python - Pandas :数据文件中没有列名

Question

我正在尝试处理一个数据集以供 DataScience 使用，但它没有列名。 df.head()的输出如下图所示:

   1  73                  Not in universe   0  0.1   0.2  Not in universe.1
0  2  58   Self-employed-not incorporated   4   34     0    Not in universe
1  3  18                  Not in universe   0    0     0        High school
2  4   9                  Not in universe   0    0     0    Not in universe
3  5  10                  Not in universe   0    0     0    Not in universe
4  6  48                          Private  40   10  1200    Not in universe

我想看到的是

0  1  73                  Not in universe   0  0.1   0.2  Not in universe.1
1  2  58   Self-employed-not incorporated   4   34     0    Not in universe
2  3  18                  Not in universe   0    0     0        High school
3  4   9                  Not in universe   0    0     0    Not in universe
4  5  10                  Not in universe   0    0     0    Not in universe
5  6  48                          Private  40   10  1200    Not in universe

我可以随机分配列名，但有更好的方法吗？

加载文件时没有指定它是否有标题行，默认情况下它从第一行推断它，如果缺少则传递 header=None:

df = pd.read_csv(file_path, header=None)
