試圖打開外部文本文件在我的主文件

Question

我的代碼讀取從開始到結束：

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()

終端響應：

user@cu-cs-vm:~/Dropbox$ python3 recitation4.py 
Traceback (most recent call last): 
    File "recitation4.py", line 5, in <module> 
    fo = open(BoulderWeatherData.csv, "r") 
NameError: name 'BoulderWeatherData' is not defined 

我想知道什麼是錯的與文件im調用，它被完全調用，並在我的主文件相同的目錄中找到....我不明白爲什麼它需要定義時，所有即時消息正在調用它....

Answer 1

嘗試引用您的文件名，因爲它是一個字符串...

fo = open("BoulderWeatherData.csv", "r") 

Answer 2

fo = open("BoulderWeatherData.csv","r") 

我希望" "缺少，因爲它是一個字符串
