Colab：打印上传的txt文件的所有行

Question

我正在使用以下方式将文件上传到 colab：

from google.colab import files
uploaded = files.upload()

然后我尝试读取上传文件中的所有行：

for line in uploaded:
    print(line)

但我得到的是文件名 text.txt 而不是它的行。

如何正确阅读？

谢谢

uploaded 对象是一个字典，其中包含文件名和每个上传文件的内容。

这里有一些代码循环遍历所有上传的文件，每个文件都尝试将内容读入一个行列表，然后打印出来。

from google.colab import files
uploaded = files.upload()   
for filename in uploaded.keys(): # get the name of each uploaded file
  print(filename)
  lines = uploaded[filename].splitlines() # split the contents into lines
  for line in lines:  # iterate over all lines
    print(line.decode('utf-8'))  # print the line (it needs to be decoded)
