for sum in range(100,1000): if sum == sum(int(x) ** 3 for x in str(sum)): print(sum) 运行出错

您好,这段代码有一些语法错误和逻辑问题。可以尝试以下代码:
```python
for num in range(100, 1000):
if num == sum(int(x) ** 3 for x in str(num)):
print(num)
```
这里将变量名从`sum`改为`num`,避免与Python内置函数`sum()`重名。同时,将`range()`函数的参数分隔开,添加了缩进,调整了代码格式。您可以尝试运行一下看看是否能够得到正确的结果。

def is_palindrome(n): return str(n) == str(n)[::-1]n = int(input())if n < 1 or n > 54: print("输入错误,请重新输入!")else: found = False for i in range(10000, 100000): if is_palindrome(i) and is_palindrome(i*11): digits_sum = sum([int(d) for d in str(i)]) if digits_sum == n: print(i) found = True for i in range(100000, 1000000): if is_palindrome(i) and is_palindrome(i//10): digits_sum = sum([int(d) for d in str(i)]) if digits_sum == n: print(i) found = True if not found: print("无满足条件的数")
这是一个判断各位数字之和等于n的5位和6位十进制回文数的Python程序,如果输入的数不在指定的范围内,则输出"输入错误,请重新输入!",如果没有符合条件的数,则输出"无满足条件的数"。
具体来说,这个程序先定义了一个函数is_palindrome(n),用来判断一个数n是否为回文数,然后读入一个正整数n,如果n不在1到54之间,则输出"输入错误,请重新输入!";否则,程序从10000到99999和100000到999999之间遍历所有的5位和6位回文数,判断它们的各位数字之和是否等于n,如果是,则输出这个回文数,并将found设置为True。最后,如果没有找到符合条件的数,则输出"无满足条件的数"。
需要注意的是,这个程序的实现有一个小问题,即没有考虑到输入的数为0的情况,因为0不在1到54之间,但它的各位数字之和等于0,因此应该输出一个0。可以将第3行的判断条件修改为n <= 0 or n > 54,然后在第7行添加一个特判即可。
for num in range(100,1000): r=map(lambda x:int(x)**3,str(num)) if sum(r)==num: print(num)
As an AI language model, I cannot execute code, but I can explain what this code does.
This code is checking for all three-digit numbers that are equal to the sum of the cubes of their digits.
The code first iterates through all numbers from 100 to 999 using the `range()` function.
For each number, it converts it to a string and then maps the `int()` function to each digit in the string to convert it to an integer. It then cubes each integer using the `**` operator and returns the list of cubes.
The `sum()` function is then used to add up all the cubes, and if the sum equals the original number, it is printed to the console.
This code is an example of a brute-force approach to solving a problem, as it simply checks every possible three-digit number until it finds the ones that meet the criteria.
