我们定义了两个函数:input_students()和output_students(),用于输入和输出学生的数据记录。 在input_students()函数中,我们使用循环来输入每个学生的姓名、年龄和成绩,并将其存储在一个字典中,然后将字典添加到一个列表中。 在output_students()函数中,我们使用循环和字符串格式化来逐个输出学生的数据记录。 在主程序...
Input and Output Input Python’s input function takes a single parameter that is a string. This string is often called thepromptbecause it contains some helpful text prompting the user to enter something. For example, you might call input as follows: aName=input('Please enter your name: ')...
Python allows you to use the popular data interchange format calledJSON (JavaScript Object Notation).
