尝试打开要在我的主文件中读取的外部文本文件

Question

我的代码开始结束：

fo = open(BoulderWeatherData.csv, "r")
days=0
precip=0
lines = fo.readline()
listofpercip = []

for lines in fo:
    days = days +1
    splitting = line.split(",")
    precip = precip + float(splitting[4])
    listofpercip.append(spliting[4])
avg = round(listpercip / days, 2)

print ("the average rainfall is ", average)
print ("the max amount of rain for one day is:", max(listofpercip))

fname.close()

终端响应：

Traceback (most recent call last):
  File "recitation4.py", line 5, in <module>
    fo = open(BoulderWeatherData.csv, "r")
NameError: name 'BoulderWeatherData' is not defined
