Comments in PYTHON

 
Programs must contain comments.
The comments explain the sequence of instructions.
Comments help maintain the program.
Comments are written on a line using #
Comments are written on multiple lines using "" "and" ""
Comments help the programmer who takes over a program from another programmer who has left the team.
The comments clarify everything.
Comment programs are the best.
Comments are written anywhere.
Comments precede instruction sequences.
Comments are written after each instruction.
Comments must be visible.
