unpack 列表的语法把列表中的三个函数抽出来，重新给他们命名为 f1, f2, f3# 也就是说，# locals[...
You can also remove the parentheses in the line where you unpack your tuple. For instance: defpowers(x):square = x*x cube = square*xreturnsquare, cubes,c = powers(5)print(s)print(c) works correctly. Note the lack of parentheses in the line where we unpack the results into variables...
45:11# 12 ~ 16 字节是 py 文件的大小print( struct.unpack("<I", data[12: 16])[]) # 22结果和我们分析的一样，前 16 字节是固定的，而 16 个字节往后就是 PyCodeObject 对象，并且是序列化之后的，因为该对象显然无法直接存在文件中。import marshalwith open("__pycache__/tools.cpython-312....
a,=struct.unpack('i',bytes) 1. 注意,unpack返回的是tuple 所以如果只有一个变量的话: bytes=struct.pack('i',a) 1. 那么,解码的时候需要这样 a,=struct.unpack('i',bytes) 或者 (a,)=struct.unpack('i',bytes) 1. 如果直接用a=struct.unpack('i',bytes),那么 a=(12.34,) ,是一个tuple而不...
Packing a tuple: fruits = ("apple","banana","cherry") Try it Yourself » But, in Python, we are also allowed to extract the values back into variables. This is called "unpacking": Example Unpacking a tuple: fruits = ("apple","banana","cherry") ...
We already know that we can unpack each of the things in each of these key-value tuples into two variables (say thing and count):>>> for item in things.items(): ... thing, count = item ... print(thing, count) ... ducks 2 lamps 3 chairs 0 ...
