how to convert integer to hex signed 2's complement in python
<![CDATA[def hex2complement(number):
hexadecimal_result = format(number, "03X")
return hexadecimal_result.zfill(4) # .zfill(n) adds leading 0's if the integer has less digits than n
# Examples:
# print(hex2complement(10)) outputs "000A"
# print(hex2complement(100)) outputs "0064"
# print(hex2complement(1000)) outputs "03E8"
# print(hex2complement(10000)) outputs "2710"
# print(hex2complement(100000)) outputs "186A0"]]>
