熊猫:数据文件中没有列名

Question

我正在尝试处理数据集以使用DataScience,但它没有列名.输出df.head()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

我可以指定随机列名,但是有更好的方法吗？

您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,如果它缺少则传递header=None:

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