当我上传并尝试使用以下代码打开文件时,我收到此错误:

  

IOError:[Errno 2]没有这样的文件或目录

我的代码如下:

from google.colab import files

#upload file
uploaded = files.upload() 

# Open file
f = open(uploaded['small.txt'], 'r')

# Feed the file text into findall(); it returns a list of all the found strings
strings = re.findall(r'ne\w', f.read())

1 个答案:

答案 0 :(得分:0)

问题在于这一行:

f = open(uploaded['small.txt'], 'r')

使用uploaded = files.upload()上传文件时,实际文件内容存储在uploaded['small.txt']中,而不是路径中。

所以,我认为它应该修复错误,直接在正则表达式中使用uploaded['small.txt'],例如,

strings = re.findall(r'ne\w', uploaded['small.txt'])
