shape과 reshape에 대한 이해

import pandas as pd import numpy as np data_set = [[1,2,3], [2,3,4], [3,4,5], [4,5,6]] print(type(data_set)) #출력 column_name = ['No1', 'No2', 'No3'] index_name = ['Index1', 'Index2', 'Index3', 'Index4'] df = pd.DataFrame(data = data_set, columns = column_name, index = index_name) print(df) print(type(df)) #출력 print(df.shape) #출력 (4, 3) data_set_reshape = np.reshape(np.array(data_set), (-1, 6)) # 동일 결과 - data_set_reshape = np.reshape(arr, (2, 6...
