python代码如下

def square_sum(numbers):
    print("求和 ")
    sum = 0
    for num in numbers:
        sum +=num ** 2
    return sum
print(square_sum([1,2,3,4]))

import  xlrd
data=xlrd.open_workbook("./1.xls")
data.sheet_names()
print(data.sheet_names())

输出结果为乱码

excelfile.py
��������ƽ����

['Sheet1']

配置vscode解决乱码问题，点击扩展应用-Code Runner -点击设置齿轮按钮-exec-编辑settings.json -将python行修改为 “python”: “set PYTHONIOENCODING=UTF8 && python -u”,
