The range() Function

If you do need to iterate over a sequence of numbers, the built-in function range() comes in handy. It generates lists containing arithmetic progressions, e.g.:

>>> range(10)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

The given end point is never part of the generated list; range(10) generates a list of 10 values, exactly the legal indices for items of a sequence of length 10. It is possible to let the range start at another number, or to specify a different increment (even negative):

>>> range(5, 10)
[5, 6, 7, 8, 9]
>>> range(0, 10, 3)
[0, 3, 6, 9]
>>> range(-10, -100, -30)
[-10, -40, -70]

To iterate over the indices of a sequence, combine range() and len() as follows:

>>> a = ['Mary', 'had', 'a', 'little', 'lamb']
>>> for i in range(len(a)):
...     print i, a[i]
... 
0 Mary
1 had
2 a
3 little
4 lamb

My example:

x=[‘mastery25′,’tc1014’]

for i in range (len(x)):

     print (“#”,x[i])

>>>#mastery25

>>>#tc1014

#mastery25

#tc1014

Creation and use of arrays in C++ #TC1017 #Mastery24

An array is a data structure, or more technically, a memory that stores a collection of items, all of the same type. Should imagine an array as a contiguous sequence of cells (memory spaces), or squares, each of which can save an item from the collection. Also, it is usual to draw as illustrated by the following figure:

This figure represents an array of seven squares each of which can be used to store a data. The dimension or size of an array is the number of cells that comprise it. It should be clear, then, that the above figure corresponds to an array of dimension 7.

Example of dimension

In 2 dimension be like

At the beginning I was thinking like how to do a sudoku in this way so here is and example

STEPS!!!

1. Type of Variable
2. Write array
3. Name of the array

EXAMPLE:

     float array [A];

In this Code that I did, I wrote some comments explaining what it means each line 

LINKS that I Used to explain and do my WSQ’s and this awesome Mastery 😀
