对于每行，用line[1:-1]修剪第一个和最后一个字符，用.split()分隔空白，并用float()解析每个浮点数.

For each line, trim off the first and last char with line[1:-1], split by whitespace with .split(), and parse each float with float().

line = "[ 0.          0.         -0.24604772  0.        ]"
floats = [float(item) for item in line[1:-1].split()]

print(floats)
>>> [0.0, 0.0, -0.24604772, 0.0]
