List of lists: how to delete all lists that contain certain values?-CodePudding

There's a list of listss (or it could be tuple of tuples). For example:

my_list = [
  ['A', 7462],
  ['B', 8361],
  ['C', 3713],
]

What would be the most efficient way to filter out all lists that have a value 'B' in them, considering that the number (or other values) might change?

The only way I came up with so far is using loops but it's very inefficient in this case, so I'd like to know if it's possible to avoid loops in this case.

CodePudding user response：

You can create a new list, filtering out the stuff you don't want. In python this is usually done with a list comprehension:

new_list = [sublist for sublist in my_list if sublist[0] != 'B']
