How do I convert a .tsv to .csv?

Question

Trying to convert a .tsv to a .csv. This:

import csv

# read tab-delimited file
with open(\'DataS1_interactome.tsv\',\'rb\') as fin:
    cr = csv.reader(fin         


        

Answer 1

While attempting to write to the CSV file, it encounters a token where it has to insert an escape character. However, you have not defined one.

Dialect.escapechar

A one-character string used by the writer to escape the delimiter if quoting is set to QUOTE_NONE and the quotechar if doublequote is False. On reading, the escapechar removes any special meaning from the following character. It defaults to None, which disables escaping.

Source: https://docs.python.org/2/library/csv.html#csv.Dialect.escapechar

Example code:

# write comma-delimited file (comma is the default delimiter)
with open('interactome.csv','wb') as fou:
    cw = csv.writer(fou, quotechar='', quoting=csv.QUOTE_NONE, escapechar='\\')
    cw.writerows(filecontents)
