Flashcards
An object that can iterate through a sequence, but which does not provide list operators and methods.
The result of calling a built-in function zip; an object that iterates through a sequence of tuples.
The operation of treating a sequence as a list of arguments.
The operation of assembling a variable-length argument tuple.
An assignment with a sequence on the right side and a tuple of variables on the left. The right side is evaluated and then its elements are assigned to the variables on the left.
An immutable sequence of elements.
A statement like global that tells the interpreter something about a variable.
A boolean variable used to indicate whether a condition is true.
A statement that declares a variable name global.
A variable defined outside a function. Global variables can be accessed from any function.
A computed value stored to avoid unnecessary future computation.
A diagram that shows every frame created during the execution of a program, with an arrow from each caller to each callee.
A list (or other sequence) with a single element.
A statement that (deliberately) raises an exception.
A dictionary operation that takes a value and finds one or more keys that map to it.
A dictionary operation that takes a key and finds the corresponding value.
A type that has a hash function. Immutable types like integers, floats and strings are hashable; mutable types like lists and dictionaries are not.
A function used by a hashtable to compute the location for a key.
The algorithm used to implement Python dictionaries.
A way of performing a computation.
An object that appears in a dictionary as the second part of a key-value pair. This is more specific than our previous use of the word “value”.
An object that appears in a dictionary as the first part of a key-value pair.
In a dictionary, another name for a key-value pair.
The representation of the mapping from a key to a value.
A mapping from keys to their corresponding values.
A relationship in which each element of one set corresponds to an element of another set.
A character or string used to indicate where a string should be split.
A circumstance where two or more variables refer to the same object.
The association between a variable and its value.
Being the same object (which implies equivalence).
Having the same value.
Something a variable can refer to. An object has a type and a value.
A processing pattern that traverses a list and selects the elements that satisfy some criterion.
A processing pattern that traverses a sequence and performs an operation on each element.
A processing pattern that traverses a sequence and accumulates the elements into a single result.
A statement that updates the value of a variable using an operator like +=.
A variable used in a loop to add up or accumulate a result.
A list that is an element of another list.
One of the values in a list (or other sequence), also called items.
A sequence of values.
