#31991 — turn list of letters into an array of integers

Here's some example code. The input is a list which is a "matrix" of letters:
   a  b  a
   b  b  a

and I'd like to turn this into a Python array:

  1 2 1
  2 2 1

so 1 replaces a, and 2 replaces b. Here's the code I have so far:

>>> L=['a b a\n','b b a\n']
>>> s=' '.join(L)
>>> seq1=('a','b')
>>> seq2=('1','2')
>>> d = dict(zip(seq1,seq2))
>>> # Define method to replace letters according to dictionary (got this from http://gomputor.wordpress.com/2008/09/27/search-replace-multiple-words-or-characters-with-python/).
... def replace_all(text, dic):
...     for i, j in dic.iteritems():
...         text = text.replace(i, j)
...     return text
... 

>>> seq = replace_all(s,d)
>>> print seq
1 2 1
 2 2 1

>>> seq
'1 2 1\n 2 2 1\n'

My question is how can I turn "seq" into a python array?

Thanks
Michael

Something like this perhaps?:

>>> alpha = ('a', 'b')
>>> numeric = ('1', '2')
>>> L = ['a b a\n', 'b b a\n']
>>> s = ' '.join(L)
>>> d = dict(zip(alpha, numeric))
>>> list_ = [d[c] for c in s.strip('\n').split()]
>>> list_
['1', '2', '1', '2', '2', '1']

I'd suggest, if this is what you're referring to:

x = seq.split('\n  ')
array_list = [ ]
next_3_d_array = []
range_of_seq = len(seq)
for num in range(0,range_of_seq):
       if num % 3 != 0:
               next_3_d_array.append(num)
       if num % 3 == 0:
                   array_list.append(next_3_d_array)
                   next_3_d_array = [ ]

Of course, if you want these to be ints, then you can either change the format of your int list, or map(int, list_) if you don't have control over it.

Ugh, I'm tired. Shouldn't map it, the conversion should be done in the list comprehension to avoid a needless second list iteration.

K, I'm going to sleep now. :P

You mean a Python list. The datatype Python calls an `array` is very
different and relatively uncommonly used.
Although, confusingly, Python's lists are implemented using C arrays
rather than linked lists.

I'd say you're asking the wrong question. The better question is "Why
wasn't the result a list in the first place?". Many transformations
are cumbersome to express over just strings, which is why the first
job of most programs is to parse their input into a more convenient
structure that is suited to their main task(s).

This (along with some other improvements) leads to a better, somewhat
different program/algorithm:

letter2number = {'a': 1, 'b': 2}
with open("path/to/file.txt", "r") as f:
    result = [[letter2number[letter] for letter in
line.strip().split()] for line in f]

If it's safe to assume that the correspondence between the letters and
numbers isn't completely arbitrary, some further improvements are also
possible.

Some relevant docs:
http://docs.python.org/library/stdtypes.html#string-methods
http://docs.python.org/tutorial/datastructures.html#list-comprehensions

Cheers,
Chris

P.S.: I'm guessing you obtained `L` from file.readlines() or similar;
it is worth noting for future reference that the readlines() method is
considered somewhat deprecated.

The list in python is a list of valid python objects.
For the number crunching part, please use  arrays in numarray and scipy.

Thanks to everyone lots of great comments are actionable suggestions. 

My intension is to used the numpy/scipy packages to solve the task at hand. I agree that there's no point in loading a file into a format which only needs to be converted right after loading. But I'm new to Python the f.readline(s) command, according to the 2.7.3 tutorial and manual, is pretty much all there is for file i/o. If, as you indicated, f.readlines() is deprecated then what should I use instead? I'm using ver. 2.6 on Linux (it's a bit dated, I know).

Just iterate over the file directly using a for-loop (e.g. `for line
in some_file:`). Each iteration yields one line of the file. I used a
very minor variation of this approach in my code (a list comprehension
is just syntax sugar for a for-loop).

Cheers,
Chris

But I'm new to Python the f.readline(s) command, according to the 2.7.3 tutorial and manual, is pretty much all there is for file i/o. If, as you indicated, f.readlines() is deprecated then what should I use instead? I'm using ver. 2.6 on Linux (it's a bit dated, I know).

No need to strip() if you are going to split on whitespace:

>>> line = " a b c \n"
>>> line.split() == line.strip().split()
True

Lest the new idiom takes on while you are bravely fighting the immortable 
readlines() ;)

If you are going to replace single characters (letters) with single 
characters (digits), use maketrans and translate.

 >>> 'a b c'.translate(str.maketrans('abc', '123'))
'1 2 3'

If you're using .split() then you don't need to use .strip() as well:

     result = [[letter2number[letter] for letter in line.split()] for 
line in f]

Not so sure what you mean by an "array of integers".

>>> def z(s):
...     a = s.splitlines()
...     b = [e.split() for e in a]
...     for row in range(len(b)):
...         for col in range(len(b[row])):
...             b[row][col] = ord(b[row][col]) - ord('a')
...     return b
...     
>>> z('a b a\n b b a')
[[0, 1, 0], [1, 1, 0]]
>>> 
>>> # or
>>> table = {'a': 111, 'b': 222}
>>> 
>>> def z2(s, table):
...     a = s.splitlines()
...     b = [e.split() for e in a]
...     for row in range(len(b)):
...         for col in range(len(b[row])):
...             b[row][col] = table[b[row][col]]
...     return b
...     
>>> z2('a b a\n b b a', table)
[[111, 222, 111], [222, 222, 111]]
>>> 
>>> # note
>>> z('a\n b b b b b\n a a')
[[0], [1, 1, 1, 1, 1], [0, 0]]

I wasn't entirely sure about that either. I assumed given the subject that it was just a 1-D array and could then be accessed by arr[(y * width) + x].

Wasn't there a Monty Python sketch where a man carrying a parrot in a cage 
comes into a shop full of stuffed animals and complains: No, I don't admire 
the taxidermist for making that parrot look like it were alive -- that beast 
bit me!
