Python Pandas - 如果索引单调递减（仅相等或递减）值则返回
要返回索引是否单调递减（仅相等或递减）值，请使用index.is_monotonic_decresing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)检查指数是否单调递减-
print("\nIs the Pandas index monotonic decreasing?\n",index.is_monotonic_decreasing)示例
以下是代码-
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)
#返回一个表示索引中数据的数组
print("\nArray...\n",index.values)
#检查索引是否单调递减
print("\nIs the Pandas index monotonic decreasing?\n",index.is_monotonic_decreasing)输出结果这将产生以下代码-
Pandas Index... Int64Index([50, 40, 30, 30, 30], dtype='int64') Array... [50 40 30 30 30] Is the Pandas index monotonic decreasing? True
