【作业】Week 1. Introduction Programming Exercises-Week 1

1、 问题:Please write a program to implement the following function: Enter a string from the keyboard, and print it on the screen.
Tips:
1. Install the Python programming environment on your computer, and then write the program and run it. You should ensure that the outputs of the program on your computer are consistent with the given examples before you submit the program to the OJ (Online Judge) platform.
2. When the OJ platform evaluates the submitted program, it may use other testing cases. So you should write the program according to the requirement of the programming exercise, instead of writing the code that is only aimed at the given input/output examples.
3. Any redundant output will make the program fail to pass the testing of the OJ platform. For example, the correct output is:
Li Xiaoming
the OJ platform will report an error if the output is:
Name: Li Xiaoming
Note that when calling the input function, if we pass the prompt such as "Please input a string:", the OJ platform will also report an error since the output of the submitted program is:
Please input a string:
Li Xiaoming
