python: list access with hash values

Question

I want acces python lists with a hash:

hashtable = []
hashtable.append(132328df455b0028f13bf0abee51a63a: 'foo' )

But on execution it doesn`t accept the hash as an index:

python3 ./hdd/search.py
  File "./hdd/search.py", line 10
hashtable.append(132328df455b0028f13bf0abee51a63a: 'foo' )
SyntaxError: invalid syntax

Is there a possibility to use the list with a hash?

Thanks in advance!

did you mean to use a dictionary? hashtable = {}; hashtable[132328df455b0028f13bf0abee51a63a] = 'foo'? — hiro protagonist

@hiroprotagonist I'd suggest making that an answer. OP could possibly want a list of dicts, but that doesn't seem feasible here with what's been provided. — stevieb

"I want acces python lists with a hash" well, you can't do that. Why don't you just use the hashmap data-structure, the dict? — juanpa.arrivillaga

What doesn't work? How are you accessing it? With what @hiroprotagonist suggested, you'd access the value by looking up the key (as opposed to an index number): print(hashtable['132328df455b0028f13bf0abee51a63a']) — stevieb

the datatype that seems to fit your need seems to be the dictionary. you can use it this way:

hashtable = {}
hashtable[0x132328df455b0028f13bf0abee51a63a] = 'foo'
# or directly:
# hashtable = {0x132328df455b0028f13bf0abee51a63a: 'foo'}

and then access the values like this:

value = hashtable[0x132328df455b0028f13bf0abee51a63a]

note hat 132328df455b0028f13bf0abee51a63a is not a valid python integer; you need to prefix hexadecimal numbers with 0x.
