二、将字典内容写入 excel文件
1
假设已有字典内容为：
即student列表里有4个字典，
第一个字典里面有3对key-value
"num": 1,
"name": "cod1",
"wfm": 0.1
student = [{"num": 1, "name": "cod1", "wfm": 0.1},{"num": 2, "name": "cod2", "wfm": 0.2},{"num": 3, "name": "cod3", "wfm": 0.3},{"num": 4, "name": "cod4", "wfm": 0.4},
]2 导入Workbook并实力化
from openpyxl import Workbook
workbook = Workbook()3 激活sheet-设置sheet名-插入标题-
# 默认sheet
sheet = workbook.active # 激活sheet
sheet.title = "openpyxl" # 设置sheet名字
sheet.append(["num", "name", "wfm"]) # 插入标题
for data in student: # 列表循环读取dictsheet.append(list(data.values()))
workbook.save("openpyxl.xlsx")二、将字典内容写入 excel文件（完整代码）
student = [{"num": 1, "name": "cod1", "wfm": 0.1},{"num": 2, "name": "cod2", "wfm": 0.2},{"num": 3, "name": "cod3", "wfm": 0.3},{"num": 4, "name": "cod4", "wfm": 0.4},
]
import pdb
pdb.set_trace()from openpyxl import Workbook
workbook = Workbook()# 默认sheet
sheet = workbook.active # 激活sheet
sheet.title = "openpyxl" # 设置sheet名字
sheet.append(["num", "name", "wfm"]) # 插入标题
for data in student: # 列表循环读取dictsheet.append(list(data.values()))
workbook.save("openpyxl.xlsx")
