如何用一条线连接非nan值？

data = [1, 2, float('nan'), 3, float('nan'), 4]
result = []
for value in data:
    if not math.isnan(value):
        result.append(value)
result_str = ' '.join(str(value) for value in result)
print(result_str)

double[] data = {1, 2, Double.NaN, 3, Double.NaN, 4};
StringBuilder result = new StringBuilder();
for (double value : data) {
    if (!Double.isNaN(value)) {
        result.append(value).append(" ");
    }
}
String resultStr = result.toString().trim();
System.out.println(resultStr);
