python - How to sort a list of lists based on length of inner list?

Question

I want to sort a list of lists based on the length of the second item in the sublists, like this:

Input:

list = [['A', '1234', 'X'],['B', '12', 'X'],['C', '12345', 'X'],['D', '123', 'X']]

Output:

list = [['C', '12345', 'X'],['A', '1234', 'X'],['D', '123', 'X'],['B', '12', 'X']]

What i have so far is:

list = sorted(list, key=len, reverse=True)

But I'm not sure how to get it to look at length of on specific item in the lists. Thanks in advance!

Answer 1

Using sort or sorted with custom key.

Ex:

data = [['A', '1234', 'X'],['B', '12', 'X'],['C', '12345', 'X'],['D', '123', 'X']]
data.sort(key=lambda x: len(x[1]), reverse=True)

or sorted

data = sorted(data, key=lambda x: len(x[1]), reverse=True)

---

print(data)
