Perl中如何实现与Python的array.array(typecode, ...)等价的功能? Python的array.array在Perl中有没有直接的对应物? 在Perl中,如何创建一个指定类型的数组,类似于Python的array.array? 在Python中,array.array()是一个用于创建固定类型数组的内置类。它可以存储相同类型的数据,并且比

原因:input()函数输入的是字符串格式,所以自己在键盘输入的整数其实并不是正整数,而是字符串形式。所以在执行语句num3=num*num会报错。因为num1和num2都是字符串形式,不可以相乘。 解决思路:把num1和num2强制转换成整数 具体解决方法 1.代码第三行改为: num3=int(num1)*int(num2) ...
