python的将int强制转化为string python怎么把int转成string 使用struct.pack一定要注意是在64位系统还是32位系统。 如struct.pack('L', 1) 返回长度在64位系统 返回长度是8,32位系统 回返是4 以下自己写个转换算法 DWORD_LEN = 4 #为32位系统 CONST_SQRT = [256 ** i for i in range(DWORD_LEN)]...
将情况都考虑进去 1. 空字符串:返回 2. 从前往后遍历,发现空格,i++ 3. 若有符号,存储sign(flag) 4. 字符串转整数,result = result * 10 + ord(str[i]) - ord('0'),如果溢出直接返回MAX或MIN
