sudo add-apt-repository ppa:jonathonf/python-3.6 

sudo apt-get updatesudo apt-get install python3.6 

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

   Finally switch between the two python versions for python3 via command:

sudo update-alternatives --config python3

python3 -V

  , gnome-terminal won’t launch after step 3, a workaround is running following commands to recreate the symlink:

sudo rm /usr/bin/python3sudo ln -s python3.5 /usr/bin/python3

整库

    # mysql> create database miantiao

# mysql> use your_database_name; # mysql> source file.sql;

Export:

mysqldump -u username –-password=your_password database_name > file.sql

Import:

mysql -u username –-password=your_password database_name < file.sql

Another way to import dump files when source <filename> doesn't work is to do the following:

Dump

~> mysqldump --user=<user> --password=<password> <db_name> > <export_file_name>.sql

Import

> mysql -u 
     
       -p 
       
       
         mysql> USE 
        
         ; (if you didn't already select) mysql> \. ~/
         
          .sql
