  3. In the editor, type the following code:
  1. Click the "Run" button to execute the code.
  2. The output of the code should be the following:

When writing your first programme, remember the following additional points:

  • Verify that Python is being used at the proper version. The Python version being used by the online compiler should be stated.
  • You might wish to start with a straightforward programme like the one above if you are new to Python. You may start writing more sophisticated programmes as you get more comfortable with the language.
  • You may learn Python using a variety of online resources. You may ask questions via forums, tutorials, and other resources.

Debugging on the Fly

Python code may be debugged online in a manner similar to how it is done locally. The same debugging tools and methods are available. To debug Python code using an online compiler, follow these steps:

  • Determine the bug: You may accomplish this by reading the error notice or by going line by line through the code.
  • Place a breakpoint: A line of code that the debugger will stop executing is known as a breakpoint. This enables you to check the state of the programme and the values of the variables.
  • Traverse the code: You may check the values of variables at each stage while the debugger runs the code line by line.
  • Fix the bug: Once you have identified the bug, you can fix it and then run the code again.

Python Syntax

Loops (for loop, while loop, do-while loop):

  1. For loop: A list, tuple, or string of items can be iterated through using the for loop. A for loop has the following syntax:

Any iterable object, including a list, tuple, or string, may be used as the sequence. Each element of the sequence will be given its own assignment to the item variable. Each element in the sequence will have the indented section of code executed.

For example, the following code will print the numbers from 0 to 9:

The range() method provides a list of numbers that, by default, begin at 0 and increase by 1 each time. The range() method will in this situation provide a list of integers ranging from 0 to 9, inclusive.

  1. While loop: Used to continually run a piece of code while a predetermined condition is true. The following is the syntax for a while loop:

A Boolean statement that may only be evaluated as True or False constitutes the condition. The code block will be run if the condition is True. As long as the condition is True, the code will keep running.

For example, the following code will print the numbers from 0 to 9, but only if the number is even:

The initial value of the i variable is 0. While i is less than 10, the while loop will keep running. The if clause determines whether the integer is even. The number will be printed if it is. Then a one is added to the i variable.

Conditional statements (if/else):

The if statement in Python is used to run a block of code if a specific requirement is satisfied. An if statement has the following syntax:

Any expression that evaluates to a Boolean value, such as True or False, can be used as the condition. The code block indented below the if statement will be run if the condition is satisfied. The code block will not run if the condition is false.

If the if statement's condition is false, the else statement is used to run a block of code. The else statement has the following syntax:

The else clause is not required. If it is not utilised and the if statement's condition is false, no code will be run.

An illustration of an if statement is given below:

The criterion in this instance is number% 2 == 0. If the number is even, this statement evaluates to True; otherwise, it evaluates to False. The code block that is indented below the if statement will run if the number is even, printing the message "The number is even." The code block will not be executed if the number is odd.

An illustration of an if statement and an else statement is as follows:

In this illustration, the code block indented beneath the if statement will be performed if the number is even, printing the message "The number is even." The code block that is indented under the else statement will be performed if the number is odd, printing the message "The number is odd."


The syntax for defining a function in Python is:

  • def is the keyword used to define a function.
  • function_name is the name of the function.
  • parameters are the arguments that the function takes.
  • Body of the function is the code that the function executes.

The return statement is used to return a value from a function. The syntax is:

  • return is the keyword used to return a value from a function.
  • value is the value that is returned from the function.

Here is an example of a Python function that creates the add() function, which accepts two inputs and returns the total of those two numbers:
