How do you find the largest list in a list Python?

Explanation

1. Create list of tuple with index as first element and len(l) (length of list) as second element:
2. Sort above list by second element in tuple that tuple with longest length gets to the end of the list:
3. Catch the last tuple and its first element:
4. Use above result as the index in ll to get the longest list:

How do you find the length of a list?

What is the maximum possible length of an identifier?

the new limit is 31 characters—although identifiers may be longer, they must differ in the first 31 characters if you want to be sure that your programs are portable.

What is the maximum possible length of a string in Python?

With a 64-bit Python installation, and 64 GB of memory, a Python 2 string of around 63 GB should be quite feasible. If you can upgrade your memory much beyond that, your maximum feasible strings should get proportionally longer. But this comes with a hit to the runtimes.

How do you find the maximum length of a list?

Use max() to find the longest string in a list. Call max(a_list, key=len) to return the longest string in a_list by comparing the lengths of all strings in a_list .

How do you find the max of a list?

3. The sum of inner list elements.
4. The maximum of inner list elements.

How do you total a list in Python?

See the code below:

1. def sum_of_list(l): total = 0. for val in l: total = total + val. return total. ​ my_list = [1,3,5,2,4]
2. def sum_of_list(l,n): if n == 0: return l[n]; return l[n] + sum_of_list(l,n-1) ​ my_list = [1,3,5,2,4]
3. my_list = [1,3,5,2,4] print “The sum of my_list is”, sum(my_list) Run.
