Question

Can someone help me make a isogram detector I feel like I'm close but can't figure it out?

word = str(input())
iso = "abcdefghijklmnopqrstuvwxyz"

if sorted(word) >= sorted(iso):
print("false")
else:
print("true")

Marshall Lance Freeman ,

you are not far away from a solution. see your code with some comments and hints:

word = str(input()) # we do not need to convert input to string, input() returns string as default
# iso = "abcdefghijklmnopqrstuvwxyz" # not required

# >>> what is an isogram: a string is called an isogram if it only contains unique characters, no duplicates.

#if sorted(word) >= sorted(iso): this is not applicable to the task description.
# we need to check if there are duplicated characters in the input. this can be done by using a set. set can not hold duplicared characters, so "hello" will be "helo" as a set.
# you can compare the length of the original input string against the input string converted as set.
# if length of both is equal => input is an isogram. if length is different, input is not an isogram

print("false")
else:
print("true")

sorry to say, but your suggested code does fail for all test cases when running it in code coach.
