我有一个文本文件形式的以下数据，我想加载到python：
pclass survived name
0 1 1 Allen, Miss. Elisabeth Walton
1 1 1 Allison, Master. Hudson Trevor
2 1 0 Allison, Miss. Helen Loraine
3 1 0 Allison, Mr. Hudson Joshua Creighton
4 1 0 Allison, Mrs. Hudson J C (Bessie Waldo Daniels)
5 1 1 Anderson, Mr. Harry
6 1 1 Andrews, Miss. Kornelia Theodosia
7 1 0 Andrews, Mr. Thomas Jr
8 1 1 Appleton, Mrs. Edward Dale (Charlotte Lamson)
9 1 0 Artagaveytia, Mr. Ramon
10 1 0 Astor, Col. John Jacob
由于空格不是常量，并且由于最后一个字段（名称）之间有空格，因此我无法解析它。我尝试了以下方法：
pd.read_csv("test.csv",sep = "\s+", header=0, index_col=0)
但是它给出了一个错误：
CParserError: Error tokenizing data. C error: Expected 7 fields in line 5, saw 8
答案 0 :(得分：3)
'\s+'假设一个或多个空格仍在解析您的最终列。而是使用假定两个或更多的正则表达式。
pd.read_csv("test.csv", sep="\s{2,}", header=0, index_col=0, engine='python')

您可以使用pandas.read_fwf（又名：固定宽度格式）来执行此操作：
<强>代码：
df = pd.read_fwf(StringIO(data), header=1, index_col=0)
测试代码：
from io import StringIO
import pandas as pd
data = u"""
pclass survived name
0 1 1 Allen, Miss. Elisabeth Walton
1 1 1 Allison, Master. Hudson Trevor
2 1 0 Allison, Miss. Helen Loraine
3 1 0 Allison, Mr. Hudson Joshua Creighton
4 1 0 Allison, Mrs. Hudson J C (Bessie Waldo Daniels)
5 1 1 Anderson, Mr. Harry
6 1 1 Andrews, Miss. Kornelia Theodosia
7 1 0 Andrews, Mr. Thomas Jr
8 1 1 Appleton, Mrs. Edward Dale (Charlotte Lamson)
9 1 0 Artagaveytia, Mr. Ramon
10 1 0 Astor, Col. John Jacob"""
df = pd.read_fwf(StringIO(data), header=1, index_col=0)
print(df)
<强>结果：

2 1 0 Allison, Miss. Helen Loraine
