如何修改Python代码以仅调用一次print函数？

Hey there! Your existing code works exactly as intended, but since the requirement is to use only one print() call, we can simplify things with Python's ternary conditional expression. Here's how to adjust it:

Modified Code #

number = input('Please enter a number: ')
number = int(number)
print(number if number > 1 else -number)

How It Works #

The ternary expression number if number > 1 else -number acts like a compact inline if-else statement. It checks the condition number > 1:

• If the condition is true, it returns the original number
• If the condition is false, it returns -number

This computed value is passed directly to print() in a single call, so we meet the requirement without changing the original logic at all.

If you prefer a more explicit, readable approach, you can also store the result in a variable first before printing:

number = input('Please enter a number: ')
number = int(number)
output_value = number if number > 1 else -number
print(output_value)

Either version will produce the exact same output as your original code, but with only one print() invocation.
