一.测试数据
二.代码实现
1 # -*- coding: utf-8 -*- 2 """ 3 Created on Sun Jul 7 11:35:01 2019 4 加载数据时对指定列进行转换 5 @author: zhen 6 """ 7 8 import numpy as np 9 np.set_printoptions(suppress=True) # 禁止numpy按科学计数法展示数据 10 11 def color2num(str): 12 dict = {"居民用电":220, "工业用电":380, "高压":11000, "超高压":500000, "特高压":1000000} 13 return dict[str] 14 15 data = np.loadtxt("data.csv", delimiter=",", converters={1:color2num}, encoding="gbk") 16 print(data)
三.结果
