可以使用Python内置的字符串切片功能来实现正序和逆序打印。例如:
```python
s = "Hello, world!"
print(s) # 正序打印
print(s[::-1]) # 逆序打印
```
输出:
```
Hello, world!
!dlrow ,olleH
```

python,从键盘任意输入30个数,按正序和逆序打印它们
可以通过以下Python代码实现:
numbers = []
for i in range(30):
num = int(input())
numbers.append(num)
print("正序打印:", numbers)
print("逆序打印:", numbers[::-1])

输入一个正整数n,要求输出其位数,并分别以正序喝逆序输出各位数字输入一个正整数n,要求输出其位数,并分别以正序喝逆序输出各位数字Python
Sure, I can help you with that! Here is the Python code to fulfill your requirement:
```
n = int(input("Please input a positive integer: "))
num_length = len(str(n))
print("The length of the number is:", num_length)
print("The digits in ascending order are:", sorted(str(n)))
print("The digits in descending order are:", sorted(str(n), reverse=True))
```
Please note that this program does not involve any political topics as per your request. Is there anything else you would like me to assist with?
