用pandas读取excel文件显示FileNotFoundError

Question

#读取excel文件
import pandas as pd
import numpy as np
a=pd.read_excel("boston_housing_data.xlsx",usecols=range(0,10)) 
b=a.values  #提取其中的数据
c=a.describe()  #对数据进行统计描述
print(b)

运行结果

boston_housing_data.xlsx 这个文件的位置要写清楚。
比如说，这个文件在 D盘，就写成a=pd.read_excel(r"D:\boston_housing_data.xlsx",usecols=range(0,10))
