Also, a logical error can occur when you pass a string representing a number in a different base toint(), but you fail to specify the appropriate base. In this case,int()will convert the string to decimal without syntax errors, even though you intended a different base. As a result, y...

Question 8 String to Integer (atoi): Implement atoi which converts a string to an integer. The function first discards as many whitespace characters as necessary until the first non-whitespace character is found. Then, starting from this character, takes an optional initial plus or minus sign ...
int()函数可以将字符串转换为整数类型。 如果你想使用lambda函数来实现相同的功能,可以按照以下方式编写代码: 代码语言:txt 复制 string_num = "123" convert_to_int = lambda x: int(x) int_num = convert_to_int(string_num) print(int_num) 输出结果仍然为: 代码语言:txt 复制 123 在上述示例中,我们...
