[python] How to load a tsv file into a Pandas DataFrame?

I'm new to python and pandas. I'm trying to get a tsv file loaded into a pandas DataFrame.

This is what I'm trying and the error I'm getting:

>>> df1 = DataFrame(csv.reader(open('c:/~/trainSetRel3.txt'), delimiter='\t'))

Traceback (most recent call last):
  File "<pyshell#28>", line 1, in <module>
    df1 = DataFrame(csv.reader(open('c:/~/trainSetRel3.txt'), delimiter='\t'))
  File "C:\Python27\lib\site-packages\pandas\core\frame.py", line 318, in __init__
    raise PandasError('DataFrame constructor not properly called!')
PandasError: DataFrame constructor not properly called!

The answer is


Try this:

import pandas as pd
DataFrame = pd.read_csv("dataset.tsv", sep="\t")

As of 17.0 from_csv is discouraged.

Use pd.read_csv(fpath, sep='\t') or pd.read_table(fpath).


Use read_table(filepath). The default separator is tab


Try this

df = pd.read_csv("rating-data.tsv",sep='\t')
df.head()

enter image description here

You actually need to fix the sep parameter.


df = pd.read_csv('filename.csv', sep='\t', header=0)

You can load the tsv file directly into pandas data frame by specifying delimitor and header.


open file, save as .csv and then apply

df = pd.read_csv('apps.csv', sep='\t')

for any other format also, just change the sep tag


data = pd.read_csv('your_dataset.tsv', delimiter = '\t', quoting = 3)

You can use a delimiter to separate data, quoting = 3 helps to clear quotes in datasst
