Before delving into this chapter, it’s crucial to recall how to run a fundamental Python program, whether you’re using Thonny or Atom. If you need a quick refresher, you can refer to the previous chapter for a step-by-step guide.<\/p>\n\n\n\n

In the world of Python, there’s a saying that ‘everything in Python is an object.’ As we progress, we’ll dive deeper into this concept and gain a more profound understanding of it. But, let’s begin by exploring the fundamentals of data types.<\/p>\n\n\n\n

In the last chapter, we laid the foundation by creating a simple program with just one command. Now, let’s build upon that knowledge and take the next steps in our Python journey.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Our single line program was as follows<\/p>\n\n\n\n

print(2+3)<\/mark><\/p>\n\n\n\n

The program’s output was ‘5<\/b>‘ , which is\u00a0 <\/span>the addition of the two numbers \u00a0 \u00a0 <\/span>‘ 2+3<\/b>.’<\/p>\n\n\n\n

Let’s create a new Python program named ‘variables.py’ and add a few more commands to it:<\/p>\n\n\n\n

    \n
  1. Open your Python development environment, whether it’s Thonny or Atom.<\/li>\n\n\n\n
  2. In the editor, create a new Python file and save it as ‘variables.py’ within your designated project folder.<\/li>\n\n\n\n
  3. Add the following lines of code to your ‘variables.py<\/strong>‘ file:<\/li>\n<\/ol>\n\n\n\n
    print(2 + 3)\nprint('2 + 3')<\/mark><\/pre>\n\n\n\n
      \n
    1. Save the file.<\/li>\n\n\n\n
    2. Now, run the program by clicking the ‘Run’ or ‘Execute’ button in Thonny or using the terminal\/command prompt if you’re in Atom.<\/li>\n\n\n\n
    3. Observe the program’s output<\/li>\n<\/ol>\n\n\n\n
      <\/div>\n\n\n
      \n
      \"\"<\/a><\/figure>\n<\/div>\n\n\n
      <\/div>\n\n\n\n
      This is how Python executes the individual commands.<\/p>\n\n\n\n
      Line No<\/span><\/td>Input<\/span><\/td>Output<\/span><\/td><\/tr>
      1<\/span><\/td>print (2+3)<\/span><\/td>5<\/span><\/td><\/tr>
      2<\/span><\/td>print (\u20182+3\u2019)<\/span><\/td>2+3<\/span><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
      The quotes (‘\u00a0 \u00a0 <\/span>‘) in the print command change how Python interprets what’s inside the ‘print’ command.\u00a0<\/span><\/p>\n\n\n\n
      At line no 1, the input is treated as numbers, and Python has proceeded to execute the addition’s mathematical operation.<\/p>\n\n\n\n
      At line no 2, the input is treated as characters, including the addition sign, and prints them out as mere words.<\/p>\n\n\n\n
      Within the inverted commas (quotes ‘  <\/span>‘), the characters’ input is technically called a ‘String.’<\/p>\n\n\n\n
