The read_csv() function of pandas can be used to read a gzipped TSV file. You need to pass compression='gzip' as an argument to this function.
Here is an example of reading a gzipped TSV file with a header:
import pandas as pd
df = pd.read_csv("your_file.gz", sep="\t", header=0, compression="gzip")
The content of the file will be in the dataframe 'df'.
