Question

进行此练习以学习熊猫。我认为根据错误提供的数据库存在问题。

想法？

代码：

import numpy as np
import scipy as sp
import pandas as pd
import matplotlib as mpl

url = 'https://raw.githubusercontent.com/justmarkham/DAT8/master/data/chipotle.tsv'
chipo = pd.read_csv(url, delimiter='/t')
print(chipo.head(10))

输出：

ex22_chipotle.py:7: ParserWarning: Falling back to the 'python' engine because the 'c' engine does not support regex separators (separators > 1 char and different from '\s+' are interpreted as regex); you can avoid this warning by specifying engine='python'.
  chipo = pd.read_csv(url, delimiter='/t')

使用\t将tab用作分隔符：

chipo = pd.read_csv(url, delimiter='\t')

print(chipo.head(10))
