print(type(testlist[0])) print(type(testlist[1])) 1. 2. 3. 4. 5. 运行结果如下: 1 测试 <class 'int'> <class 'str'> 1. 2. 3. 4. 通过结果可见,列表里的数据跟从键盘输出的原数据类型一致,并未发生改变。好了,知道这些后我们进行今天的内容讲解:python里列表的“增删改查” 一、增: ...

Write a program using Python that accepts a character as an input. The program should check using the nested decision statements and check the following: If the character is an alphabet, then it should check if it is a vowel or conso...
The write() function takes string as the argument. So, we’ll be using the for loop again to iterate on each element in the list and write it to the file. Here’s a sample Python program: MyList = ["New York", "London", "Paris", "New Delhi"] ...
