要返回索引是否单调递增(仅相等或递增)的值,请使用index.is_monotonic_increasing属性。
首先,导入所需的库 -
import pandas as pd
创建索引 -
index = pd.Index([10, 20, 20, 30, 40])
显示索引 -
print("Pandas Index...\n",index)
检查索引是否单调递增 -
print("\nIs the Pandas index monotonic increasing?\n",index.is_monotonic_increasing)
以下是代码 -
import pandas as pd # 创建索引 index = pd.Index([10, 20, 20, 30, 40]) # 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增 print("\nIs the Pandas index monotonic increasing?\n",index.is_monotonic_increasing)输出结果
这将产生以下代码 -
Pandas Index... Int64Index([10, 20, 20, 30, 40], dtype='int64') Array... [10 20 20 30 40] Is the Pandas index monotonic increasing? True
