Method Name:
extend()
Signature:
extend(iterable)
Return Value:
None
Exceptions:
Type Error – when the Python iterable or the array object passed in is not same as the base type of the array.
Overview:
- An array object can be added with more members from a Python iterable or from another array by calling the extend() method and passing in an array or iterable.
Example:
|
# An example Python program that extends a Python array # with elements from a Python iterable import array
# Create an array chars = array.array('B');
# Array with ASCII code for small letters for val in range(97, 123): chars.append(val);
print("ASCII code for small letters:"); print(chars);
# Create a Python list caps = []; for val in range (65, 91): caps.append(val);
# Extend the array to include ASCII code for small letters chars.extend(caps); print("ASCII code for small and capital letters:"); print(chars); |
Output:
|
ASCII code for small letters: array('B', [97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122]) ASCII code for small and capital letters: array('B', [97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90]) |
