python - Having trouble reading files with "one value" using numpy loadtxt

Question

I'm trying to read my data files with numpy loadtxt. The data files are just a single column as follows:

1
1
1
2
...

After I load my files, I append them into a single list as follows:

import numpy as np
file_list=[file1, file2, file3, file4]
list_0=[]
for file in file_list:
    tmp = np.loadtxt(file)
    for data in tmp:
        list_0.append(data)

The situation I have trouble with is when the "file" contains only one number. In that case, "tmp" in the code reads like a float and gives me an error message at the loop: "iteration over a 0-d array".

Is there any way to keep "tmp" as an array even with a single value?
