Python Pandas - 获取请求标签的整数位置
要获取 Pandas 中请求标签的整数位置,请使用 **index.get_loc()** 方法。首先,导入所需的库 -
import pandas as pd
创建 Pandas 索引对象 -
index = pd.Index(list('pqrstuvwxyz'))
显示 Pandas 索引 -
print("Pandas Index...\n",index)
从给定的索引获取整数位置 -
print("\nDisplay integer location from given index...\n",index.get_loc('w')) print("\nDisplay integer location from given index...\n",index.get_loc('z'))
示例
以下是代码 -
import pandas as pd # create Pandas index object index = pd.Index(list('pqrstuvwxyz')) # Display the Pandas index print("Pandas Index...\n",index) # Return the number of elements in the Index print("\nNumber of elements in the index...\n",index.size) # get integer location from the given index print("\nDisplay integer location from given index...\n",index.get_loc('w')) print("\nDisplay integer location from given index...\n",index.get_loc('z'))
输出
这将产生以下输出 -
Pandas Index... Index(['p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'], dtype='object') Number of elements in the index... 11 Display integer location from given index... 7 Display integer location from given index... 10
