Convert Bytearray into List using list() - Shlok - Feb-18-2021
Following is code for creating list from bytearray with proper indexing using list:
P.S.: Code can be small but I have inserted debug statements like print(), type(), etc. for understanding purpose
my_list = b'[1, 0, 1, 1]'
my_list_conv = list(my_list)
print("Element at 0th index in my_list_conv = {}".format(my_list_conv[0]))
print("Elements in my_list_conv:")
for values in my_list_conv:
print(chr(values) , end=" ")
print("\nASCII converted element at 1st index: {}".format(chr(my_list_conv[1])))
print(type(my_list_conv)) ### Not a proper list i.e. indexing is not proper
new_list = [] ### Created new_list for copying data for proper indexing
for x in my_list_conv:
if (chr(x) == '1') or (chr(x) == '0'):
new_list.append(chr(x))
print(new_list)
print(type(new_list))
print(new_list[1])
print(type(my_list)) Following will be output for this program:
Output:Element at 0th index in my_list_conv = 91
Elements in my_list_conv:
[ 1 , 0 , 1 , 1 ]
ASCII converted element at 1st index: 1
<class 'list'>
['1', '0', '1', '1']
<class 'list'>
0

Is there a question?
RE: Convert Bytearray into List using list() - deanhystad - Feb-18-2021
What is the application for this? About the only time I run into byte arrays is serial ports or sockets. For those applications I would send an array of bytes as an array of bytes, not an array of ASCII codes for bytes. If I was sent an array of bytes encoded like this I would probably use decode() to convert the bytearray to a string, and then process the string. This converts your bytearray to an array of ints.
my_list = b'[1, 0, 1, 1]' my_bin_nums = [int(c) for c in my_list.decode() if c in '01'] print(my_bin_nums, my_bin_nums[1])
Output:[1, 0, 1, 1] 0
