et-xmlfile是一个Python库,用于读取和写入大型Excel文件(xlsx格式)而不消耗大量内存。以下是使用et-xmlfile的一些基本示例:
1. 安装et-xmlfile
```
pip install et-xmlfile
```
2. 读取Excel文件
```python
from openpyxl import load_workbook
from openpyxl.utils import get_column_letter
from et_xmlfile import parse_xml
# 打开Excel文件
workbook = load_workbook(filename='example.xlsx')
# 获取第一个工作表
worksheet = workbook.worksheets[0]
# 读取单元格
cell = worksheet['A1']
print(cell.value)
# 读取整个行
for row in worksheet.iter_rows(min_row=1, max_row=4, min_col=1, max_col=3):
for cell in row:
print(cell.value)
# 读取整个列
for col in worksheet.iter_cols(min_row=1, max_row=4, min_col=1, max_col=3):
for cell in col:
print(cell.value)
```
3. 写入Excel文件
```python
from openpyxl import Workbook
from openpyxl.utils import get_column_letter
from et_xmlfile import parse_xml
# 创建一个新的Excel文件
workbook = Workbook()
# 获取第一个工作表
worksheet = workbook.active
# 写入单元格
worksheet['A1'] = 'Hello'
worksheet['B1'] = 'World'
# 写入一整行
row = ['Name', 'Age', 'Gender']
worksheet.append(row)
# 写入一整列
for i in range(1, 6):
col_letter = get_column_letter(i)
column = [f'{col_letter}1', f'{col_letter}2', f'{col_letter}3']
worksheet.column_dimensions[col_letter].width = 15
worksheet.append(column)
# 保存Excel文件
workbook.save(filename='example.xlsx')
```
