Example

In this example, a list variable was created with a value of the same data type. The test_list variable is assigned the value of [2.5,3.5,1]


In this example, a list variable was created with a value of different data types. The test_list variable is assigned the value of [2,True,"Hello"]


create list with item [item] repeated [number] times

Block

Description

Creates a list with a given value repeated a given number of times by the user. The both parameters could contain an operation like "1+1", as long as it returns a value—integer or float. The first parameter can be a string value as well.

Parameters

integer/float/string  value repeated: value that will be repeated in the list
integer  repeats: the number of times the given value will be in the list.

Returns

list: A list containing the given value repeated a given number of times.

Example

In this example, instead of simply putting a number block, the first parameter contains an operation block that will return a number, which is 2. The second parameter contains a number block of 3. Printing test_list will result in [2,2,2].


length of

Block

Description

Returns the length of the list, which is the number of items that are inside the list.

Parameters

None

Returns

int length: The length (number of items in the list) of the list.

Example

After creating the list [1,2,3] and assigning it to the variable test_list, the console will print the length of test_list, which is 3 (three items in the list).


[list] is empty

Block

Description

Returns a boolean value indicating if the list is empty or not (if the list has no items or not).

Parameters

list list variable: a variable that's a list

Returns

boolean  is empty: True if there are items in the list. Otherwise, returns False

Example

In this example, test_list block is attached to the "create empty list" block. The console prints test_list, which is []. Then, the console prints the length of test_list, which is 0. Finally, the console prints whether or not test_list is empty, which is True. These 3 printing statements are ways to verify if the list is indeed empty or not. "is empty" is useful when applying if-statements to it.


In this example, the console prints whether or not test_list is empty, which is False. test_list indeed is not empty since there are items in it.


in list [list] find [occurrence] occurrence of item [item]

Block

Description

Retuns the index (position) of the first/last occurrence of the given item in the given list variable.

Parameters

list list variable: a variable that is a list
occurrence: the first or last occurrence of the item
integer/float/string  item: value of the item

Returns

integer index: The position of the item in the list

Example

In this example, the test_list variable is assigned the value of [1,2,3]. The console prints 2 as the first occurrence of the item "2" in test_list since it is the second item in test_list.

Parameters


list  list variable: A variable that is a list
command: option to whether to get, get and remove, or remove an item from the list
position: The position of the item. (Some options require an integer input like the "#" and "# from end").

Returns

integer/float/string  item: If choosing "get" or "get and remove", the value of the item is returned. If choosing "remove", returns None

Example

In this example, the list variable test_list is created with a value of [100,5,2,3]. For the first and third print statements, undefined is printed since the position numbers are out of range (the positions don't exist) in test_list. 5 and 3 are printed for the second and fourth print statements, respectively, since 5 is in position #2 and 3 is in position #4.



In the example below, the list variable test_list is created with a value of [100,5,2,3]. Then, in order, the items at position #4, position #3, and position #2 are removed from test_list. The console prints test_list, which outputs [100].



In the example below, the list variable test_list is created with a value of [100,5,2,3]. Then, in order, the items at positiong #4, position #3, and position #2 are printed on the console and removed from test_list. The console prints test_list, which outputs [100]. NOTE: "get and removed" option makes the block capable to be attached to a variable block as well.

list sub-list: The sub-list from the given list

Example

In this example, the list variable test_list is created with a value of [23,2,100,5,4,3]. The list variable new_list is created with a value of [23,2,100,5]. This is because the "get sub-list" block gets a portion of test_list from position #1 (23) to position #4 (5).


sort numeric/alphabetic ascending/descending

Block

Description

Returns sorted list based on numerical/alphaetical order and ascending/descending order. This could be attached to a "print" block or a "set variable" block.

NOTE: alphabetical ordering, in programming, is done using the strings' letters' ASCII codes. The uppercase alphabet (A-Z) has ASCII values between 65 and 90, and the lowercase alphabet (a-z) has ASCII values between 97 and 122. This means lowercase alphabet has higher ASCII values than the uppercase alphabet.

Parameters


order type: The way the list is sorted, by alphabetical or numerical order
order: ascending (A-z or smallest to biggest) or descending (z-A or biggest to smallest)

Returns

list sorted list: a sorted list

Example

In this example, a list variable test_list is created with a value of [5,2,3]. The console prints the output of the sorted list from test_list in ascending, numerical order [2,3,5].



In the example below, a list variable test_list is created with a value of ["Zebra","apple","Mouse"]. The console prints the sorted list from test_list in descending alphabetical order, which is ["apple", "Zebra", "Mouse"].



In the example below, a list variable test_list is created with a value of ["Zebra","apple","Mouse"]. The console prints the sorted list from test_list in descending alphabetical order (ignoring case), which is ["Zebra", "Mouse", "apple"]. Ignoring case essentially reads the uppercase letters as lowercase letters, so a lowercase "z" has a greater ASCII value than a lowercase "m" (and lowercase "m" greater than lowercase "a").


make [list from text/text from list] [text/list] with delimiter [value]

Block

Description

If choosing the "list from text" option, the block internally splits the given text into parts based on the given delimiter and returns a list. For example, the string "12!23!5!" with a delimiter of "!" will be converted to [12,23,5]. If choosing the "text from list" option, the block internally joins the given list's items based on the given delimiter and returns a string. For example, the list [12,3,5] with a delimiter of "--" will be converted to "12--3--5".

Parameters

string/list string/list variable: the variable, which is a list or text, that will be converted into a string or list.
string delimiter: a string of characters that will join a list's items or split the text's contents.

Returns

string/list converted string or list: a list (or string) that is the result of the conversion of the given string (or list) with the given delimiter.

Example

In this example, the string "14,2,1" will be converted into a list with the "," delimiter. The list variable test_list will be set to this conversion. The console will print test_list, which is [14,2,1].

In this example, the list variable test_list will have value of [23,2,100]. The string variable test_string will have the value of "23--2--100" since it's set to the value of the converted list of test_list with the -- delimiter.


reverse [list]

Block

Description

Returns a list with the reversed order of the given list.

Parameters

list list variable: the list variable that will its order reversed

Returns

list reversed list: a reversed list of the given list

Example

In this example, the list variable test_list has a value of [23,2,100,5,4,3]. Then, the list variable new_list is set to the value of a reversed list of test_list. The console will print [3,4,5,100,2,23].
