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
