How to load a tsv file into a Pandas DataFrame?


Question

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!

Accepted Answer

Note: As of 17.0 from_csv is discouraged: use pd.read_csv instead

The documentation lists a .from_csv function that appears to do what you want:

DataFrame.from_csv('c:/~/trainSetRel3.txt', sep='\t')

If you have a header, you can pass header=0.

DataFrame.from_csv('c:/~/trainSetRel3.txt', sep='\t', header=0)

As of 17.0 from_csv is discouraged.

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