粘贴时自动去掉python码前的数字

Question

当我阅读电子书或网站时，我显然可以复制并粘贴 python 代码，而不是低效地编写所有代码。但是有时 python 代码的格式在实际的 python 代码行前面有一个 数字、一个句点和一个 space，不知有没有technique/tools自动删除？例如，来自...

68. # File name: floatlayout.py
69. 
70. from kivy.app import App
71. from kivy.uix.floatlayout import FloatLayout

到...

# File name: floatlayout.py

from kivy.app import App
from kivy.uix.floatlayout import FloatLayout

 def remove_spaces(file_path):
     with open(file_path) as myfile, open('newfile.py', mode='w+') as newfile:
        for line in myfile:
            idx = line.find(' ')
            if idx < 0 or idx + 1 >= len(line) or is_int(line.strip()[:-1]):
                newfile.write('\n')
                continue

            newfile.write(line[idx+1:] + '\n')

def is_int(str):
    try: int(str)
    except: return False

    return True
