Question

'''
明明导入xlutils库，为什么还提示copy未定义
Traceback (most recent call last):
File "D:/python学习/Chapter-3-17-if语句进行xls数据处理.py", line 9, in <module>

nwb = copy(read_book)

NameError: name 'copy' is not defined
先导入库，读取工作簿，读取工作表，读取对应的列，做逻辑，导入
'''
import xlrd
import xlutils

read_book = xlrd.open_workbook('工资表.xls')
read_sheet = read_book.sheet_by_name('工作表')
nwb = copy(read_book)
nws = nwb.get_sheet('工作表')
read_lie = read_sheet.col_values(1)
hang_num = 0
for n in read_lie:

if type(n) == float:
    if n > 180:
        nws.write(hang_num, 2, '真有钱！')
    elif n > 150:
        nws.write(hang_num, 2, '有点前嘛！')
    elif n > 100:
        nws.write(hang_num, 2, '普通打工族！')
    elif n > 80:
        nws.write(hang_num, 2, '生活苦难！')
    else:
        nws.write(hang_num, 2, '加油啊！')
hang_num += 1

nwb.save('Chapter-3-17形成的表格.xls')

如果你要直接调用copy方法的话导入需要这么写
from xlutils.copy import copy
