    Python Comments

  • Comments can be used to explain Python code.
  • Comments can be used to make the code more readable.
  • Comments can be used to prevent execution when testing code.
    • Creating a Comment
  • Comments in Python start with #. In the moment that python is going to se # anything behind is going to be ignored.
    • Example:
    #This is a comment
    print("Hello, World!")
    So if we put # the python is going to ignore the text,mesage or anything else that is going to wrrite the programmer
    and in our case the sentence"#This is a comment" is going to be ignore from python.

    Python Numbers

    There are three numeric types in Python:
  • int
  • float
  • complex
    • Variables of numeric types are created when you assign a value to them:
    Example:
  • x = 1 # int
  • y = 2.8 # float
  • z =z = 1j # complex
    • To verify the type of any object in Python, use the type() function:
    Example:
  • print(type(x))
  • print(type(y))
  • print(type(z))
