#Python: The given program reads a list of single-word first names and ages (ending with -1), and outputs that list with the age incremented. The program fails and throws an exception if the second input on a line is a string rather than an integer. At FIXME in the code, add try and except blocks to catch the ValueError exception and output 0 for the age.

Ex: If the input is:

Lee 18
Lua 21
Mary Beth 19
Stu 33
-1
then the output is:

Lee 19
Lua 22
Mary 0
Stu 34

"# Split input into 2 parts: name and age
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.
age = int(parts[1]) + 1
print('{} {}'.format(name, age))

# Get next line
parts = input().split()
name = parts[0]"

Respuesta :

The program illustrates the use of catching exceptions.

What are exceptions?

Exceptions are program statements that are used to control program errors, and prevent a program from crashing.

How to fix write the exception

The statements that catch the exception in the program are:

try:

       age = int(parts[1]) + 1

       print('{} {}'.format(name, age))

       # Get next line

       parts = input().split()

       name = parts[0]

   except ValueError:

       print('Invalid value!')

       # Get next line

       parts = input().split()

       name = parts[0]

The complete program

The complete program is as follows:

# Split input into 2 parts: name and age

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))

       # Get next line

       parts = input().split()

       name = parts[0]

   except ValueError:

       print('Invalid value!')

       # Get next line

       parts = input().split()

       name = parts[0]
