Good example, Rob, of how some people make what I consider RELIGIOUS edicts
that one can easily violate if one wishes and it makes lots of sense in your
example.
Let me extend that. The goal was to store a character string consisting of
multiple lines when printed that are all left-aligned. Had you written:
HelpText = """
Left click: Open spam
...
Shift + Right click: Fry egg
"""
Then it would begin with an extra carriage return you did not want. Your
example also ends with a carriage return because you closed the quotes on
another line, so a \ on the last line of text (or moving the quotes to the end
of the line) would be a way of avoiding that.
Consider some alternatives I have seen that are in a sense ugly and may involve
extra work for the interpreter unless it is byte compiled once.
def someFunc():
HelpText =
"Left click: Open spam" + "\n" +
"Shift + Left click: Cook spam" + "\n" +
...
Or the variant of:
HelpText = "Left click: Open spam\n"
HelpText += " Shift + Left click: Cook spam\n"
...
Or perhaps just dumping the multi-line text into a file beforehand and reading
that into a string!
def someFunc():
The backslash is not looking like such a bad idea! LOL!

def someFunc():

The initial backslash aligns the first line with the others (in a fixed font of
course).
