一、numpy 二、pandas 2.3 series结构 基本操作 import pandas as pd fandango = pd.read_csv('E:\\唐宇迪机器学习\Python库代码（4个）\\2-数据分析处理库pandas\\fandango_score_comparison.csv') series_film = fandango['FILM'] print(type(series_film)) print(series_film[0:5]) serie_rt = fandango[

一、numpy import numpy data01=numpy.array([1,2,3,4]) data02=numpy.array([[1,2,3,4],[6,9,6,6],[7,9,6,3]]) print(data01) print(data02) print(type(data01)) print(type(data02)) print(data01.shape) print(data02.shape)#二行三列 输出： [1 2 3 4] [[1 2 3 4] [6 9 6 6]
