How to insert white space after every number in python?-CodePudding

I have a file with data like this

01000000000
00000010000
...

00000100000
10000000000

I want to convert it to

0 1 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 1 0 0 0 0
...

0 0 0 0 0 1 0 0 0 0 0
1 0 0 0 0 0 0 0 0 0 0

How should I do it?

Thanks

This snippet does it.

with open("path.txt", 'r') as file:
    lines = file.readlines()

arr = []
for line in lines:
    arr.append(' '.join(line.strip())   "\n")
    
print(arr)

with open("path.txt", 'w') as file:
    file.writelines(arr)

Read each line from the file removing any trailing whitespace. Use ' '.join() to intersperse spaces between each character. Save all the lines in a list.

Open the file for writing and output all lines from the list.

FILENAME = 'path.txt'

with open(FILENAME) as data:
    outlines = [' '.join(line) for line in map(str.rstrip, data)]

with open(FILENAME, 'w') as data:
    print(*outlines, sep='\n', file=data)
