Code Sample, a copy-pastable example if possible

Input file: (content of example file)

a1  b1  c1  d1
"   c   y   z
a3  b3  c3  d3
"   d4  s4  d4

Code:

extb = pd.read_csv('example', encoding='utf8', sep='\t', header=None); extb[:]

Output:

0   1   2   3
0   a1  b1  c1  d1
1   \tc\ty\tz\na3\tb3\tc3\td3\n d4  s4  d4

Expected Output

a1  b1  c1  d1
"   c   y   z
a3  b3  c3  d3
"   d4  s4  d4

Question: Can i control input file that have character " ?

As described in docstring, double quote is to handle quoted item by default. - http://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_csv.html

You can do:

import csv
pd.read_csv('example', encoding='utf8', sep='\t', header=None, quoting=csv.QUOTE_NONE)
