set range, range( )
The ___ function returns the number of items of an object
len( )

Infinite Loops
the ____ function can be used to define a list within another list

adds a value to an existing variable
append( )
N __ lists can be used to arrange data in hierarchical structiures
nested

int( )
Constructs a floating number from an integer or float
float( )
Constructs a string from a wide variety of data types
str( )
How are conditions executed?
by if and else commands
Multiple if statements can be chained together using the ____ command
elif
using the ____ command helps make the code more efficient
elif
a ___ structure is a method of organizing and storing data so it can be accessed and acted upon easily
data structure
Data structures in Python include ___, _____ and lit
dictionary, tuple
A versatile and dynamic data type. Can hold different types of data simultaneously. The values are numerically indexed starting at 0
List
A list’s indexes are used for
List manipulation
Update/add value:
listName{ index ] = newValue
Delete value
del listName[ index ]
two additional ways to change lists are
append( ) and remove( )
immutable sequence of python objects and are created simply by writing values separated by commas
Tuple
A python ____ is a collection of items
dictionary
Dictionaries are identified by ____
curly brackets
___ is used with an item’s name for deletion
del
Data structure can hold other data structures
Nested Data Structures
A python data type, identified by “” A collection of indexed characters
String
Multiple strings can be aggregated to a single string. Performed by using the + operator
String Concatenation
The slicing structure is ______________.
string[ start:end:step ]
separates a string and arranges it as a list
Split( )
