python - 即使不为 true，If 语句也始终运行

Question

我想在系统使用超过 400 瓦时设置功率上限。我尝试使用简单的 if 语句来做到这一点，但当当前功率为 256 瓦时也会运行 if 语句

我的代码如下

a=400

node1 = Node(0, 0, 0, 0)
node1.getPowerUsage()
node1.getGpuPowerUsage()
node1.getCpuPowerUsage()
node1.setPowercap()


if(node1.getCpuPowerUsage() > a):
    node1.setPowercap()

else:
    print("nothing to do")

node1.getCpuPowerUsage() 的输出看起来像这样

print node1.getCpuPowerUsage()
277.54

当功率低于 400 瓦时，我希望看到这样的输出 nothing to do 但实际上我得到这个输出 Current Power : 247 Watts

Enabled persistence mode for GPU 00000000:35:00.0.
Enabled persistence mode for GPU 00000000:5B:00.0.
Enabled persistence mode for GPU 00000000:CD:00.0.
Enabled persistence mode for GPU 00000000:AA:00.0.
All done.
Power limit for GPU 00000000:35:00.0 was set to 125.00 W from 250.00 W.
Power limit for GPU 00000000:5B:00.0 was set to 125.00 W from 250.00 W.
Power limit for GPU 00000000:CD:00.0 was set to 125.00 W from 250.00 W.
Power limit for GPU 00000000:AA:00.0 was set to 125.00 W from 250.00 W.
All done.
nothing to do

或者您对我如何做到这一点还有其他建议吗？

将值转换为 float 。

例如:

a=400

node1 = Node(0, 0, 0, 0)
node1.getPowerUsage()
node1.getGpuPowerUsage()
node1.getCpuPowerUsage()
node1.setPowercap()


if(float(node1.getCpuPowerUsage()) > a):
    node1.setPowercap()
else:
    print("nothing to do")
