We can use the insert() method to insert a value at any index of the array. Here is an example : my_array = array('i', [1,2,3,4,5]) my_array.insert(0,0) #array('i', [0, 1, 2, 3, 4, 5]) In the above example, the value 0 was inserted at index 0. Note that the first argument is the index while se...

A python array can be extended with more than one value using extend() method. Here is an example : my_array = array('i', [1,2,3,4,5]) my_extnd_array = array('i', [7,8,9,10]) my_array.extend(my_extnd_array) # array('i', [1, 2, 3, 4, 5, 7, 8, 9, 10]) We see that the array my_array was extended...

Here is an example: my_array = array('i', [1,2,3,4,5]) c=[11,12,13] my_array.fromlist(c) # array('i', [1, 2, 3, 4, 5, 11, 12, 13]) So we see that the values 11,12 and 13 were added from list c to my_array.

Here is an example : my_array = array('i', [1,2,3,4,5]) my_array.remove(4) # array('i', [1, 2, 3, 5]) We see that the element 4 was removed from the array.

pop removes the last element from the array. Here is an example : my_array = array('i', [1,2,3,4,5]) my_array.pop() # array('i', [1, 2, 3, 4]) So we see that the last element (5) was popped out of array.

index() returns first index of the matching value. Remember that arrays are zero-indexed. my_array = array('i', [1,2,3,4,5]) print(my_array.index(5)) # 5 my_array = array('i', [1,2,3,3,5]) print(my_array.index(3)) # 3 Note in that second example that only one index was returned, even though...

The reverse() method does what the name says it will do - reverses the array. Here is an example : my_array = array('i', [1,2,3,4,5]) my_array.reverse() # array('i', [5, 4, 3, 2, 1])

This method provides you the array buffer start address in memory and number of elements in array. Here is an example: my_array = array('i', [1,2,3,4,5]) my_array.buffer_info() (33881712, 5)

count() will return the number of times and element appears in an array. In the following example we see that the value 3 occurs twice. my_array = array('i', [1,2,3,3,5]) my_array.count(3) # 2

tostring() converts the array to a string. my_char_array = array('c', ['g','e','e','k']) # array('c', 'geek') print(my_char_array.tostring()) # geek

When you need a Python list object, you can utilize the tolist() method to convert your array to a list. my_array = array('i', [1,2,3,4,5]) c = my_array.tolist() # [1, 2, 3, 4, 5]

You are able to append a string to a character array using fromstring() my_char_array = array('c', ['g','e','e','k']) my_char_array.fromstring("stuff") print(my_char_array) #array('c', 'geekstuff')

Sometimes, if an action should be bind to a collection view's cell selection, you have to implement the UICollectionViewDelegate protocol.

Provided that barButtonItem has a non-null image property (e.g. set in the Interface Builder). Objective-C barButtonItem.image = [barButtonItem.image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
