我也不知道这些代码当初是拿来干什么的,似乎是随手写的一些numpy数组操作脚本
2024-02-10,重新跑了一遍,把jupyter notebook的结果放在上面(相比于原始代码略有修改):
原始代码:
import numpy as np
import utils as ut
import random
from copy import deepcopy
# a=np.array([[1,2,3,4],
# [5,6,7,8]])
#
# for i in range(0,a.shape[1]):
# print(a[:,i])
# a=np.array([[1,2,3],
# [2,4,5],
# [5,6,7]])
# b=np.array([15,5,5])
# b1=b.reshape(1,-1)
# c=np.concatenate((b1,a),axis=0)
# print('done')
#
# a=np.array([[1,2,3],
# [2,4,5],
# [5,6,7]])
#
# for col in range(1, a.shape[1]):
# print()
# def highest_freq(lst):
# counter={}
# for item in lst:
# if item in counter.keys():
# counter[item]+=1
# else:
# counter[item]=1
#
# maxC=-1
# mostElement=None
# for key in counter.keys():
# if counter[key]>maxC:
# mostElement=key
# maxC=counter[key]
# return mostElement
#
# lst = [1,1,1,1,2,2,2]
# print(highest_freq(lst))
# print(lst[:5])
# a=np.empty((3,10))
# b=np.array([[1,2],[4,5],[5,6]])
# start_index=0
# a[:,start_index:start_index+b.shape[1]]=b
# print('done')
#
# y=np.array([
# [1,2,3.1],
# [3,4,100],
# ['喊',3,5]
# ])
#
#
# print(np.issubdtype(y.dtype, np.integer))
def highest_freq_helper(reverse_counter,item):
for key in reverse_counter.keys():
for value in reverse_counter[key]:
if value == item:
reverse_counter[key].remove(item)
if (key + 1) in reverse_counter.keys():
reverse_counter[key + 1].append(item)
else:
reverse_counter[key + 1] = [item]
return deepcopy(reverse_counter)
def highest_freq(lst):
reverse_counter = {0:list(set(lst))}
# 遍历每一个list元素
for item in lst:
reverse_counter=highest_freq_helper(reverse_counter,item)
# print('debug here')
# print(reverse_counter)
max_count=-1
for key in reverse_counter.keys():
if key>max_count:
max_count=key
# print(max_count)
print(random.choice(reverse_counter[max_count]))
highest_freq([1,2,3,4,5,5,4,1])
