I am doing this coding challenge in Python and in the challenge, the input is given as lines of integers separated by space in a file called "input.txt" like so:
3 3 1
1 0 3 1
2 2
Each line represents different part of an input, like the first line is width and height of a grid and number of walls in it, second line are coordinates of start and end and third are coordinates of a specific wall. How would you read the file, so you will at the end get a list, where each line is a separate item in the list, like so:
input = [[3, 3, 1], [1, 0, 3, 1], [2, 2]]
# the numbers are integers
Thanks for answer
with open('input.txt', 'r') as infile:
# iterating through a file will naturally iterate line-by-line
# str.split() will split on spaces naturally, and we can convert to int for each value
# thus, a nested list comprehension
inp = [[int(i) for i in line.split()]
for line in infile]
