In Python, small anonymous (unnamed) functions can be created with lambda keyword. Lambda forms can be used as an argument to other function where function objects are required but syntactically they are restricted to a single expression. A function like this: def average(x, y): return (x +...

Unlike C, Python functions do not need to be fully defined before the program runs. More generally, defs are not evaluated until they are reached and run, and the code inside defs is not evaluated until the functions are later called. Because function definition happens at runtime, there’s...
# 函数对象(变量)与普通对象(变量)一样,在函数内部定义,随函数调用而产生, # 调用结束而销毁,所以只能在函数内部调用 def outer(): print('outer run') a = 10 def inner(): a = 100 print('inner run') print(a) inner() #print(a) #报错 ,此a未定义 outer() 输出: outer runinner run...

Because we have to covert the whole Python definition into multiple Python task in dolphinscheduler, and all of the seperated Python task will be executed in the different Python process, so we need to separate not only the python function code, but also the all variables and the imported modu...
