It seems that the airtemp ends with a new line.似乎airtemp以新行结束。 Try this:尝试这个：
row = ['2014', '12', '31', '01', 'ADR', lat, lon, airtemp.strip()]

finally i got the answer hehehehehe.终于知道答案了呵呵呵呵。 the answer is adding delimiter='\\t',lineterminator='\\n' to writer = csv.writer(csvFile).writerow(row) so the code will be like this答案是添加delimiter='\\t',lineterminator='\\n'到writer = csv.writer(csvFile).writerow(row)所以代码会是这样的
airtemp = rootgrp.variables['Tair_f_inst'][0][0][0]
lon = rootgrp.variables['lon'][0]
lat = rootgrp.variables['lat'][0]
row = ['2014', '12', '31', '01', 'ADR', lat, lon, airtemp]
with open('D:\Python\gg.csv', 'a') as csvFile:
writer = csv.writer(csvFile, delimiter='\t',lineterminator='\n',).writerow(row)
csvFile.close()
and the csv from this和来自这个的csv
Year,Month,Date,Time,plant,latitude,longitude,airtemp

2014,12,31,01,ADR,-2.375,115.375,297.5257
2014,12,31,01,ADR,-2.375,115.375,297.5257

2014,12,31,01,ADR,-2.375,115.375,297.5257
will be like this会是这样
