用$$导入CSV在大熊猫作为分隔符

Question

我试图导入大熊猫以CSV $$作为分隔符，我希望下面的命令来工作：

pd.read_csv('data.csv', delimiter="$$") 

然而，这将返回以下错误：

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), but this causes 'error_bad_lines' to be ignored as it is not supported by the 'python' engine.

是本公司经营甚至有可能在熊猫吗？

Answer 1

您可以逃脱$通过\：

df = pd.read_csv('data.csv', sep="\$\$", engine='python') 

样品：

import pandas as pd 
from pandas.compat import StringIO 

temp=u"""a$$b 
a$$1 
s$$2 
f$$3""" 
#after testing replace 'StringIO(temp)' to 'filename.csv' 
df = pd.read_csv(StringIO(temp), sep="\$\$", engine='python') 
print (df) 
    a b 
0 a 1 
1 s 2 
2 f 3
