每日10行代码159：批量修改多个excel文件的列名

背景：接上一章，进一步增强功能，实现批量处理的功能。

import openpyxl
import os 

# 定义一个字典
my_dict = {'dth1':'代替换1'
			,'dth2':'代替换2'
			,'dth3':'代替换3'
}


def change_column_name(path,my_dict):	
	wb = openpyxl.load_workbook(path)
	ws = wb.active

	for c in ws[1]:
		if c.value.strip() in my_dict:
			c.value=my_dict[c.value.strip()]

	wb.save(path)


base_dir = r'E:\data1'
for fn in os.listdir(base_dir):
    path=os.path.join(base_dir,fn)
    print(path)
    change_column_name(path,my_dict)
