dtseqlib 1.1

Sequence data type.

Description

This library adds the new data format: sequence. Sequences has 2 attributes: Name, Count. Name - Name of the sequence element. Count - Count of elements. Sequence presented in matrix format. One element of the sequence looks how:

[name = "Apple", count = 2].

Methods

sequence.init(seq=None) - Class constructor.

• seq receives the matrix in the form below.

[[_first element_], [_second element_], ..., [_n element_]]

[!CAUTION] Don't use any data type except integer in count attribute!

sequence.append(name=None, count=0) - Element append function.

• name receives name of the element.
• count receives the count of current element.

> seq = dtseqlib.Sequence([["Autumn", 1]])
> seq.append("Element", 2)
> print(seq.get())

[["Autumn", 1], ["Element", 2]]

[!CAUTION] Don't use any data type except integer in count attribute!

sequence.insert(name=None, count=0, index=0) - Inserts the element by index.

• name receives name of the element.
• count receives the count of current element.
• index receives the insert index.

> seq = dtseqlib.Sequence([["Autumn", 1]])
> seq.insert("Element", 2)
> seq.insert("Spring", 5, 2)
> print(seq.get())

[["Element", 2], ["Autumn", 1], ["Spring", 5]]

[!CAUTION] Don't use any data type except integer in count and index attributes!

sequence.delete(index=0) - Deletes the single element by index.

• index receives the remove index.

> seq = dtseqlib.Sequence([["Autumn", 1], ["Spring", 2]])
> seq.delete(1)
> print(seq.get())

[["Autumn", 1]]

[!CAUTION] Don't use any data type except integer in index attribute!

sequence.clip(indexes=[-1, 0]) - Deletes the multiple elements in array range.

• _indexes* receives the min and max index in list for cliping.

> seq = dtseqlib.Sequence([["Autumn", 1], ["Spring", 2]])
> seq.clip([0, 1])
> print(seq.get())

[]

[!CAUTION] Don't use any data type except integer in every element in indexes attribute! Use only from min to max sort!

sequence.get() - Return list of the elements in sequence.

sequence.scan(index=0) - Return single element from sequence array.

• index receives the element index.

> seq = dtseqlib.Sequence([["Autumn", 1], ["Spring", 2]])
> print(seq.scan(1))

["Spring", 2]

[!CAUTION] Don't use any data type except integer in index attribute!

sequence.multiple_scan(indexes=[-1, 0]) - Return multiple elements from sequence array by range.

How clip, but instead of deleting.

[!CAUTION] Don't use any data type except integer in every element in indexes attribute! Use only from min to max sort!

sequence.scan_cbn(count=0) - Return list of the elements with define count.

> seq = dtseqlib.Sequence([["Autumn", 1], ["Spring", 2]])
> print(seq.scan_cbn(2))

["Spring", 2]

[!CAUTION] Don't use any data type except integer in count attribute!

sequence.scan_nbc(name=None) - Return list of the elements with define name.

How scan_cbn, but with name.

sequence.get_bwc(count=0) - Get matrix of elements (blocks) with define count.

> seq = dtseqlib.Sequence([["Winter", 1], ["Spring", 2], ["Autumn", 1]])
> print(seq.bwc(1))

[["Winter", 1], ["Autumn", 1]]

[!CAUTION] Don't use any data type except integer in count attribute!

sequence.get_bwn(name=None) - Get matrix of elements (blocks) with define name.

How get_bwc, but with name.

sequence.to_list() - Converts the sequence to array with order and count.

> seq = dtseqlib.Sequence([["Winter", 1], ["Spring", 2], ["Autumn", 1]])
> print(seq.to_list())

["Winter", "Spring", "Spring", "Autumn"]

len(sequence) - Return count of the elements in sequence.

to_sequence(list) - Return sequence from the list.

> list = [7, 7, 7, 9, 1, 1]
> print(dtseqlib.to_sequence(list))

[[7, 3], [9, 1], [1, 2]]

Downloading

[!WARNING] Library only availble on Python 3.x.

You can install this library by running the following command in your terminal:

pip install dtseqlib

You can use the library after installing.

import dtseqlib

You can use the Sequence() class in your project. Example of project below.

seq = dtseqlib.Sequence([["Spring", 2], ["Winter", 5]])
seq.append("King", 4)
print(seq.get())

Outro

This is my first Python library, and I'm still learning. I will continue updating this project and adding new features.
