Given a non-empty list of strings of the same length, how do I create a list of lists of the letters at each position in the string without using zip? [closed] solved Given a non-empty list of strings of the same length, how do I create a list of lists of the letters at each … Read more
Well, for this example, you could use list comprehension with slicing. a = [[1, 2], [1, 2, 3], [1, 2, 3, 4]] b = [x[1:] for x in a] 0 solved Remove the first items in a list of lists – make a copy instead of modifying in-place
Here is a simple, but not most efficient way. you can achieve that by two step: convert list to set, to remove the duplicate number. use heap to find nlargest and nsmallest in set def difference(list1): set1 = set(list1) return heapq.nlargest(2, set1)[1] – heapq.nsmallest(2, set1)[1] Here is a one pass way, more efficient way, use … Read more
I think the problem is the assignment equation = eqn. Since eqn is a list, it is a mutable and thus passed as a reference, when you assign a mutable, the variable actually contains a pointer to that object. This means that equation and eqn are the same list. You should from copy import deepcopy … Read more
