使用openpyxl库可以读取单元格字体颜色,具体步骤如下:
1. 导入openpyxl库和颜色模块
```python
from openpyxl import load_workbook
from openpyxl.styles import colors
from openpyxl.styles import Font, Color
```
2. 打开excel文件,获取工作簿和活动表单对象
```python
wb = load_workbook('example.xlsx')
sheet = wb.active
```
3. 循环遍历单元格,获取每个单元格的字体颜色
```python
for row in sheet.iter_rows():
for cell in row:
font = cell.font
color = font.color
if isinstance(color, colors.Color):
r, g, b = color.rgb
print(f'The color of cell {cell.coordinate} is RGB({r}, {g}, {b})')
else:
print(f'The color of cell {cell.coordinate} is {color.theme}')
```
上述代码中,我们使用了`iter_rows()`方法来遍历所有行,然后在每一行中遍历所有单元格。对于每个单元格,我们获取它的字体对象和颜色属性,并判断颜色是否为RGB格式。如果是,就打印出RGB值,否则打印出颜色的主题。
需要注意的是,如果单元格的字体颜色是自定义的颜色,则无法获取其RGB值,只能获取到颜色的主题。
完整代码示例:
```python
from openpyxl import load_workbook
from openpyxl.styles import colors
from openpyxl.styles import Font, Color
wb = load_workbook('example.xlsx')
sheet = wb.active
for row in sheet.iter_rows():
for cell in row:
font = cell.font
color = font.color
if isinstance(color, colors.Color):
r, g, b = color.rgb
print(f'The color of cell {cell.coordinate} is RGB({r}, {g}, {b})')
else:
print(f'The color of cell {cell.coordinate} is {color.theme}')
```
