标题: python导入文件到列表框

import tkinter as tk

from tkinter import ttk

def load_data():

filename = entry_filename.get()

data = []

with open(filename, 'r') as f:

for line in f:

items = line.strip().split('\t')

data.append(items)

return data

def on_button_click():

data = load_data()

tree.delete(*tree.get_children())

for i, row in enumerate(data, start=1):

    tree.insert("", "end", text=str(i), values=row)

创建主窗口

window = tk.Tk()

创建标签和输入框

label_filename = tk.Label(window, text="文件名:")

label_filename.grid(row=0, column=0)

entry_filename = tk.Entry(window)

entry_filename.grid(row=0, column=1)

创建按钮

button = tk.Button(window, text="加载", command=on_button_click)

button.grid(row=1, columnspan=2)

创建表格和滚动条

tree_frame = ttk.Frame(window)

tree_frame.grid(row=2, columnspan=2)

tree = ttk.Treeview(tree_frame, columns=('col1', 'col2', 'col3', 'col4', 'col5'), show='headings')

tree.column('col1', width=100, anchor='center')

tree.heading('col1', text='列1')

tree.column('col2', width=100, anchor='center')

tree.heading('col2', text='列2')

tree.column('col3', width=100, anchor='center')

tree.heading('col3', text='列3')

tree.column('col4', width=100, anchor='center')

tree.heading('col4', text='列4')

tree.column('col5', width=100, anchor='center')

tree.heading('col5', text='列5')

创建滚动条

vsb = ttk.Scrollbar(tree_frame, orient="vertical", command=tree.yview)

tree.configure(yscrollcommand=vsb.set)

vsb.pack(side="right", fill="y")

tree.pack(side="left", fill="both", expand=True)

设置数据列

data = []

创建下一页按钮

button_next = tk.Button(window, text="下一页", state='disabled')

button_next.grid(row=3, columnspan=2)

运行主循环

window.mainloop()

上面是python原生库
这是第二个源码，这个很垃圾，卡的要死，但是据说是很强大的库

import tkinter as tk

from tkinter import ttk

import pandas as pd

import chardet

def load_data():

filename = entry_filename.get()

with open(filename, 'rb') as f:

result = chardet.detect(f.read())

data = pd.read_csv(filename, sep='\t', encoding=result['encoding'])

return data.values.tolist()

def on_button_click():

data = load_data()

tree.delete(*tree.get_children())

for i, row in enumerate(data, start=1):

    tree.insert("", "end", text=str(i), values=row)

创建主窗口

window = tk.Tk()

创建标签和输入框

label_filename = tk.Label(window, text="文件名:")

label_filename.grid(row=0, column=0)

entry_filename = tk.Entry(window)

entry_filename.grid(row=0, column=1)

创建按钮

button = tk.Button(window, text="加载", command=on_button_click)

button.grid(row=1, columnspan=2)

创建表格和滚动条

tree_frame = ttk.Frame(window)

tree_frame.grid(row=2, columnspan=2)

tree = ttk.Treeview(tree_frame, columns=('col1', 'col2', 'col3', 'col4', 'col5'), show='headings')

tree.column('col1', width=100, anchor='center')

tree.heading('col1', text='列1')

tree.column('col2', width=100, anchor='center')

tree.heading('col2', text='列2')

tree.column('col3', width=100, anchor='center')

tree.heading('col3', text='列3')

tree.column('col4', width=100, anchor='center')

tree.heading('col4', text='列4')

tree.column('col5', width=100, anchor='center')

tree.heading('col5', text='列5')

创建滚动条

vsb = ttk.Scrollbar(tree_frame, orient="vertical", command=tree.yview)

tree.configure(yscrollcommand=vsb.set)

vsb.pack(side="right", fill="y")

tree.pack(side="left", fill="both", expand=True)
