Python clipboard Block Movement

This has never been found in the Linux block mobile editor.

Because the code you may copy on the internet is like this, you need to move the entire code four characters forward and write such a program to implement this function.

>>> from sqlalchemy import Column, Integer, String>>> class User(Base):...     __tablename__ = 'users'......     id = Column(Integer, primary_key=True)...     name = Column(String)...     fullname = Column(String)...     password = Column(String)

Step

1. Copy Clipboard data to file

2. read data from File

3. Block move

4. Save File

5. copy file data to clipboard

Sudo apt-Get install xclip in Ubuntu

# Copy data to clipboard
Cmd = 'cat to.txt | xclip-selection clipboard'
OS. popen (CMD)
