一般使用的时候直接 list.reverse()print(list)就行
>>> reversed(li) <list_reverseiterator object at 0x000002CF0EF6A940> >>> for n in reversed(li): ... print(n) ... 4 3 2 1 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. round(number[, ndigits]) 四舍五入 >>> round(3.3) 3 >>> round(3.7) 4 1. 2. 3. 4. set([iterable...
除了使用切片运算符[::-1],你还可以使用reverse()函数来反转字符串。
```pythonstring = input("请输入一个字符串:")reverse_string = string[::-1]print("逆序输出的结果为:", reverse_string)``` 答案 解析 null 本题来源 题目:四、编程题编写一个Python程序,实现将输入的字符串逆序输出的功能。```pythonstring = input("请输入一个字符串:")reverse_string = string[:...
内置函数就是Python给你提供的, 拿来直接用的函数,比如print,input等。 截止到python版本3.6.2 ,一共提供了68个内置函数,具体如下 abs() dict() help() min() setattr() all() dir() hex() next() slice() any() divmod() id() object() sorted() ...
更进一步,我们也可以通过传递reverse=True对其进行降序排序: sorted_d= dict(sorted(d.items, key=itemgetter(1), reverse=True)) Pretty print 在Python中使用Print函数,有时候的输出贼拉拉丑陋,此时我们使用pprint可以使输出更加美观,样例如下: frompprintimportpprintdata = {"name":"john deo","age":"22","...

To iterate range in reverse order, we use 3 parameters Start – start value Stop – end value Step – Increment/Decrement to the value Examples 1) To print numbers from B to A for i in range(B, A-1, -1) print i 2) To print numbers from B to A by escaping one number between ...
Run a for loop to iterate the list elements. Convert each element to a string using str() method. Check the number (converted to string) is equal to its reverse. If the number is equal to its reverse, print it.Python program to print Palindrome numbers from the given list#...
