Python open()需要完整路径 [英] Python open() requires full path
问题描述
我正在编写一个脚本来读取一个csv文件. csv文件和脚本位于同一目录中.但是,当我尝试打开文件时,它会给我FileNotFoundError: [Errno 2] No such file or directory: 'zipcodes.csv'
.我用来读取文件的代码是
I am writing a script to read a csv file. The csv file and script lies in the same directory. But when I tried to open the file it gives me FileNotFoundError: [Errno 2] No such file or directory: 'zipcodes.csv'
. The code I used to read the file is
with open('zipcodes.csv', 'r') as zipcode_file:
reader = csv.DictReader(zipcode_file)
如果我提供文件的完整路径,它将起作用.为什么open()
需要文件的完整路径?
If I give the full path to the file, it will work. Why open()
requires full path of the file ?
推荐答案
我已经确定了问题所在.我在Visual Studio代码调试器上运行代码.我打开的根目录高于文件级别.当我打开相同的目录时,它起作用了.
I have identified the problem. I was running my code on Visual Studio Code debugger. The root directory I have opened was above the level of my file. When I opened the same directory, it worked.
