Can we write either double quote or single quote within the print function

Answer 1

Yes, but you have to be consistent and use the same type at the beginning and at the end.

Answer 2

Yes, you can use both.
You can even use triple double quote or triple single quote.
But you have to consider the beginning and the end must be the same.

Example:
print('Hello World!')
print("Hello World2!")
print('''Hello
World3
!''')
print("""
Hello
World4!""")

Answer 3

No problem either one
