24
Q

What are the 6 categories of tokens?

A
  1. Keywords
  2. Identifiers
  3. Literals
  4. Operators
  5. Delimiters
  6. Comments
25
Keywords are __ words that have __ meaning in Python.
reserved, special
26
Keywords can be used as identifiers.
False. They can't be used as identifiers because keywords are reserved words.
27
Types of keywords can be...
flow control, data types, classes and objects, and modules and packages.
28
Examples of keywords.
if, else, for, while, def, class, import, try, except.
29
Identifiers are names...
given to variables, functions, classes, and modules.
30
__ starts with a letter or an _ and can contain letters, __, or __.
Identifiers, underscores, numbers, underscores
31
Identifiers must begin with...
1. A letter of the English language 2. A non-English letter (a or π) 3. Underscore 4. Dollar sign
32
Identifiers can begin with a digit.
False.
33
What casing convention does Python follow?
snake_case.
34
Describe snake_case.
It is where all words are lowercase and separated by an underscore.
35
snake_case is used for...
variables, function, and modules.
36
What casing convention do class names use?
PascalCase/UpperCamelCase.
37
Describe PascalCase.
It is where several words are joined together, and the first letter of every word is capitalized.
38
Describe PascalCase.
It is where several words are joined together, and the first letter of every word is capitalized.
39
Literals represents...
constant values.
40
Literals can only be strings.
False. Literals can be different data types (i.e., numbers, strings, etc.)
41
Literals cannot be "none".
False.
42
"None" represents...
the absence of values.
43
They are symbols used to perform operations on values.
Operators.
44
Delimiters are characters used to...
separate different parts of a Python program (e.g., “()”, “{}”, etc.).
45
These start with a "#" for single lines, or " "' " for multiple lines.
Comments.
46
Comments are texts...
ignored by the Python interpreter.
47
It is a token used to explain code or provide documentation.
Comments.
48
This defines how a class can be accessed.
Access specifier.
49
It is a crucial aspect of the language's syntax and is used to define code blocks and control the flow of execution.
