Basic Syntax In Python

As we learned in the previous page, Python syntax can be executed by writing directly in the Command Line:

>>> print("Hello, World!")
Hello, World!

Or by creating a python file on the server, using the .py file extension, and running it in the Command Line:

C:\Users\Your Name>python myfile.py

Python Indentations

Where in other programming languages the indentation in code is for readability only, in Python the indentation is very important. Python uses indentation to indicate a block of code.

Example

if 5 > 2:
  print("Five is greater than two!")

Python will give you an error if you skip the indentation:

Example

if 5 > 2:
print("Five is greater than two!")

Comments

Python has commenting capability for the purpose of in-code documentation. Comments start with a #, and Python will render the rest of the line as a comment:

Example

Comments in Python:
.
#This is a comment 
print("Hello, World!")

Docstrings

Python also has extended documentation capability, called docstrings. Docstrings can be one line, or multiline. Python uses triple quotes at the beginning and end of the docstring:

Example

Docstrings are also comments:

"""This is a 
multiline docstring."""
print("Hello, World!")
