Can some please explain the use of three speech marks to make newlines in python and also explain what newlines are?

Question

Thanks for the help

Answer 1

Simply:
New lines will make following text to be written in next line.
print("Alpha\nBeta")
#Output:
Alpha
Beta

Newlines are represented as \n, because they are escape characters. Escape characters often have a special meanings.

Strings created with pairs of 3* " or 3* " will automatically escape all escape characters, such as tabs and newlines.

#Valid:
"""a
b
c"""
#Equals 'a\nb\c'

#Invalid:
"a
b
c"

#Valid:
"a\nb\nc"
Equals 'a\nb\nc'

Deeper meaning of docstrings:
You can use docstrings to make some description to a module, to a class or to a function, that will be displayed, when you execute help(name), when name is the name of the module/class/function whose documentation you want to display.

Example:
def useless_function():
"""This function is does nothing."""

help(useless_function)
#Output:
...

useless_function()
This function does nothing.
