试图打开外部文本文件在我的主文件

Question

我的代码读取从开始到结束：

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：

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 

我想知道什么是错的与文件im调用，它被完全调用，并在我的主文件相同的目录中找到....我不明白为什么它需要定义时，所有即时消息正在调用它....

Answer 1

尝试引用您的文件名，因为它是一个字符串...

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

Answer 2

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

我希望" "缺少，因为它是一个字符串
