def <function-name>() 定義資料集的 Python 函式。 如果未設定name參數,則會將<function-name>當做目標資料集名稱使用。 query 會傳回 Spark 資料集或 Koalas DataFrame 的 Spark SQL 陳述式。 使用dlt.read()或spark.read.table()從相同管線中定義的資料集執行完整讀取。 若要讀取外部數據集,請使用 函式spa...
We investigate the convergence rate of the solutions of one and two-dimensional Poisson-type PDEs where the Dirac delta function, representing the forcing term, is approximated by several expressions. The goal is to see if the solution to a Poisson's equation converges when solved by a ...

python 中,可以使用 time.gmtime(0) 来获取系统历元,返回的数据类型为 struct_time(time.gmtime() 和 struct_time 的用法将在后文介绍);可以使用 time.time() 返回自 epoch 到现在经过的秒数(带小数的秒 fractional seconds)。 <1> time.time() → float:返回浮点数,表示从 epoch 到现在经历的秒数。
Tracking changes incurs a round of one or more delta function calls. If you use any query parameter (other than $deltatoken and $skiptoken), you must specify it in the initial delta request. Microsoft Graph automatically encodes any specified parameters into the token portion of the @odata.ne...
