Python Pandas – 找出两个数据帧之间的差异

2023-06-02 20:24:03 524

要找到两个DataFrame之间的差异，您需要检查其是否相等。另外，检查列的相等性。

让我们用两列创建DataFrame1-

dataFrame1 = pd.DataFrame(
   {
      "Car": ['BMW', 'Lexus', 'Audi', 'Mustang', 'Bentley', 'Jaguar'],
      "Units": [100, 150, 110, 80, 110, 90] }
)

创建具有两列的DataFrame2-

dataFrame2 = pd.DataFrame(
   {
      "Car": ['BMW', 'Lexus', 'Audi', 'Mustang', 'Bentley', 'Jaguar'],
      "Units": [100, 150, 110, 80, 110, 90]
   }
)

检查特定列“单位”的相等性-

dataFrame2['Units'].equals(dataFrame1['Units'])

检查两个数据帧的相等性-

Are both the DataFrames equal?",dataFrame1.equals(dataFrame2)

示例

以下是代码-

import pandas as pd

#CreateDataFrame1
dataFrame1 = pd.DataFrame(
   {
      "Car": ['BMW', 'Lexus', 'Audi', 'Mustang', 'Bentley', 'Jaguar'],
      "Units": [100, 150, 110, 80, 110, 90] }
)

print"DataFrame1 ...\n",dataFrame1

#CreateDataFrame2
dataFrame2 = pd.DataFrame(
   {
      "Car": ['BMW', 'Lexus', 'Audi', 'Mustang', 'Bentley', 'Jaguar'],
      "Units": [100, 150, 110, 80, 110, 90]
   }
)

print"\nDataFrame2 ...\n",dataFrame2


#checkforspecificcolumnUnitsequality
print"\nBoth the DataFrames have similar Units column? ",dataFrame2['Units'].equals(dataFrame1['Units'])

#checkforequality
print"\nAre both the DataFrames equal? ",dataFrame1.equals(dataFrame2)

输出结果

这将产生以下输出-

DataFrame1 ...
       Car   Units
0      BMW     100
1    Lexus     150
2     Audi     110
3  Mustang      80
4  Bentley     110
5   Jaguar      90

DataFrame2 ...
       Car   Units
0      BMW     100
1    Lexus     150
2     Audi     110
3  Mustang      80
4  Bentley     110
5   Jaguar      90

Both the DataFrames have similar Units column? True

Are both the DataFrames equal? True
