How do I write an if statement to check if each number in a 9 digit number is unique? Clearly the if statement I wrote (see the bold line) isn't working. Would appreciate any help!!
x_raw = int(input("Please input a 9 digit number where no digit appears twice"))
x_nexthighestnumber = x_raw + 1
x = str(x_nexthighestnumber)
number = "incorrect"
while (x_nexthighestnumber < 999999999 and number == "incorrect"):
**if (x[0] != x[1] != x[2] != x[3] != x[4] != x[5]!= x[6] != x[7] != x[8]):**
number = "correct"
print (x)
else:
number = "incorrect"
x_nexthighestnumber += 1
