Checking If Any Character In A String Is Alphanumeric

I want to check if any character in a string is alphanumeric. I wrote the following code for that and it's working fine: s = input() temp = any(i.isalnum() for i in s) print(temp

Solution 1:

In your second function you apply any to a single element and not to the whole list. Thus, you get a single bool element if character i is alphanumeric.

In the second case you cannot really use any as you work with single elements. Instead you could write:

for i in s:
    if i.isalnum():
        print(True)
        break

Which will be more similar to your first case.

Solution 2:

any() expects an iterable. This would be sufficient:

isalnum = Falsefor i in s:
    if i.isalnum():
        isalnum = Truebreakprint(isalnum)
