Python CSV Error: sequence expected

Python CSV Error: sequence expected

writer.writerow expects a sequence (a tuple or list) of values to write in a single row, with one value per column in that row. What you have given it instead is a single value. Your code really should look more like:

writer.writerow([tmp_STID, tmp_Times, tmp_T, tmp_RH])

and it looks to me like most of this code should be in a big loop, which runs once per station (and thus once per row).

---

dataCSV = open(ProgramCheck.csv, w) 
writer = csv.writer(dataCSV, dialect=excel)
writer.writerow([Station ID, Time, Temperature , Relative Humidity]) 

for line in inputData:
    tmp = line.split()

    tmp_STID = str(tmp[0])
    tmp_T = float(tmp[4]) 
    tmp_RH = float(tmp[3])
    tmp_Times = float(tmp[2])

    if tmp_T < 6.2 and tmp_RH > 60.0: 
        writer.writerow([tmp_STID, tmp_Times, tmp_T, tmp_RH])

file.close()

Right now it looks like you are trying to write just a string

  writer.writerow(variables)

will write the whole row

 tmp_STID = str(tmp[0])
    tmp_T = float(tmp[4]) 
    tmp_RH = float(tmp[3])
    tmp_Times = float(tmp[2])

inspect the variables list

[tmp_STID, tmp_T, tmp_RH, tmp_Time]

also it looks like you are opening up a new csv file for each iteration? Should that be out of the loop?

Well, try to think about what Python expect when you trying to use the writeROW method 🙂
Entering just one value wont work, because every value will be in a different row, which is probably not what you trying to do. Instead, you might get all the values that are somehow related to each other in one set.

For example: The temprature is 26C on 16:35 at the Washington train station, with the humidity of 85%. This will be represented as: [Washington, 16:35, 26, 85].
