我想根据它们的值为第一列中的行着色 - 一种颜色中的所有相同值(1,1,1为红色,然后2为单独颜色,3,3为其他颜色,4 in另一种颜色等)。 我创建了list2,所以我可以检查list1中的行是否具有相同的值(比较)。
我试过这样的事情:
for rows in sheet.iter_rows():
for cell in rows:
for a, b in zip(mirko, darko):
if a == b:
cell.fill = PatternFill(bgColor="FFC7CE", fill_type = "solid")
else:
color = 'FFBB00'
无。我尝试过dataframe styler,但是styler无法迭代。
有什么想法?非常感谢。

以下内容从某些数据创建数据框,创建openpyxl
ExcelWriter。然后它使用Matplotlib的colourmap为您提供一系列颜色。对于每个唯一值,它从colormap指定下一个值,从红色开始:
import pandas as pd
import openpyxl
from openpyxl.styles import PatternFill
import matplotlib
import matplotlib.cm as cm
import numpy as np
data = [
[1, 'test', 1],
[1, 'test', 2],
[1, 'test', 3],
[2, 'test', 4],
[3, 'test', 5],
[3, 'test', 6],
[4, 'test', 7],
[5, 'test', 8]]
write_path = "output.xlsx"
df = pd.DataFrame(data, columns=["value", "comment", "index"])
unique = np.unique(df['value']).shape[0] + 1
with pd.ExcelWriter(write_path) as writer:
df.to_excel(writer, sheet_name="Sheet1", index=False)
wb = openpyxl.load_workbook(write_path)
ws = wb.get_sheet_by_name("Sheet1")
# Create a color map
tohex = lambda r,g,b,a: '%02X%02X%02X%02X' % (a,r,g,b)
gist_rainbow = cm.gist_rainbow(np.linspace(0, 1, unique))
gist_rainbow = np.array(gist_rainbow * 255, dtype=int)
gist_rainbow = iter([tohex(*gist_rainbow[i,:]) for i in range(unique)])
colours = {}
next_colour = next(gist_rainbow) # get the next colour in the colormap
for cells in ws.iter_rows(min_row=2, min_col=1, max_col=1):
cell = cells[0]
try:
colour = colours[cell.value]
except KeyError:
colours[cell.value] = next_colour
colour = next_colour
next_colour = next(gist_rainbow) # get the next colour in the colormap
cell.fill = PatternFill(start_color=colour, end_color=colour, fill_type='solid')
wb.save(write_path)
这会给你一个Excel电子表格,如:
