以下是处理此问题的一种方法:
import xlrd
book = xlrd.open_workbook("sample.xls", formatting_info=True)
sheets = book.sheet_names()
print "sheets are:", sheets
for index, sh in enumerate(sheets):
sheet = book.sheet_by_index(index)
print "Sheet:", sheet.name
rows, cols = sheet.nrows, sheet.ncols
print "Number of rows: %s Number of cols: %s" % (rows, cols)
for row in range(rows):
for col in range(cols):
print "row, col is:", row+1, col+1,
thecell = sheet.cell(row, col)
# could get 'dump', 'value', 'xf_index'
print thecell.value,
xfx = sheet.cell_xf_index(row, col)
xf = book.xf_list[xfx]
bgx = xf.background.pattern_colour_index
print bgx

此函数返回元组中单元格背景的 RGB 值。
def getBGColor(book, sheet, row, col):
xfx = sheet.cell_xf_index(row, col)
xf = book.xf_list[xfx]
bgx = xf.background.pattern_colour_index
pattern_colour = book.colour_map[bgx]
#Actually, despite the name, the background colour is not the background colour.
#background_colour_index = xf.background.background_colour_index
#background_colour = book.colour_map[background_colour_index]
return pattern_colour

JMax 建议的解决方案仅适用于xls文件,不适用于xlsx文件。这引发了一个NotImplementedError: formatting_info=True not yet implemented. Xlrd库仍未更新以适用于xlsx文件。因此,您Save As每次都必须更改格式,这可能对您不起作用。
这是xlsx使用openpyxl库的文件的解决方案。A2是我们需要找出其颜色代码的单元格。
import openpyxl
from openpyxl import load_workbook
excel_file = 'color_codes.xlsx'
wb = load_workbook(excel_file, data_only = True)
sh = wb['Sheet1']
color_in_hex = sh['A2'].fill.start_color.index # this gives you Hexadecimal value of the color
print ('HEX =',color_in_hex)
print('RGB =', tuple(int(color_in_hex[i:i+2], 16) for i in (0, 2, 4))) # Color in RGB
