Difference between the use of double quote and quotes in python
Single quotes vs. double quotes in Python
So I am now learning python, and was creating a function. What is the difference between using ' and ". I will create a sample function below to exemplify my question.
def question(variable):
print variable
now what is the difference between calling
question("hello")
and
question('hello')
they both print hello, but why can I use both? Is it just because python is flexible? I was confused because ' is usually used for chars where as " is for strings for java right?

Both are equal and what you use is entirely your preference.
As far as the char vs string thing is concerned, refer to the Zen of Python, (PEP 20 or import this)
Special cases aren't special enough to break the rules.
A string of length 1 is not special enough to have a dedicated char type.
Note that you can do:
>>> print 'Double" quote inside single'
Double" quote inside single
>>> print "Single' quote inside double"
Single' quote inside double
" is useful when you have ' into the string and vice versa
Python does not have that restriction of single quotes for chars and double quotes for strings.
As you can see here the grammar explicitly allows both for strings.
