Reserved keywords are special words in Python that have predefined meanings and cannot be used as variable, function, or class names. They are crucial for the language's syntax and structure.
Here's a complete list of Python keywords:
False class finally is return
None continue for lambda try
True def from nonlocal while
and del global not with
as elif if or yield
assert else import pass
break except in raise
Understanding Reserved Keywords:
- Syntax: These keywords are essential for defining the structure of Python code. For example,
if
,else
, andelif
control conditional statements. - Functionality: They provide built-in functionality, like
print
for output orinput
for user interaction. - Consistency: Using reserved keywords ensures that Python code is consistent and understandable across different programs.
Examples:
- You cannot use
if
as a variable name because it's a reserved keyword. - Similarly, you cannot create a function called
for
because it's a reserved keyword.
Practical Insights:
- Understanding reserved keywords is crucial for writing correct and functional Python code.
- It's important to avoid using reserved keywords as identifiers to prevent syntax errors.
- Use a code editor with syntax highlighting to help identify reserved keywords.
