Python Keywords
All Python keywords cannot be used for variable names:
Python is a case-sensitive language and Python keywords are case- sensitive.
Please take note that these 3 keywords - False, None, True all of them start with an uppercase character and not
a lowercase character:
False
None
True
Variable names are also case-sensitive:
False is not the same as false
False cannot be used as a variable name
false can be used as a variable name
The Python keyword False, which starts with an uppercase F, is not the same as lowercase false.
Python keyword False cannot be used as a variable name, but lowercase false can be used as a variable name.
Tracing Variables
As the value of a variable changes throughout our program because new values are constantly assigned to it, we
can use the print() function to trace the value of our variables.
The print() function can be used for debugging purposes whereby we need to know what went wrong in our
program - and one way to find out is to trace how the value of our variables changes in the course of our program.
