Question

Write a function “ssnChecker” that takes a string “s” and validates if the string is in a valid social security number format (999-99-9999). The function must return a Boolean value (True or False).

Answer 1

def ssnChecker(s):
    if len(s)==13:
        for i in range(len(s)):
            if i==0:
                if s[i]!="(":
                    return False
            elif (i>=1 and i<=3) or (i>=5 and i<=6) or (i>=8 and i<=11):
                if not (s[i]>='0' and s[i]<='9'):
                    return False
            elif i==12:
                if s[i]!=")":
                    return False
            else:
                if s[i]!="-":
                    return False
        return True
    else:
        return False

# Testing
print(ssnChecker("(999-99-9999)"))
print(ssnChecker("(999-99-999"))
