean()
if avgsteer <= 0 and avgsteer != (np.isnan(avgsteer)):
df["steering_correct"] = df["steering_correct"] * - 1

I frequently want a dictionary mapping keys to consecutive IDs so I do the following:
The 'drain' event fires when the 'write()' method returns false according to Nodejs
The problem is that in node express server side i set a cookie to store some data ,in react i can view the data from the cookie set by server but in react-native i can't use cookie ,not a good solutionWhat would you recommend me to store the data in from server...
