As we learned in the previous page, Python syntax can be executed by writing directly in the Command Line
Indentation refers to the spaces at the beginning of a code line.
Where in other programming languages the indentation in code is for readability only, the indentation in Python is very important.
Python uses indentation to indicate a block of code.
if 5 > 2:
print("Five is greater than two!")
Python will give you an error if you skip the indentation:
Syntax Error:
if 5 > 2:
print("Five is greater than two!")
The number of spaces is up to you as a programmer, the most common use is four, but it has to be at least one.
if 5 > 2:
print("Five is greater than two!")
if 5 > 2:
print("Five is greater than two!")
You have to use the same number of spaces in the same block of code, otherwise Python will give you an error:
Syntax Error:
if 5 > 2:
print("Five is greater than two!")
print("Five is greater than
two!")
In Python, variables are created when you assign a value to it:
Variables in Python:
x = 5
y = "Hello, World!"
Python has no command for declaring a variable.
You will learn more about variables in the Python Variables chapter.
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:
Comments in Python:
#This is a comment.
print("Hello, World!")
Insert the missing part of the code below to output "Hello World".
("Hello World")
