  # Variable are used to store data. Variables may be of different type such as string, float, integer etc.
  # Variables are also used to as input from users, and then you can store in its memory.
  # Say for example if you want to save someone's age then you have to just use variable to save e.g. age = 25
  # After using the variable you can use it in the print statement to print age.
  
  age = 25  # just writing 25 means that it's your integer
  print(age)  # you will get answer '25' in the terminal box but if you add quote to age then it will print age
  
  degree = 15.5
  print(degree)  # you will get 15.5 which is your float number so as a result you will 15.5
  
  # You can use quotation marks to print string characters so that you can display.
  name = 'HelloWorld'
  print(name)  # you will answer 'HelloWorld' in the terminal box.
  
  # Try yourself
  number = 0 # change 0 to any number
  characters = 'Change_me'
  print(number)
  print(characters)
  
  # Now say for example I used 2 time the same variable with different variables. Let's check it out.
  python = 22
  python = 'I win.'
  print(python)  # run the program and try it by yourself and check the answer.
  
  # In some cases you need to define variable as a large name so for that you have to use underscore instead of spaces
  two_words = 'First Second'  # as you can see that I have writen 2 words as a variable but in between there is no
  # space I have use underscore so that it can understand as a single variable
  print(two_words)
  
  # Now we will be using boolean in python but remember one thing that python is a case-sensitive langauge so make sure
  # that you write in a proper formate
  is_true = True
  print(is_true)
  is_false = False
  print(is_false)
  # as you can see that I have use true or false as a boolean, but it's a case-sensitive, so you have to capitalize all
  # the characters which has been needed if not that it will prompt with you error you can try it by yourself by
  # changing True or False in above code
