2013年9月10日 · I am new to coding Python and I just can't seem to understand what a Def function is! I have looked and read many tutorials on it and I still don't quite understand. Can somebody explain to me what it is, what I use it for, and give me some examples. For the examples please make them easy and understandable for a newb to Python. Thanks!

2013年1月17日 · funcdef: 'def' NAME parameters ['->' test] ':' suite The optional 'arrow' block was absent in Python 2 and I couldn't find any information regarding its meaning in Python 3. It turns out this is correct Python and it's accepted by the interpreter: def f(x) -> 123: return x I thought that this might be some kind of a precondition syntax, but:

To access a 'def' from within a class, you need to first make an object of that class, and than do object.nameofdef(), which than executes that 'def' on the object, while if you just make a 'def' outside of a class, it can be executed on whatever you want, but without it being linked to a certain object (not sure if this is explaining a lot ...

Suppose you add a new api in the dll, then the linker looks at your .def file genearate the ordinal number for the ne wapi such that the ordinal numbers for the old apis are intact.

2016年7月11日 · You may want to explore the notion of namespaces.In Python, the module is the natural place for global data:. Each module has its own private symbol table, which is used as the global symbol table by all functions defined in the module.

2012年7月24日 · def add2(n1, n2): print 'the result is:', n1 + n2 # prints but uses no *return* statement def add2_New(n1, n2): return n1 + n2 # returns the result to caller Now when I call them: print add2(10, 5) this gives: the result is: 15 None The first line comes form the print statement inside of add2().

2022年1月6日 · def factorial(n): return 1 if n == 0 else n * factorial(n-1) One line lambda function approach: (although it is not recommended to assign lambda functions directly to a name, as it is considered a bad practice and may bring inconsistency to your code. It's always good to know. See PEP8.) factorial = lambda n: 1 if n == 0 else n * factorial(n-1)

2010年10月28日 · Variables inside def main are local, while those outside it are global. This may introduce a few bugs and unexpected behaviors. But, you are not required to write a main() function and call it inside an if statement. I myself usually start writing small throwaway scripts without any kind of function.
