Question

我正在从384孔板中成像荧光细胞，我的软件输出了格式化的excel数据分析（16行x24列图像变成数据列表，每个孔有2个测量值，约800个数据点）。因为与数据有很多手动交互，所以我想通过获取excel工作表中已索引的信息并将其映射为tkinter网格来自动化我的工作。我要获取数据，将其从列表中格式化回原始的16x24显示。我希望能够与这些数据进行交互，但是作为python的新手，我很难映射这些数据。

我用熊猫读取了数据框，但似乎无法在适当的网格框中显示我的列表。理想情况下，我希望excel列表中的值显示在tkinter网格中的相应单元格上。例如，在我的excel列表[1]：https://imgur.com/a/N8HAtYl中，列出了每个孔的两个数据点。我想从每个单元格中获取值并将它们显示在tkinter中的相应网格中，因此“ A1”值的平均值将映射到网格的第1列第1行，A2将是col 2第1行，A3将是第3行第1行，依此类推。

任何帮助都会很棒，谢谢。

我对熊猫不熟悉，因此我将使用openpyxl进行演示。这可能与大熊猫相似甚至更简单。

from openpyxl import load_workbook
import tkinter as tk

root = tk.Tk()

file = "your_excel_file.xlsx"
wb = load_workbook(file, data_only=True)
ws = wb.active

r = 0
for row in ws:
    c = 0
    for cell in row:
        tk.Label(root,text=cell.value).grid(row=r,column=c)
        c+=1
    r+=1

root.mainloop()

快速使用熊猫代替：

df = pd.read_excel('your_excel_file.xlsx',header=None)

for i, row in df.iterrows():
    c = 0
    for cell in row:
        tk.Label(root, text=cell).grid(row=i, column=c)
        c += 1

拉出Excel行以在tkinter中显示为网格
