Python hello world program

Python is a scripting language that runs using a python interpreter. The interpreter converts the program (python text file with “.py” extension) into hardware understandable format.

Let us see a simple hello world program using python language.

# Below code prints 'Hello World!' string.

print('Hello World!')

While we install the python program, it gives a set of executables in which one executable is “python” which generates an interpreter and makes it run on hardware. Below is how we use that executable.

Python 2.7.10 (default, Jul 15 2017, 17:16:57) 
[GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.31)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> print('Hello World!')
Hello World!

Here in the above program, we are using a function called ‘print‘ and a string ‘Hello World!’.

‘print’ is an inbuilt function that prints the string argument. A string is a sequence of characters that are in between single quotes (”), double quotes(“”) or triple quotes(”””).

# Below code prints 'Hello World!' string as well.
# String with triple quotes.
strng = '''Hello World!'''

A simple python program (Hello world example)

# function to print 'Hello World!'.
def greet(text):

# calling function that prints given text
greet("Hello World!")

We save the above code into a file named ‘’ (with .py extension) and run the code using the python executable as shown below.

# Output
Hello World!

Hope this python hello world program helps you to start learning python. Happy Learning!.
