请编制一个计算y=f(x)的程序,其中: y = x x<1 y = -1/x - 1 1<=x<10 y = 5x-11 x>=10 **输入提示信息**:"Please input x:\n" **输入数据格式**:"%f" **输出数据格式**:"y=%.2f\n" 程序运行示例: Please input x: 4 y=-1.25

以下是Python的实现代码:
```python
x = float(input("Please input x:\n"))
if x < 1:
y = x
elif x >= 1 and x < 10:
y = -1 / x - 1
else:
y = 5 * x - 11
print("y=%.2f" % y)
```
运行示例:
```
Please input x:
4
y=-1.25
```
