Difficulty importing .dat file
提问by zsljulius
I am somehow having difficulty reading in this file into python with pandas read_table function. http://www.ssc.wisc.edu/~bhansen/econometrics/invest.dat
我以某种方式在使用 pandas read_table 函数将此文件读入 python 时遇到了困难。 http://www.ssc.wisc.edu/~bhansen/econometrics/invest.dat
This is my code:
这是我的代码：
pd.read_table(f,skiprows=[0], sep="")
Which yields error:
这会产生错误：
TypeError: ord() expected a character, but string of length 0 found

Dont know about read_table, but you can read this file directly as follows:
不知道read_table，但是你可以直接读取这个文件如下：
import pandas as pd
with open('/tmp/invest.dat','r') as f:
next(f) # skip first row
df = pd.DataFrame(l.rstrip().split() for l in f)
print(df)
Prints:
印刷：
0 1 2 3
0 17.749000 0.66007000 0.15122000 0.33150000
1 3.9480000 0.52889000 0.11523000 0.56233000
2 14.810000 3.7480300 0.57099000 0.12111000

The same can be obtained as follows:
同样可以如下获得：
df = pd.read_csv('/tmp/invest.dat', sep='\s+', header=None, skiprows=1)
