如果语句总是运行，即使不是真的[关闭]

Question

我想在系统使用超过400瓦时设置powercap。我尝试使用简单的if语句来做到这一点，但if语句也在当前功率为256瓦时运行

我的代码看起来像这样

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

当我低于400瓦特nothing to do时，我看到了这样的输出，但实际上我得到了这个输出Current Power : 247 Watts

All done.

nothing to do

或者你有其他建议我怎么做？

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")
