将数据透视表创建为 DataFrame – Python Pandas
要创建数据透视表，请使用将电子表格样式的数据透视表创建为DataFrame。pandas.pivot_table()
首先，导入所需的库-
import pandas as pd
使用团队记录创建一个DataFrame-
dataFrame = pd.DataFrame({'Team ID': {0: 5, 1: 9, 2: 6, 3: 11, 4: 2, 5: 7 },'Team Name': {0: 'India', 1: 'Australia', 2: 'Bangladesh', 3: 'South Africa', 4: 'Sri Lanka', 5: 'England'},'Team Points': {0: 95, 1: 93, 2: 42, 3: 60, 4: 80, 5: 55},'Team Rank': {0: 'One', 1: 'Two', 2: 'Six', 3: 'Four', 4: 'Three', 5: 'Five'}})创建一个数据透视表：只有一列-
pd.pivot_table(dataFrame, index = ["Team ID"])
示例
以下是代码-
import pandas as pd
#createDataFramewithTeamrecords
dataFrame = pd.DataFrame({'Team ID': {0: 5, 1: 9, 2: 6, 3: 11, 4: 2, 5: 7 },'Team Name': {0: 'India', 1: 'Australia', 2: 'Bangladesh', 3: 'South Africa', 4: 'Sri Lanka', 5: 'England'},'Team Points': {0: 95, 1: 93, 2: 42, 3: 60, 4: 80, 5: 55},'Team Rank': {0: 'One', 1: 'Two', 2: 'Six', 3: 'Four', 4: 'Three', 5: 'Five'}})
print"DataFrame...\n",dataFrame
print"\n... Pivot ..."
print(pd.pivot_table(dataFrame, index = ["Team ID"]))输出结果这将产生以下输出-
DataFrame...
