    NameError: name CreateSparkContext is not defined

    SparkContext(conf = sparkConf) print (master=+sc.master) SetLogger(sc) SetPath(sc) return (sc)运行时报错:NameError: name CreateSparkContext is not defined可能是由于对齐问题,主程序使用空格,而函数定义使用了Tab,两个看起来一样,实际上不一样。

    Python作用域与名字空间原理详解

    )try: print(a)except Exception as e: print(e)try: print(b)except Exception as e: print(e)输出结果 3 4 5 name ‘a’ is not defined name ‘b’ is not defined python动态运行时,每个作用域都有三个名字空间:由局部变量组成的local名字空间,由全局变量组成的global python的global名字空间是动态的,即每遇到一个赋值语句(def与class也属于赋值语句),global名字空间都可能发生变化。 = 2f()输出结果 name ‘a’ is not defined 2 函数f打印全局变量a,a在第9行定义。 在第五行调用f的时候,a不在global名字空间中,所以会输出错误信息,在第十行再次调用函数f时,a已经加入了global名字空间,所以能够打印出a。

    Python常见十六个错误集合,你知道

    4.NameError: global name ‘time’ is not defined这个问题是我在调用函数time.time()用来计算时间损耗时,使用的函数时报错的,具体解决方案很简单,只要在代码开头加上 5.NameError: global name ‘datetime’ is not defined解决方案同上,from datetime import datetime6.NameError: global name ‘math’ is not defined解决方案同上,import math7.Python中出现类似ascii之类的报错这一类问题主要是在Python代码中有中文输入,这个解决方案是在代码开头加上 8.NameError: global name ‘listdir’ is not definedimport os这里需要注意几个问题,如果直接使用import os的时候,那么调用是就需要写成os.listdir 10.NameError: name ‘reload’ is not defined这个是如果小伙伴们修改了自己写的module,在重载module时可能会出现的一个问题,解决方法还时很简单import

    ABAP,Java和JavaScript的local class

    , which makes sense since this ADD method in local class is not visible to outside consumers.? ************** ENDMETHOD.ENDCLASS.(3) if an event handler in a given program is not intended to be reused by other programs, it could be defined as a local class within the program it is used – in this case it is not necessary to define a global class as event handler.There are lots of such examples in ALV be used outside the class where it is defined.?
