Final answer:
The student's nested if statements can be converted to an if-elif-else block to streamline the code, checking each condition sequentially and printing 'One', 'Two', 'Three', or 'Unknown' accordingly.
Step-by-step explanation:
The student's question involves converting a series of nested if statements into a single if-elif-else statement in programming. This would make the code cleaner and more efficient to read. Here is how you can convert the given nested if statements into an if-elif-else block:
if number == 1:
print('One')
elif number == 2:
print('Two')
elif number == 3:
print('Three')
else:
print('Unknown')
This structure is more straightforward than nested if statements as it allows the program to check each condition one by one and execute the corresponding print statement. If none of the conditions match, the else block will execute, printing 'Unknown'.
