Python Pandas - 返回索引是否为单调递减(仅相等或递减)值
如要返回索引是否为单调递减(仅相等或递减)的值,请使用 index.is_monotonic_decreasing 属性。
首先,导入所需的库 −
import pandas as pd
创建索引 −
index = pd.Index([50, 40, 30, 30, 30])
显示索引 −
print("Pandas Index...\n",index)
检查索引是否单调递减 −
print("\nIs the Pandas index monotonic decreasing?\n",index.is_monotonic_decreasing)
示例
代码如下 −
import pandas as pd # Creating the index index = pd.Index([50, 40, 30, 30, 30]) # Display the index print("Pandas Index...\n",index) # Return an array representing the data in the Index print("\nArray...\n",index.values) # Check if the index monotonic decreasing print("\nIs the Pandas index monotonic decreasing?\n",index.is_monotonic_decreasing)
输出
这将生成以下代码 −
Pandas Index... Int64Index([50, 40, 30, 30, 30], dtype='int64') Array... [50 40 30 30 30] Is the Pandas index monotonic decreasing? True
