PYTHON - Coggle Diagram

- - - - myVariableName = "John"
    - - MyVariableName = "John"
    - - my_variable_name = "John"
    - - If we use the global keyword, the variable belongs to the global scope
        
        Variables that are created outside of a function (as in all of the examples in the previous pages) are known as global variables.
    - - If we want to specify the data type of a variable, this can be done with casting.
        
        Example : x = str(3) # x will be '3'
    - - A variable name must start with a letter or the underscore character
      - A variable name cannot start with a number
      - A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )
      - Variable names are case-sensitive (age, Age and AGE are three different variables)
      - A variable name cannot be any of the Python keywords.
    - - If we create a variable inside a function, this variable will be local, and can only be used inside the function.
        
        To create a global variable inside a function, you can use the global keyword.
  - - - A will not overwrite a
  - - - Data balikan dari input akan selalu berbentuk string, misalkan yang diinput adalah integer maka hasilnya akan selalu menjadi string, jika ingin menadikan bentuk integer kita menggunakan fungsi convert to integer
- - - - a = """Lorem ipsum dolor sit amet,
        consectetur adipiscing elit,
        sed do eiusmod tempor incididunt
        ut labore et dolore magna aliqua."""
        print(a)
  - - - b = "Hello, World!
        print(b[2:5])
  - - - txt = "We are the so-called \"Vikings\" from the north."
- - - - We can convert to Float using function
        x = 5
        y = float(x)
        print(y)
  - - - j is imajiner
- - - - List items are ordered, changeable, and allow duplicate values.
        List items are indexed, the first item has index [0], the second item has index [1] etc.
      - append
        
        to add list on the last item
      - extend list
        
        To append elements from another list to the current list, use the extend() method.
      - remove
        
        to remove items from list
      - pop()
        
        Remove Specified Index
      - clear
        
        The clear() method empties the list.
      - List Comprehension
        
        List comprehension offers a shorter syntax when you want to create a new list based on the values of an existing list.
      - sort()
        
        List objects have a sort() method that will sort the list alphanumerically, ascending
      - sort(reverse = True):
        
        To sort descending
- - - - age = 36
        txt = f"My name is John, I am {age}"
        print(txt)
