Mixed function

[Truman]

Thank you for the explanation, I adjusted the code to:

def str_analysis(argstr):
     
    if argstr.isdigit():
        if int(argstr) >= 1000:
            print("We have a big number!")
        else:
            print("we have a small number.")
    
    elif argstr.isalpha():
        print("We have all alphabetic!")
    else:
        print("We have multiple character type")
str_analysis(input("Add string: "))
