Python Pandas – 查找两个 DataFrame 之间的差异
pythonserver side programmingprogramming更新于 2025/10/27 14:36:17
要查找两个 DataFrame 之间的差异，您需要检查其是否相等。另外，检查列是否相等。
让我们创建具有两列的 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"Units"是否相等−
dataFrame2['Units'].equals(dataFrame1['Units'])
检查两个 DataFrames 是否相等 −
Are both the DataFrames equal?",dataFrame1.equals(dataFrame2)
示例
以下是代码 −
import pandas as pd
# 创建 DataFrame1
dataFrame1 = pd.DataFrame(
{
"Car": ['BMW', 'Lexus', 'Audi', 'Mustang', 'Bentley', 'Jaguar'],
"Units": [100, 150, 110, 80, 110, 90] }
)
print"DataFrame1 ...\n",dataFrame1
# 创建 DataFrame2
dataFrame2 = pd.DataFrame(
{
"Car": ['BMW', 'Lexus', 'Audi', 'Mustang', 'Bentley', 'Jaguar'],
"Units": [100, 150, 110, 80, 110, 90]
}
)
print"\nDataFrame2 ...\n",dataFrame2
# 检查特定列的单位是否相等
print"\nBoth the DataFrames have similar Units column? ",dataFrame2['Units'].equals(dataFrame1['Units'])
# 检查是否相等
print"\nAre both the DataFrames equal? ",dataFrame1.equals(dataFrame2)
输出
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
