With a bit of googling, you'll find that this is a Python Bytecode file.  Bytecode instrunctions: `https://sceweb.sce.uhcl.edu/helm/WEBPAGE-Python/documentation/python_tutorial/lib/bytecodes.html`
**These are the most important instructions:**  LOAD_FAST references a local argument, which can be interpreted as a function parameter.  LOAD_CONST references a variable outside the function scope.  BUILD_SLICE creates a Python slice, e.g. array[4:6]  BINARY_SUBSCRIPT essentially performs indexing, e.g. array[4]  COMPARE_OP performs a boolean comparison, e.g. ==  POP_JUMP_IF_FALSE - not certain on what this means, but it can be reasonably guessed that this will execute a return statement forthe function if the previous expression evaluated to false  
With that in mind, let's try to analyze the first function:
```15           0 LOAD_FAST                0 (flag) 	--> string: flag              2 LOAD_CONST               0 (None)              4 LOAD_CONST               1 (6)              6 BUILD_SLICE              2		--> [None:6]              8 BINARY_SUBSCR				--> flag[None:6]             10 LOAD_CONST               2 ('TCP1P{')             12 COMPARE_OP               3 (!=) 	--> flag[None:6] != 'TCP1P{'             14 POP_JUMP_IF_FALSE       38             16 LOAD_FAST                0 (flag) 	--> string: flag             18 LOAD_CONST               3 (-1)             20 LOAD_CONST               0 (None)             22 BUILD_SLICE              2		--> [-1:None]             24 BINARY_SUBSCR				--> flag[-1:None]             26 LOAD_CONST               4 ('}')             28 COMPARE_OP               3 (!=) 	--> flag[-1:None] != '}'             30 POP_JUMP_IF_FALSE       38```
With this first function analyzed, it is easy to now analyze the rest of the functions by hand!A short summary of each relevant function follows:
```15:	flag[:6] == 'TCP1P{'	flag[-1:] = '}'18:	flag[6:10] == 'byte'21:	flag[10, 15, 18] = chr(98) = '_'24:	flag[11:15] == 'code'27:	flag[11] == flag[19] --> c30:	flag[12] == ord(flag[20]) - 6 --> u33:	ord(flag[16]) != 105 --> i	ord(flag[17]) != 115 --> s36:	flag[19] != 'H' (overrides 27)39:	ord(flag[20]) == 117 --> u (confirms 30)42:	ord(flag[21]) != ord(flag[2]) - 10 --> F45:	flag[22] != lower(flag[0]) --> t48:	flag[22] == flag[23] --> t```
*Note: I essentially treated != and == as doing the same thing, telling us what should be at that index.
