我试图实施以下法典,该法典载于Bash文。

NUMBER=600
LOSS_RATE=0,3
TOT_PKT=100

test=$(python -c "from math import ceil; print ceil($NUMBER * 500.0)")
test2=$(python -c "from math import ceil; print ceil($NUMBER * $LOSS_RATE)")
echo $test
echo $test2

我收到以下文件:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
TypeError: ceil() takes exactly one argument (2 given)
300000.0

The first Python-command is executed, but the second causes the given TypeError. How do I do to resolve this?

最佳回答

辩论分离器是<条码>,作为自<条码>起的术语。 因此,如果你使用<代码>。 LOSS=0.3 一切工作都应做到:

> NUMBER=600
> LOSS_RATE=0.3
> python -c "from math import ceil; print ceil($NUMBER * $LOSS_RATE)"
180.0

问题在于手稿。 <代码>echo而不是python -c 页: 1

> echo "from math import ceil; print ceil($NUMBER * $LOSS_RATE)"
from math import ceil; print ceil(600 * )

您从来不定义<代码>LOSS_RATE。 然而,这导致了SyntaxError。 由于你有不同的错误,因此,如<代码>LOSS_RATE,就是指含有 com的物品。
