Lambda rank python
bank_ratios['rank3'] = bank_ratios['Advance to Deposit'].apply(lambda x:0 if x>100% or x<85% else `rank(ascending=False))` I want to rank the company based on the value, but I want to return a value 0 if <80% or >100%, if it is in between, rank the company. In this code it says invalid syntax. Here I used the this column as object.

TīmeklisLambdaRank正是基于这个思想演化而来，其中Lambda指的就是红色箭头，代表下一次迭代优化的方向和强度，也就是梯度。 具体来说，由于需要对现有的loss或loss的梯度进行改进，而NDCG等指标又不可 … TīmeklisA Python lambda function behaves like a normal function in regard to arguments. Therefore, a lambda parameter can be initialized with a default value: the parameter n takes the outer n as a default value. The Python lambda function could have been written as lambda x=n: print(x) and have the same result.

TīmeklisIf all of the numbers in x are unique, this works: x = [4,7,9,10,6,11,3] seq = sorted(x) index = [seq.index(v) for v in x] The technique is to sort the input list, then look up the position of each value from the original list in the sorted one, storing the results in a list via list comprehension.
