Python binary converter problem

[Ethan_Wright]

im having trouble with this code
con_input = input("1.binary-decimal 2.binary-ASCII 3.binary-hexadecimal\n-\n4.decimal-binary 5.ASCII-binary 6.hexadecimal-binary\n> ")




if con_input != "1" and con_input != "2" and con_input != "3" and con_input != "4" and con_input != "5" and con_input != "6":
print("enter one of the numerical options")


def code_conversion():
if con_input == "1":
print("separate bytes by a space")
binary_input = input("enter binary:\n> ")
int(binary_input)
while len(binary_input) < 8:
print("please enter a 8bits or higher")
binary_input = input("enter binary:\n> ")
while "1" not in binary_input and "0" not in binary_input:
error = ("Please enter binary")
print("\nseparate bytes by a space")
binary_input = input("enter binary:\n> ")
binary_input = list(binary_input)
if [0] in binary_input == '1':
binary_input[0] = '128'
print(binary_input)

code_conversion()




im trying to turn items in the list into their binary coversion depending if they are a 0 or a 1 however when I try it it does not seem to change to the 128 it just stays as the 1.

any help with this would be greatly appreciated :D
