[Python] Python detect string and int using exception handling

I am trying to work on detecting strings and int using exception handling and cannot figure it out. Please help!

Using the inputs

• Lee 18
• Lua 21
• Mary Beth 19
• Stu 33
• -1

parts = input().split()
name = parts[0]

while name != '-1':

# FIXME: The following line will throw ValueError exception.
# Insert try/except blocks to catch the exception.
try:
age = int(parts[1]) + 1
print('{} {}'.format(name, age))
parts = input().split()
name = parts[0]
if age != 0:
raise ValueError(0)
except ValueError as excpt:
name = parts[0]
age = excpt
