Study Notes
Checking the Length of a List in Python
- The valid method to check the length of a list in Python is by using the
len()function.
Inserting an Element at a Specific Index in a List in Python
- The correct way to insert an element at a specific index in a list in Python is by using the
insert()method.
Data Types in Python
- A list is a data type that is used to store multiple items in a single variable, and is ordered, changeable, and allows duplicate values.
Creating a Tuple in Python
- The correct way to create a tuple in Python is by enclosing the elements in parentheses
().
Characteristics of Tuples in Python
- Tuples are ordered and unchangeable data types.
Accessing Tuple Elements in Python
- The output of the code
thistuple = ('apple', 'banana', 'cherry') print(thistuple[2])ischerry, which is the element at index 2 in the tuple.
Data Types in Python
- A set is a data type that allows duplicates and is unordered.
Accessing Dictionary Elements in Python
- The output of the code
thisdict = {'brand': 'Ford', 'model': 'Mustang', 'year': 1964} print(thisdict['color'])is an error, because the key'color'does not exist in the dictionary.
Calling a Function with Arguments in Python
- The correct way to call the function
my_functionwith argumentsfname='John'andlname='Doe'is by using the syntaxmy_function(fname='John', lname='Doe').
Function Definitions in Python
- The output of the code
my_function('Emil')depends on the definition of the functionmy_function. - When you call the function
my_functionwith only one argument, it will execute the function with that argument, but the behavior depends on the function definition.
Using * before the Parameter Name in a Function Definition
- The purpose of using
*before the parameter name in a function definition is to allow the function to accept a variable number of arguments.
Sending Arguments to a Function using Key-Value Syntax in Python
- In Python, you can send arguments to a function using the key-value syntax, such as
my_function(key1='value1', key2='value2').
Function Calls with Lists in Python
- The output of the code
my_function([1, 2, 3])depends on the definition of the functionmy_function.
The Return Statement in a Function
- The
returnstatement in a function is used to exit the function and return a value to the caller.
The Pass Statement in Python Function Definitions
- The purpose of the
passstatement in Python function definitions is to act as a placeholder, allowing the function to be defined without a body, and avoid aSyntaxError.
