为什么报错TypeError
源代码from tkinter import *
from pandas import read_csv
def create(label):
scale = Scale(
root, from_=1, to=100, orient=横向, length=550, label=label,
command=update
)
globals() = scale
def update(v):
global count
draw('Sun', v)
count += 1
def draw(planet, v):
r = radius * v / scale
canvas.create_oval(0, 0, r, r, fill=color)
横向 = HORIZONTAL
root = Tk(className='Solar system scale')
root.geometry('600x775')
root.resizable(False, False)
canvas = Canvas(root, width=600, height=600, bg='black')
canvas.place(x=0, y=0)
create('大小')
create('距离')
scale大小.place(x=25, y=625)
scale距离.place(x=25, y=700)
count = 0
编号范围 = range(1, 10) # 太阳+水金地火木土天海
data = read_csv('data.csv', index_col=0)
color = data['color']
radius = data['radius']
distance = data['distance']
# 600像素 = 海王星距离
scale = distance['Neptune'] / 600 # 这是1像素代表的距离
update(114)
root.mainloop()

谢谢
刚开始还以为是radius为float64的问题，查了一大堆资料没用{:10_257:} 歌者文明清理员 发表于 2023-1-31 12:54
