Delimiters are the characters that start and stop a certain part of code.
Strings, or groups of characters, can be delimited in 4 ways in Python:
'Single Quotes' (apostrophe)
"Double Quotes" (quotation marks)
'''Triple Single Quotes''' (multi-line strings)
"""Triple Double Quotes""" (multi-line strings)
Each of these strings is the same in the memory of Python interpreter but:
Multi-line strings are easiest to code with the multi-line delimiters:
It's not so important when TO use each, but more important when NOT to use each.
For instance, if you need an ' in your output, it's simple to use " for a delimiter:
Or if you need " in your output, use ':
print('The cat said, "meow"')
But trouble ensues if you need both in your string such as printing the phrase:
He said, "It's your fault."
You could accomplish this with triple-single quotes:
print('''He said, "It's your fault."''')
or using Escape Characters (special sequences of characters to print single characters)
print("He said, \"It's your fault\"")
For instance notice the \" in code prints " in output.
