怎样将excel中的数据自动填入一个字符串并顺序输出？

我想将excel中的数据自动填入一个字符串并顺序输出

问题相关代码

from docxtpl import DocxTemplate
from openpyxl import load_workbook
import os

def replace(obj):
    if obj is None:
        obj = ''
        return obj

wb = load_workbook("excel.xlsx")

'''
这是excel.xlsx中的内容
AID            BID              CID
123            2022-07      e:147
456            2022-09      g:258
'''

ws = wb['Sheet1']
contexts = []
for row in range(2, ws.max_row + 1):
    a_id = ws["A" + str(row)].value
    b_id = ws["B" + str(row)].value
    c_id = ws["C" + str(row)].value
    context="BId \"{{b_id}}\" -CId \"{{c_id}}\" -APath \"D:\\{{a_id}}.txt\""
    contexts.append(context)
contexts

for context in contexts:
    print(context)

运行结果及报错内容
BId "{{B_id}}" -CId "{{c_id}}" -APath "D:{{a_id}}.txt"
BId "{{B_id}}" -CId "{{c_id}}" -APath "D:{{a_id}}.txt"

我想要达到的结果
输出以下结果
BId "2022-07" -CId "e:147" -APath "D:\123.txt"
BId "2022-09" -CId "g:258" -APath "D:\456.txt"

context="BId \"{{b_id}}\" -CId \"{{c_id}}\" -APath \"D:\\{{a_id}}.txt\""

改成

context=f"BId \"{{b_id}}\" -CId \"{{c_id}}\" -APath \"D:\\{{a_id}}.txt\""
