    this question taught me a lot.i didnt even know that python has a concept of for-else,i thought that we can use else with a preceding if but there's more to it. basically in a for-else,the else bloock is exceuted if the loop ran completely and was not interupted by a break statement.

        s = input()
    for i in s:
        if i.isalnum():
            print("True")
            break
    else:        #for else,else executes only when loop isnt broken
        print("False")
    for i in s:
        if i.isalpha():
            print("True")
            break
    else:
        print("False")
    for i in s:
        if i.isdigit():
            print("True")
            break
    else:
        print("False")
    for i in s:
        if i.islower():
            print("True")
            break
    else:
        print("False")
    for i in s:
        if i.isupper():
            print("True")
            break
    else:
        print("False")
