How to read matrix from an ascii file-CodePudding

I am trying to read ascii text file as a matrix. The ascii file has 512 entries which are treated as rows and after each breakline character, a new row starts. It looks something like

I tried using

with open('24_5.asc', 'r') as f:
l = [[int(num) for num in line.split(',')] for line in f]
print(l)

but that gives an error

invalid literal for int() with base 10: '\n'

Any help will be appreciated

CodePudding user response：

Your problem here is that when you split a line the last element of the list returned will be a string "\n", which cannot be converted to int. So Removing it with [:-1] should work:

with open('24_5.asc', 'r') as f:
    l = [[int(num) for num in line.split(',')[:-1]] for line in f]
    print(l)
