是否有Python函数将1行转换为一列

Question

我做了很多事情，将使用情况数据（见下文）分成几列。

current df:
meterId    Consumption    usage    
1          1000           100
1          900            100
1          800            0
2          2000           500
2          1500           250
2          1250           150
2          1100           100
2          1000           0

我尝试了旋转，移调等操作。

What I want to achieve is the following:

meterId   Usage1 Usage2 Usage3 Usage4 Usage5
1         100    100    0      NAN    NAN
2         500    250    150    100    0
