Local variables are defined within a function and cannot be accessed outside it. A variable is assumed to be local unless explicitly declared as global using the global keyword.Example:var1 = "Python" def func1(): var1 = "PHP" print("In side func1() var1 = ",var1) def func2():...
输入并运行print(revoscalepy.__version__)以返回版本信息。 你应该会看到 9.2.1 或 9.3.0。 可以在服务器上使用其中任一版本的revoscalepy。 输入一系列更复杂的语句。 此示例使用rx_summary针对某个本地数据集生成摘要统计信息。 其他函数用于获取示例数据的位置,以及为本地 .xdf 文件创建数据源对象。
