Python Pandas – 检查两个 DataFrame 的任何特定列是否相等
要检查两个DataFrame的任何特定列是否相等，请使用该equals()方法。让我们首先创建具有两列的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', 'Mercedes', 'Jaguar'],
"Units": [100, 150, 110, 80, 110, 90]
}
)检查特定列Units的相等性-
dataFrame2['Units'].equals(dataFrame1['Units'])
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
#检查是否相等
print"\nAre both the DataFrame objects equal? ",dataFrame1.equals(dataFrame2)
#检查特定列的单位相等
print"\nAre both the DataFrames have similar Units column? ",dataFrame2['Units'].equals(dataFrame1['Units']
)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
Are both the DataFrame objects equal? True
Are both the DataFrames have similar Units column? True热门推荐
