    \n
  • The Python function is defined by a def statement. The syntax looks like this: def function-name (Parameter list): statements, i.e. the function body. The parameter list contains none or more parameters. Parameters are known as arguments, if the function is called.<\/li>\n
  • A python function is a \u201ccallable\u201d (which just means something you can invoke) that repeats a set of steps that you pre-define.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
    \n
    \n
      \n
    • \n
        \n
      • Function blocks begin with the keyword def followed by the function name and parentheses ( ( ) ).<\/li>\n
      • Any input parameters or arguments must be placed within these parentheses. Now you will define the parameters within the parentheses.<\/li>\n
      • The initial statement of a function is optional \u2013 the documentation string of the function (docstring).<\/li>\n
      • The code block within every function starts with a colon (:) and is indented.<\/li>\n
      • The statement return [expression] exits a function, optionally passing back an expression to the caller. The return statement with no arguments is the similar as return none.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
