How do you access specific elements from the nested lists

2024/9/22 6:43:58

I am trying to access elements from the nested lists. For example,

file = [[“Name”,”Age”,”Medal”,”Location”],[“Jack”,”31”,”Gold”,”China”],[“Jim”,”29”,”Silver”,”US”]]

This data contains at least 3000 lists. I only want to put the data into a new list with the column Name and “Location”

Output should be: [[“Name”,”Location”],[“Jack”,”China”],[“Jim”,”US”]]

This looks like a data frame. But I cannot use any module to separate the columns. How can I code it using python built-in function and methods. I tried for loops but failed,

Answer

This is a list comprehension problem:

newfile = [row[0:2] for row in file]
