[Tutor] Python strings example

[Manprit Singh]

Dear sir,

consider a problem where I have to write a function that can return True if
the string passed to the function contains at least one digit character and
one alphabet character, else the function must return False. The way i am
solving it is given below :
def str_chk(word_tochk):
    dig = False
    alpha = False
    for ele in word_tochk:
        dig = dig or ele.isdigit()
        alpha = alpha or ele.isalpha()
    return dig and alpha


st = "Abhay2"
ans = str_chk(st)
print(ans) returns True, which is correct as the string contains an
alphabet as well as a digit character.

st = "Abhay"
ans = str_chk(st)
print(ans) returns False . which is also correct as there is no digit
character in the string now

Any suggestions, if the solution can be improved .
