Python Forum - Coordinates from a text file

Hi i have to create a 2d game of sorts and to start it i need to create a function which reads in a text file and creates a list from each line.
and then from that line those characters are separated.
for example if the text file has
******F****
*****W*****
it needs to become
[****F****, *****W*****] and then
[[*,*,*,F,*,*,*,*],[*,*,*,*,W,*,*,*,*]]

from what ive heard you need to use a while loop with a nested while loop to achieve this but i just have no idea where to start.

Check https://docs.python.org/3.3/tutorial/inp...ting-files

Use list(line_read_file) to convert into list

sorry i have to create a another list within that list if that makes sense

In Python sequences are iterable. Also a str is iterable.
A list, tuple, set, dict, ..., consumes iterables.

greeting = "Hello World"
print(list(greeting))

Output:
['H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd']

So you can use this, to split the chars of a line, which represents the row (y coordinates).

text = """
******F****
*****W*****
""".strip()
# the text has a leading '\n'
# and a tailing '\n'
# strip removes whitespaces from left and right side of a str
# also a newline is interpreted as whitespace.

matrix2d = [list(line.strip()) for line in text.splitlines()]
# iterate over lines, which are the rows
# make a list from each row, which represents the columns


# if you want to transpose the 2d matrix:
matrix2d_transposed = list(zip(*matrix2d))

another way to sort of say what i need is
ls = ['string one' , 'string two']
ls2 = [[s,t,r,i,g, ,o,n,e], [,s,t,r,i,n,g, ,t,w,o]]

**X**
* *
**Y**

thats what the board looks like i need to put it in cells if that makes sense

text = '''******F****
*****W*****'''
print ("text =",text)
ls = text.splitlines()
print ("ls =",ls)
ls2 = [[letter for letter in line] for line in ls]
print ("ls2 =",ls2)

could i apply this to a text file ill send you the code i have for that

def read_lines(filename):
    try:
        file = open(filename, 'r')
        readfile = file.readlines()
        return list(readfile)

    except FileNotFoundError:                                            
        return "{} does not exist!".format(filename)

and the file the code opens contains this
**X**
* *
**Y**

Strings are sorted by lexicographical order (also known as alphabetical order).

Here an example with some German words:

Output:In [70]: sorted(random.sample(words, 10))
Out[70]:
['Bakterienzüchtung',
 'Chrzowitz',
 'Generalfragen',
 'Latzrock',
 'Prognosemodell',
 'Reliefklischee',
 'chaotisieren',
 'dreireihig',
 'erwünschtestes',
 'kampfunfähigem']

In [71]: sorted(random.sample(words, 10))
Out[71]:
['Ablehnen',
 'Attenschweiler',
 'Bewahrheitung',
 'Filzgarn',
 'Rollin',
 'Schneckengrün',
 'Textilgürtelreifen',
 'anpflanzender',
 'herausgestrichenen',
 'kostenschonendes']

words = ["Ca", "ca", "cA"]
print(sotred(words))

Output:
['Ca', 'cA', 'ca']

Python is "seeing" the chars as values and they are compared as values

words = ['Ca', 'cA', 'ca']
chars_as_int = [tuple(ord(c) for c in word) for word in sorted(words)]
print(chars_as_int)

Output:
[(67, 97), (99, 65), (99, 97)]

Python sorts by first letter, then second letter, ...

Do you want to sort via alphabet?

Uppercase letters are smaller in their value as Lowercase letters.
