When you make a string in Python, but the string shall look like multiple lines in the source code, the following doesn’t work:
id = "line1 " "and line2"
But we can do this trick to make it work:
id = ( "line1 " "and line2 " "and more" )
As long as Python knows something is still on-going (e.g. the parentheses), it concatenates the strings for you.
