How to save a DataFrame in a tabulation delimited file (.tsv) in Python?

In Python, to create a tabulation delimited file from a dataframe, the best option is to use the .to_csv() method while specifying the delimiter character:

myDataframe.to_csv('filename.tsv', sep = '\t')

To prevent the index of each row from being stored in the file, add index=False as a second parameter:

myDataframe.to_csv('filename.tsv', sep = '\t', index=False)
