Python

Hello!
Please tell me how can I write the following program. Change has files 1.mp4 and 2.mp4. We need to write a python program that plays 1.mp4, and when the spacebar is pressed, immediately pauses 1.mp4 and starts playing 2.mp4. When the second file ends, the first continues to play from the same point.
Any hints will be glad.
Thank you.
