How to open a file using Numpy's genfromtxt but specifying only part of the directory path?
问题
我想使用genfromtxt打开位于目录a/b/foldername_12345678中的文件。以下内容适用于我：
file = np.genfromtxt("a/b/foldername_12345678/filename")
但是，我不想追踪目录路径末尾的数字（它们与“foldername”唯一关联）。换句话说，我想在不指定完整目录路径的情况下打开文件。在Linux中，我可以通过以下方式实现：
cat a/b/foldername*/filename
如何在genfromtxt中实现相同的效果？
英文:
I would like to open a file located in the directory a/b/foldername_12345678 using genfromtxt. The following works for me
file = np.genfromtxt("a/b/foldername_12345678/filename")
However, I don't want to keep track of the numbers at the end of the directory path in which the file is located (they are uniquely associated with "foldername"). In other words, I would like to open the file without specifying the full directory path. In linux, I can do this via e.g.
cat a/b/foldername*/filename
How can I do the same with genfromtxt?

你可以在glob库中使用通配符。
import numpy as np
import glob
filepath = glob.glob("a/b/foldername*/filename")[0]
file = np.genfromtxt(filepath)
0索引假设只有一个可能的文件会使用这个通配符被找到。
英文:
You can use wildcards with the glob library.
import numpy as np
import glob
filepath = glob.glob("a/b/foldername*/filename")[0]
file = np.genfromtxt(filepath)
The 0 indexing assumes that there is only one possible file that will be found using this wildcard.
