读取txt文件时如何在熊猫中左对齐

Question

我有一个 info.txt 文件，它看起来像这样：

B 19960331 00100000 00000000000000 00000000000000 00000000000000 00000000 00000000000000 00000000000000 00000000000000
B 19960430 00099100 00000000000000 00000000000000 00000000000000 00000000 00000000000000 00000000000000 00000000000000
B 19960531 00098500 00000000000000 00000000000000 00000000000000 00000000 00000000000000 00000000000000 00000000000000

而当我使用 pandas 阅读时：

import pandas as pd
import numpy as np
df =pd.read_csv('C:\Users\Petter\Desktop\info.txt')
df

输出是：

    B 19960331 00100000 00000000000000 00000000000000 00000000000000 00000000 00000000000000 00000000000000 00000000000000
                                                                     0  B 19960430 00099100 00000000000000 00000000000...
                                                                     1  B 19960531 00098500 00000000000000 00000000000...

这些行离列名很远，无论如何我可以让它们像这样：

    B 19960331 00100000 00000000000000 00000000000000 00000000000000 00000000 00000000000000 00000000000000 00000000000000
0   B 19960430 00099100 00000000000000 00000000000...
1   B 19960531 00098500 00000000000000 00000000000...

我试过了：

df.shift(periods=1, axis="columns")

但现在可以工作

您可以尝试使用pd.read_csv读取文件：

df = pd.read_csv("your_file.txt", sep=r"\s", header=None, dtype=str, engine="python")
print(df)

打印：

   0         1         2               3               4               5         6               7               8               9
