Python List Data Structure

A Python List Data Structure is an Python array that is a Python built-in data structure.

• Context:
  • It can be the input to an Array-input Python Subroutine, such as a Python Join Subroutine.
  • It can be:
    • a Python Tuple for a tuple data structure.
    • a Python Vector for a vector data structure.
    • a Python Array of Arrays, such as a Perl Matrix.
    • a Python Array of Hashes.
• Example(s):
  • a @Tuple = ("One", "2", "11")
• Counter-Example(s):
  • a Numpy Array.
  • a Python Associative Array.
  • a Perl Array.
• See: Python Coding Example, Python Built-In Datatype.

Populate manually

Matrix = [[0 for x in xrange(5)] for y in xrange(6)] 
Matrix[4][3] = 99
Matrix

xx =  numpy.array([2, 4, -11])
yy = zeros(3, Int)        # Create empty array ready to receive result

Populate from a file.

Loops

for i in range(0, 3):
  Matrix[i] = i * 2
print yy
#    [  4   8 -22]

Transforming into a string

Emptying

Random

import random;
#Generate 1000 random integer numbers which are between 1 and 9999(included).
Z=random.sample(range(1,9999),1000);
type(Z)
