My code: from elasticsearch import Elasticsearch import csv es = Elasticsearch(["9200"]) # Replace the following Query with your own Elastic Search Query res = es

问题 I have a method like the following: def slice_list(my_list, slice_point): my_list = my_list[:slice_point] print("Inside method: ", my_list) return I have a test for it like the following: if __name__ == "__main__": my_list = [1,2,3,4,5] slice_point = 3 slice_list(my_list, slice_point) print("Outside method: ", my_list) The output I get is not what I expected for, in the sense that the list is not ultimately edited >>>Inside method: [1, 2, 3] >>>Outside method: [1, 2, 3, 4, 5] But when I do an

问题 I'm working with a big dictionary and for some reason I also need to work on small random samples from that dictionary. How can I get this small sample (for example of length 2)? Here is a toy-model: dy={'a':1, 'b':2, 'c':3, 'd':4, 'e':5} I need to perform some task on dy which involves all the entries. Let us say, to simplify, I need to sum together all the values: s=0 for key in dy.key: s=s+dy[key] Now, I also need to perform the same task on a random sample of dy; for that I need a random

问题 I have just installed tabulate for python in order to tabulate my output in the terminal. When ever i try to import tabulate into python 3.4, it gives me an error saying ImportError: No module named 'tabulate' But, whenever I import it into a python2.7 console it seems to work.
