Python_Openpyxl
1. 安装
pip install openpyxl

2. 打开文件
① 创建
from openpyxl import Workbook # 实例化 wb = Workbook() # 激活 worksheet ws = wb.active

3. 储存数据
# 方式一:数据可以直接分配到单元格中(可以输入公式) ws['A1'] = 42 # 方式二:可以附加行,从第一列开始附加(从最下方空白处,最左开始)(可以输入多行) ws.append([1, 2, 3]) # 方式三:Python 类型会被自动转换 ws['A3'] = datetime.datetime.now().strftime("%Y-%m-%d")

4. 创建表(sheet)
# 方式一:插入到最后(default) >>> ws1 = wb.create_sheet("Mysheet") # 方式二:插入到最开始的位置 >>> ws2 = wb.create_sheet("Mysheet", 0)

5. 选择表(sheet)
# sheet 名称可以作为 key 进行索引 >>> ws3 = wb["New Title"] >>> ws4 = wb.get_sheet_by_name("New Title") >>> ws is ws3 is ws4 True

6. 查看表名(sheet)
# 显示所有表名 >>> print(wb.sheetnames) ['Sheet2', 'New Title', 'Sheet1'] # 遍历所有表 >>> for sheet in wb: ... print(sheet.title)

7. 访问单元格(call)
① 单一单元格访问
# 方法一 >>> c = ws['A4'] # 方法二:row 行;column 列 >>> d = ws.cell(row=4, column=2, value=10) # 方法三:只要访问就创建 >>> for i in range(1,101): ... for j in range(1,101): ... ws.cell(row=i, column=j)

② 多单元格访问
# 通过切片 >>> cell_range = ws['A1':'C2'] # 通过行(列) >>> colC = ws['C'] >>> col_range = ws['C:D'] >>> row10 = ws[10] >>> row_range = ws[5:10] # 通过指定范围(行 → 行) >>> for row in ws.iter_rows(min_row=1, max_col=3, max_row=2): ... for cell in row: ... print(cell) <Cell Sheet1.A1> <Cell Sheet1.B1> <Cell Sheet1.C1> <Cell Sheet1.A2> <Cell Sheet1.B2> <Cell Sheet1.C2> # 通过指定范围(列 → 列) >>> for row in ws.iter_rows(min_row=1, max_col=3, max_row=2): ... for cell in row: ... print(cell) <Cell Sheet1.A1> <Cell Sheet1.B1> <Cell Sheet1.C1> <Cell Sheet1.A2> <Cell Sheet1.B2> <Cell Sheet1.C2> # 遍历所有 方法一 >>> ws = wb.active >>> ws['C9'] = 'hello world' >>> tuple(ws.rows) ((<Cell Sheet.A1>, <Cell Sheet.B1>, <Cell Sheet.C1>), (<Cell Sheet.A2>, <Cell Sheet.B2>, <Cell Sheet.C2>), ... (<Cell Sheet.A8>, <Cell Sheet.B8>, <Cell Sheet.C8>), (<Cell Sheet.A9>, <Cell Sheet.B9>, <Cell Sheet.C9>)) # 遍历所有 方法二 >>> tuple(ws.columns) ((<Cell Sheet.A1>, <Cell Sheet.A2>, <Cell Sheet.A3>, ... <Cell Sheet.B7>, <Cell Sheet.B8>, <Cell Sheet.B9>), (
