Unable to execute the same script in Leetcode but works fine with VSCode TypeError: 'int'-CodePudding

Below code works fine with VScode but running the same on Leetcode compiler got this error

int object is not iterable for the loop for i in s:

def isPalindrome(s):
    rev = ""
    #print(s)
    for i in s:
        rev = i  rev
    #print(rev)
    if (rev == s):
        return True
    else:
        return False
print(isPalindrome("-121"))```



    TypeError: 'int' object is not iterable
        for i in s:
    Line 4 in isPalindrome (Solution.py)
        ret = Solution().isPalindrome(param_1)
    Line 32 in _driver (Solution.py)
        _driver()
    Line 42 in <module> (Solution.py)



Can anyone point out what am i missing here? I dont thing the code is incorrect here.

CodePudding user response：

Maybe you should try to use a list explicitly instead of the string. Here is an example:

def isPalindrome(s):
    return s == s[::-1]

print(isPalindrome(list("-121")))

CodePudding user response：

Apparently, Leetcode gives you real number type. You needs to add s = str(s) to ensure the input is a string.
