Hello everyone. during my internship I have to handle tsv files. I would absently do it with a python script to perform my skill.

As you can see my third column are numbers. but what I want is just to keep genotype O/1 and 1/0 and not 0/0 in this column. However I dont know which method I can use into my third column to find this type of genotype.

Thank you in advance for your assistance with this.

  import pandas as pd 
  mon_data = pd.read_table('2zaza.del.tsv', header=None)

  genotype = mon_data.loc[:,3]

    genotype
    0        0/0:-0,-9.03,-180
    1         0/0:-0,-3.61,-72
    2        0/0:-0,-7.22,-144
    3        0/0:-0,-7.22,-144
    4       0/0:-0,-11.44,-228
    5        0/0:-0,-6.62,-132
