如何在maya中使用python2.7定义floatSlider？

import maya.cmds as cmds

window = cmds.window(title="Float Slider Example", widthHeight=(300, 100))

main_layout = cmds.columnLayout(adj=True)

slider = cmds.floatSliderGrp(label="My Float Slider", field=True, min=0, max=1, value=0.5, step=0.1)

def button_clicked(*args):
    slider_value = cmds.floatSliderGrp(slider, q=True, value=True)
    cmds.confirmDialog(title="Slider Value", message="The current slider value is: {}".format(slider_value))

button = cmds.button(label="Get Slider Value", command=button_clicked)

cmds.showWindow(window)

import maya.cmds as cmds

def button_clicked(*args):
    slider_value = cmds.floatSliderGrp(slider, q=True, value=True)
    cmds.confirmDialog(title="Slider Value", message="The current slider value is: {}".format(slider_value))

window = cmds.window(title="Float Slider Example", widthHeight=(300, 100))
main_layout = cmds.columnLayout(adj=True)
slider = cmds.floatSliderGrp(label="My Float Slider", field=True, min=0, max=1, value=0.5, step=0.1)
button = cmds.button(label="Get Slider Value", command=button_clicked)
cmds.showWindow(window)
