Can anybody help me how to write this function.. I tried several methods but unable to write the correct code..

Question

#Imagine you're writing a cash register application. To make
#interaction easier on the user, it doesn't have separate
#areas for passwords, PIN numbers, or cash totals --
#instead, it looks at what the cashier enters and infers
#whether it's their PIN number, their password, or the cash
#total for a transaction.
#
#The register makes this decision with the following rules:
#
# - If the cashier entered only digits, then it's a PIN
# number.
# - If the cashier entered a decimal number, then it's the
# transaction amount.
# - If the cashier entered anything else, then it's their
# password.
#
#Write a function named interpretCashier. interpretCashier
#should take one parameter as input, which will always be
#a string initially.
#
# - If the string entered represents a PIN number, return
# "PIN".
# - If the string entered represents a transaction amount,
# return "Transaction".
# - If the string entered represents a password, return
# "Password".
#
#Hint: There is a very easy way to do this, and a very hard
#way to do this. Remember, this test is on control
#structures, not strings.

#Write your function here!

# if not Transaction and not Password:
# PIN = True
# return "PIN"
# print("Password=", Password)
# print("Trans=", Transaction)
# print("PIN = ", PIN)

#The lines of code below will test your function. It is not
#used for grading, so feel free to change it. As written,
#these lines should print Transaction, PIN, and Password,
#each on a separate line.
print(interpretCashier("2459."))
#print(interpretCashier("123456"))
#print(interpretCashier("my$up3rs3cur3p4$w0rd"))
#print(interpretCashier("25.0"))

Thank you all for your input.
i finally figured it out.
def interpretCashier(my_string):
numlist = ["0","1","2","3","4","5","6","7","8","9"]
allnumber = False
foundchara = False
i = 0
for chara in my_string:
if chara in numlist:
allnumber = True
else :
foundchara = True
nextchara = my_string[i+1]
break
i +=1
if foundchara == True and chara == "." and nextchara != "." :
return "Transaction"
elif foundchara == False and allnumber == True:
return "PIN"
else:
return "Password"

Answer 6

def interpretCashier(a):
try:
bool(int(a)) == True
return "PIN"
except ValueError:
return "Password"

I tried this but I am facing a problem as I am getting Password two times, the decimal part in which I am getting password is wrong and how should I make it right?? Any suggestions??
