Wrap a word in python

Question

I want to wrap the string below:

string = 'ABCDEFGHIJKLIMNOQRSTUVWXYZ'

With the max width as 4, for instance I want this output:

I created this function:

def wrap(string, max_width):
    i = max_width
    while True:
        string = string[:i] + '\n' + string[i+1:]
        if i >= len(string):
            break
    return string

if __name__=='__main__':
    string = 'ABCDEFGHIJKLIMNOQRSTUVWXYZ'
    print(wrap(string, 4))

But the outputs was:

May you help me, please?

Consider using the [textwrap](https://docs.python.org/3.9/library/textwrap.html) in the standard library. — snakecharmerb, Dec 31 '19 at 18:23

In general when learning to code, you want to master the art of debugging. In this case, where you have a loop, you want to see what is happening in each iteration of the loop. — Arya, Dec 31 '19 at 18:27

The following should work:

def wrap(string, max_width):
    return '\n'.join(string[i:i+max_width] for i in range(0,len(string),max_width))

Or they could use the built in textwrap module and call textwrap.wrap() – Bayleef Dec 31 '19 at 18:40
True, but based on the question I thought that g3rno was trying to create their own wrap function. – 3ddavies Dec 31 '19 at 18:43

Try this:

string = 'ABCDEFGHIJKLIMNOQRSTUVWXYZ'

for i in range(0, len(string), 4):
    print(string[i:i+4])

Output

ABCD
EFGH
IJKL
IMNO
QRST
UVWX
YZ

Just replace the i+1 with i like this:

string = string[:i] + "\n" + string[i:]

Another try with regular expression:

def wrap(string, max_width):
    return '\n'.join(re.findall(f'.{{1,{max_width}}}',string))
