reduce与map函数一样,也属于高阶函数,其原型为reduce(function,sequence),作用是用function对序列进行累计操作,返回的是一个累计值。累计操作不是计数操作,而是对列表里第一个数、第二个数传入function里处理,如function函数为lamda x,y:x+y,即对数x和y相加操作,接下来是使用该结果与第三个数相加,这样来调用funct...

map也支持使用现有的UDF函数,传入的参数是str类型(函数名)或者Function对象,详情请参见函数。 map传入Python函数的实现使用了MaxCompute Python UDF。因此,如果您所在的Project不支持Python UDF,则map函数无法使用。除此以外,所有Python UDF的限制在此都适用。 目前,默认可使用的第三方库(包含C)只有NumPy,第三方库...

从源码中可以看出,add 参数很多,如 level、format、filter、color 等等,我们重点看看 sink 参数 sink : |file-like object|_, |str|, |Path|, |callable|_, |coroutine function|_ or |Handler| An object in charge of receiving formatted logging messages and propagating them to an ...
