Answer:
The modified program is as follows:
user_val = int(input())
cond_str = 'non-negative'
if user_val < 0:
cond_str = 'negative'
print(user_val, 'is', cond_str)
Step-by-step explanation:
This gets input for user_val
user_val = int(input())
This initializes cond_str to 'non-negative'
cond_str = 'non-negative'
If user_val is less than 0
if user_val < 0:
cond_str is updated to 'negative'
cond_str = 'negative'
This prints the required output
print(user_val, 'is', cond_str)
