如何在不对每个字符串应用center方法的情况下将程序中的所有put语句居中？

def center_align(string):
    total_width = 80  # 总宽度，可以根据实际情况调整
    string_width = len(string)
    if string_width >= total_width:
        return string  # 字符串长度超过总宽度，不进行居中对齐
    left_spaces = (total_width - string_width) // 2
    right_spaces = total_width - string_width - left_spaces
    centered_string = ' ' * left_spaces + string + ' ' * right_spaces
    return centered_string

# 示例使用
put_statement = "Hello, world!"
centered_statement = center_align(put_statement)
print(centered_statement)
