Oh yes, Python has an array type, but you must import module array:
# module array has Python's array type
# Python25 use 'c' as the character typecode
# Python30 uses unicode character typecode 'u'
char_array = array.array('c', 'hello world')
print(char_array) # h
print(char_array) # array('c', 'hello world')
# 'i' uses a signed integer of 2 bytes
int_array = array.array('i', [2, 4, -11])
print(int_array) # -11
print(int_array) # array('i', [2, 4, -11])
# 'f' uses 4 bytes and 'd' uses 8 bytes per element
float_array = array.array('d', [1.0, 2.0, 3.14])
print(float_array) # 3.14
for n in float_array:
# get more information on module array
Arrays are sequence types and behave very much like lists, except that the type of objects stored in them is constrained. The type is specified at object creation time. Arrays use up less space in memory, for a limited number of applications this is important.
Need some help with this Array. I am trying to get the sum of the even numbers and the sum of the odd numbers using a for each loop. I know the answers to what I am trying to achive are sum of even = 84 and the sum of ...
I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).
the function that I created to find the ...
