поэтому в основном я пытаюсь прочитать столбец из CSV-файла в массив, а затем выполнить вычисления с этим массивом.Я успешно получил массив 'rawSunlightData' из файла csv, но по какой-то причине каждый раз, когда я пытаюсь выбрать переменную из массива 'raySunlightData', я получаю сообщение об ошибке [Во время обработки вышеуказанного исключения произошло другое исключение] Я могу напечататьцелый rawSunlightData, но не может печатать отдельные значения, такие как rawSunlightData [0]
cleanSunlightData = []
rawSunlightData = pd.read_csv('Average daily sunlight per month.csv', header = None)
rawSunlightData = rawSunlightData.drop(rawSunlightData.columns[[0]], axis=1)
print(rawSunlightData[0])
i = 0
while i <= len(rawSunlightData):
arrayDivider = []
m = 0
while m < 12:
x = i + m
print(x)
m += 1
i += 12
сообщение об ошибке:
