My first project as a beginner

[lil_e]

Hi.

I'm trying to learn Python by reading the book called "Automate the boring stuff", and have written my first project which I have copied from the book.

It's supposed to copy text from a clipboard, and add (*) in front of each line, but when I run it nothing happens. I have copied a random text on a website with Ctrl+C. Not sure if this is the right way to do it
Can someone tell me what I'm doing wrong?

My code:

#! python 3
# bulletPointAdder.py - Adds Wikipedia bullet points to the start
# of each line of text on the clipboard.

import pyperclip
text = pyperclip.paste()

# Separate lines and add stars.
lines = text.split('\n')
for i in range(len(lines)):     # loop through all indexes in the "lines" list
    lines[i] = '* ' + lines[i]  # add star to each string in "lines" list
text = '\n'.join(lines)
pyperclip.copy(text)

Error:
Python 3.9.13 (tags/v3.9.13:6de2ca5, May 17 2022, 16:36:42) [MSC v.1929 64 bit (AMD64)] on win32

The code dos not output anything only manipulate text that is in Clipboard in Windows
If add print(text) will see the output.

# py_copyclip.py
import pyperclip
text = pyperclip.paste()

# Separate lines and add stars.
lines = text.split('\n')
for i in range(len(lines)):
    lines[i] = '* ' + lines[i]
text = '\n'.join(lines)
print(text)
pyperclip.copy(text)

Copy this text.

Output:
hello world
12345

Run code,will now see the output.

G:\div_code
λ python py_copyclip.py
* hello world
* 12345

Paste from clipboard (Ctrl+v)

Output:
* hello world
* 12345

Why the error post? I don't see any error and your code works fine for me.

After running your program, paste the clipboard contents into something. This is what shows up after I copied your program to the clipbaord, pasted to VSCode, ran it, and then did a paste here:

Output:
* import pyperclip
* text = pyperclip.paste()
*  
* # Separate lines and add stars.
* lines = text.split('\n')
* for i in range(len(lines)):     # loop through all indexes in the "lines" list
*     lines[i] = '* ' + lines[i]  # add star to each string in "lines" list
* text = '\n'.join(lines)
* pyperclip.copy(text)

My God, it's full of stars!

The code could also be written using str.replace()

import pyperclip

text = "*" + pyperclip.paste().replace("\n", "\n*")
pyperclip.copy(text.rstrip("*"))

Or using an f'string and a comprehension.

import pyperclip

lines = (f'*{line}' for line in pyperclip.paste().split("\n")
pyperclip.copy("\n".join(lines))

And probably many, many more.
