change textfile to a matrix format

amirayat

Dears,
I have a text file that is regular like a matrix, I want to have a program to read it in matrix format to knows rows and columns. ofcourse this file is mixture of digits and words somthings like this.
[1 qw 23 rg 4 4
1 w 4 32 s 9]
Help me ,
Best wishes,
Ayat.

I assume the values are seperated by a space and a newline equals a new matrix line.

Also I will only write this in psuedo code since I don't feel like coding atm, yet I do want to answer :)

Expand|Select|Wrap|Line Numbers

 
f = open("file.txt","r")

matrix = ()

counter = 0

line = f.readline()

while line <> "":

   matrix[counter] = line.split(" ")

   line = f.readline()

   counter = counter + 1

What does it do:
First read a file, create a few variables and loop through the file and split the line and add it to the matrix in a new row

Since you have not shown an effort to code it yourself, I won't provide a complete solution. This uses a list comprehension:

Expand|Select|Wrap|Line Numbers

 >>> s = "[1 qw 23 rg 4 4\n1 w 4 32 s 9]"

>>> [item.split() for item in s.split('\n')]

[['[1', 'qw', '23', 'rg', '4', '4'], ['1', 'w', '4', '32', 's', '9]']]

>>>
