Tkinter 标签显示不正确

Question

我正在练习 API 集成到我的一些项目中，我想尝试练习一些词典。提取天气数据和长话短说：尝试创建简单的 tkinter 应用程序，它将向我展示这本词典中的内容。

import tkinter as tk

window = tk.Tk()

sample = {"location": {"name": "Belgrade", "region": "Central Serbia", "country": "Serbia", "lat": 44.8, "lon": 20.47, "tz_id": "Europe/Belgrade", "localtime_epoch": 1643798038, "localtime": "2022-02-02 11:33"}, "current": {"last_updated_epoch": 1643796900, "last_updated": "2022-02-02 11:15", "temp_c": 2.0, "temp_f": 35.6, "is_day": 1, "condition": {"text": "Sunny", "icon": "//cdn.weatherapi.com/weather/64x64/day/113.png", "code": 1000}, "wind_mph": 0.0, "wind_kph": 0.0, "wind_degree": 228, "wind_dir": "SW", "pressure_mb": 1009.0, "pressure_in": 29.8, "precip_mm": 0.0, "precip_in": 0.0, "humidity": 100, "cloud": 0, "feelslike_c": -1.4, "feelslike_f": 29.6, "vis_km": 10.0, "vis_miles": 6.0, "uv": 1.0, "gust_mph": 9.2, "gust_kph": 14.8, "air_quality": {"co": 317.1000061035156, "no2": 13.399999618530273, "o3": 45.400001525878906, "so2": 10.5, "pm2_5": 11.399999618530273, "pm10": 15.600000381469727, "us-epa-index": 1, "gb-defra-index": 1}}}

for j, k in sample['location'].items():
    tk.Label(window, text=j).grid(column=0)
    tk.Label(window, text=k).grid(column=1)

window.mainloop()

但是，当我完成它时，我发现了一些奇怪的事情：键：值对以之字形顺序添加，而不是一个接一个地添加。例如： 'name' 键的位置是 (0,0)。但是它的值放在 (1, 1) 处。我可以将所有内容放在单列中，这样它就会得到某种排序和可读性，但是，我很想了解为什么输出是这样的。 Strange pattern

您可以使用变量设置行。我在这个例子中称它为 row：

import tkinter as tk

window = tk.Tk()

sample = {"location": {"name": "Belgrade", "region": "Central Serbia", "country": "Serbia", "lat": 44.8, "lon": 20.47, "tz_id": "Europe/Belgrade", "localtime_epoch": 1643798038, "localtime": "2022-02-02 11:33"}, "current": {"last_updated_epoch": 1643796900, "last_updated": "2022-02-02 11:15", "temp_c": 2.0, "temp_f": 35.6, "is_day": 1, "condition": {"text": "Sunny", "icon": "//cdn.weatherapi.com/weather/64x64/day/113.png", "code": 1000}, "wind_mph": 0.0, "wind_kph": 0.0, "wind_degree": 228, "wind_dir": "SW", "pressure_mb": 1009.0, "pressure_in": 29.8, "precip_mm": 0.0, "precip_in": 0.0, "humidity": 100, "cloud": 0, "feelslike_c": -1.4, "feelslike_f": 29.6, "vis_km": 10.0, "vis_miles": 6.0, "uv": 1.0, "gust_mph": 9.2, "gust_kph": 14.8, "air_quality": {"co": 317.1000061035156, "no2": 13.399999618530273, "o3": 45.400001525878906, "so2": 10.5, "pm2_5": 11.399999618530273, "pm10": 15.600000381469727, "us-epa-index": 1, "gb-defra-index": 1}}}

row = 0
for j, k in sample['location'].items():
    tk.Label(window, text=j).grid(column=0,row=row)
    tk.Label(window, text=k).grid(column=1,row=row)
    row += 1

window.mainloop()
